# Wiki.js Change Detection - Complete Setup Guide
|
||||
|
||||
Complete setup instructions for real-time Wiki.js page change detection with loop prevention.
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
This system automatically processes user-edited Wiki.js pages using PostgreSQL database triggers and NOTIFY/LISTEN.
|
||||
|
||||
**Features:**
|
||||
- ✅ Real-time change detection via database triggers
|
||||
- ✅ Read-only database user (security best practice)
|
||||
- ✅ Loop prevention (automated edits don't trigger re-processing)
|
||||
- ✅ Debouncing (prevents duplicate processing)
|
||||
- ✅ Graceful error handling
|
||||
|
||||

|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ User edits page in Wiki.js │
|
||||
└──────────────────┬─────────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ PostgreSQL Trigger fires │
|
||||
│ pg_notify('wiki_page_changes', 'UPDATE:123:...')│
|
||||
└──────────────────┬─────────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ WikiChangeListener (library-desk) │
|
||||
│ ├─ LOOP CHECK #1: Is author automated user? │ ← Prevents loops
|
||||
│ ├─ LOOP CHECK #2: Recently processed? │ ← Debouncing
|
||||
│ └─ Process page (ingest + entity linking) │
|
||||
└──────────────────┬─────────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ Entity linking writes back to Wiki.js │
|
||||
│ (via API as wikijs_username) │
|
||||
└──────────────────┬─────────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌────────────────────────────────────────────────┐
|
||||
│ Trigger fires again BUT... │
|
||||
│ LOOP CHECK #1 catches it: author is │
|
||||
│ automated user → SKIP processing │ ← Loop prevented!
|
||||
└────────────────────────────────────────────────┘
|
||||
```
|
||||

|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Wiki.js running with PostgreSQL database
|
||||
- Library-desk has network access to PostgreSQL
|
||||
- PostgreSQL admin access (for initial setup)
|
||||
|
||||
---
|
||||
|
||||
## Step 1: Create Read-Only Database User
|
||||
|
||||
**Why:** Library-desk only needs to LISTEN for notifications, not modify data. Using a read-only user is a security best practice.
|
||||
|
||||
### Run SQL as PostgreSQL admin:
|
||||
|
||||
```bash
|
||||
docker exec -it postgres psql -U postgres -d wiki
|
||||
```
|
||||
|
||||
Then execute:
|
||||
|
||||
```sql
|
||||
-- Create read-only user for change listener
|
||||
CREATE USER library_desk_listener WITH PASSWORD 'secure_password_here';
|
||||
|
||||
-- Grant minimal permissions
|
||||
GRANT CONNECT ON DATABASE wiki TO library_desk_listener;
|
||||
GRANT USAGE ON SCHEMA public TO library_desk_listener;
|
||||
GRANT SELECT ON TABLE pages TO library_desk_listener;
|
||||
|
||||
-- Verify permissions
|
||||
\du library_desk_listener
|
||||
-- Should show: No roles, just basic login
|
||||
|
||||
-- Test LISTEN capability (important!)
|
||||
\c wiki library_desk_listener
|
||||
LISTEN wiki_page_changes;
|
||||
-- Should succeed even with read-only permissions
|
||||
\q
|
||||
```
|
||||
|
||||
**Save the password** - you'll need it for `.env` configuration.
|
||||
|
||||
---
|
||||
|
||||
## Step 2: Install Database Triggers
|
||||
|
||||
Triggers emit NOTIFY events when pages are created/updated/deleted.
|
||||
|
||||
### Run the setup script:
|
||||
|
||||
```bash
|
||||
docker exec -it library-desk bash
|
||||
cd /app
|
||||
python3 setup_wiki_triggers.py
|
||||
```
|
||||
|
||||
**Expected output:**
|
||||
```
|
||||
======================================================================
|
||||
Wiki.js Database Trigger Setup
|
||||
======================================================================
|
||||
|
||||
Connecting to Wiki.js database at postgres:5432
|
||||
Database: wiki
|
||||
User: wikijs
|
||||
|
||||
✓ Connected to Wiki.js database
|
||||
|
||||
Installing triggers...
|
||||
|
||||
✓ Triggers installed successfully:
|
||||
|
||||
- wiki_page_delete_trigger (DELETE)
|
||||
- wiki_page_insert_trigger (INSERT)
|
||||
- wiki_page_update_trigger (UPDATE)
|
||||
|
||||
======================================================================
|
||||
Setup complete!
|
||||
======================================================================
|
||||
```
|
||||
|
||||
### Manual verification:
|
||||
|
||||
```sql
|
||||
SELECT trigger_name, event_manipulation
|
||||
FROM information_schema.triggers
|
||||
WHERE event_object_table = 'pages'
|
||||
ORDER BY trigger_name;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Configure Environment Variables
|
||||
|
||||
Add to your `services/library-desk/.env`:
|
||||
|
||||
```bash
|
||||
# Wiki.js API User (used for entity linking)
|
||||
# IMPORTANT: This username will be filtered out to prevent loops
|
||||
WIKIJS_USERNAME=your_wikijs_api_username
|
||||
|
||||
# Wiki.js Database Configuration (for change listener)
|
||||
WIKIJS_DB_HOST=postgres
|
||||
WIKIJS_DB_PORT=5432
|
||||
WIKIJS_DB_NAME=wiki
|
||||
WIKIJS_DB_USER=library_desk_listener # Read-only user created in Step 1
|
||||
WIKIJS_DB_PASSWORD=secure_password_here # From Step 1
|
||||
|
||||
# Loop Prevention: Debounce duration (optional, default: 5 seconds)
|
||||
# Prevents processing duplicate notifications for the same page
|
||||
WIKIJS_CHANGE_LISTENER_DEBOUNCE_SECONDS=5
|
||||
```
|
||||
|
||||
**Critical:** The `WIKIJS_USERNAME` must match the Wiki.js user that library-desk uses for API calls. This prevents infinite loops when entity linking updates pages.
|
||||
|
||||
---
|
||||
|
||||
## Step 4: Restart Library-Desk
|
||||
|
||||
```bash
|
||||
docker restart library-desk
|
||||
```
|
||||
|
||||
### Check logs for successful startup:
|
||||
|
||||
```bash
|
||||
docker logs library-desk --tail 50 | grep -E "(Wiki.js change listener|wiki_page_changes)"
|
||||
```
|
||||
|
||||
**Expected log output:**
|
||||
```
|
||||
INFO - Starting Wiki.js database change listener
|
||||
INFO - Listening for Wiki.js page changes via PostgreSQL NOTIFY
|
||||
INFO - Wiki.js change listener started successfully
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Test the System
|
||||
|
||||
### Test 1: Manual Page Edit
|
||||
|
||||
1. **Edit a page in Wiki.js** (add some text)
|
||||
2. **Save the page**
|
||||
3. **Watch library-desk logs:**
|
||||
|
||||
```bash
|
||||
docker logs library-desk --follow | grep -E "(Received|notification|Processing page|Entity linking)"
|
||||
```
|
||||
|
||||
**Expected log output:**
|
||||
```
|
||||
INFO - Received UPDATE notification for page 123 by user@example.com
|
||||
INFO - Processing page.update for page 123 ('Test Page')
|
||||
INFO - Ingesting page 123 into knowledge base
|
||||
INFO - Ingestion complete for page 123
|
||||
INFO - Applying bidirectional entity linking for page 123
|
||||
INFO - Entity linking complete for page 123: 5 forward links, 3 backward links
|
||||
INFO - Successfully processed page.update for page 123
|
||||
```
|
||||
|
||||
### Test 2: Loop Prevention
|
||||
|
||||
After the entity linking completes (which updates the Wiki.js page), you should see:
|
||||
|
||||
```
|
||||
DEBUG - Skipping notification for page 123 - automated edit by wikijs_username (likely entity linking)
|
||||
```
|
||||
|
||||
**This means loop prevention is working!** The automated edit triggered a notification, but the listener correctly filtered it out.
|
||||
|
||||
### Test 3: Debouncing
|
||||
|
||||
If you rapidly save the same page multiple times (within 5 seconds), you should see:
|
||||
|
||||
```
|
||||
INFO - Received UPDATE notification for page 123 by user@example.com
|
||||
INFO - Processing page.update for page 123...
|
||||
DEBUG - Skipping notification for page 123 - processed within last 5s (debouncing)
|
||||
DEBUG - Skipping notification for page 123 - processed within last 5s (debouncing)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Loop Prevention Details
|
||||
|
||||
The system has **two layers of loop prevention**:
|
||||
|
||||
### Layer 1: Automated User Filtering
|
||||
|
||||
**Problem:** Entity linking updates Wiki.js pages via API, which triggers database changes, which triggers notifications again.
|
||||
|
||||
**Solution:** Filter out notifications where the author matches `WIKIJS_USERNAME`:
|
||||
|
||||
```python
|
||||
# In wiki_change_listener.py:125-141
|
||||
def _is_automated_user(self, email: str) -> bool:
|
||||
automated_users = [
|
||||
self.settings.wikijs_username, # Your Wiki.js API user
|
||||
"library-desk@system",
|
||||
"automation@system"
|
||||
]
|
||||
return email.lower() in [u.lower() for u in automated_users]
|
||||
```
|
||||
|
||||
**Customize:** If you use different automation users, add them to the list.
|
||||
|
||||
### Layer 2: Debouncing
|
||||
|
||||
**Problem:** Multiple rapid notifications for the same page (network hiccups, Wiki.js behavior).
|
||||
|
||||
**Solution:** Track recently processed pages and ignore duplicates within N seconds:
|
||||
|
||||
```python
|
||||
# In wiki_change_listener.py:143-164
|
||||
def _is_recently_processed(self, page_id: int) -> bool:
|
||||
if page_id not in self._recent_notifications:
|
||||
return False
|
||||
|
||||
last_processed = self._recent_notifications[page_id]
|
||||
elapsed = (datetime.now() - last_processed).total_seconds()
|
||||
|
||||
return elapsed < self._debounce_seconds # Default: 5 seconds
|
||||
```
|
||||
|
||||
**Configure:** Set `WIKIJS_CHANGE_LISTENER_DEBOUNCE_SECONDS` in `.env` (1-60 seconds).
|
||||
|
||||
---
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Check Listener Status
|
||||
|
||||
```bash
|
||||
# Is listener running?
|
||||
docker logs library-desk --tail 50 | grep "Wiki.js change listener"
|
||||
|
||||
# Expected: "Wiki.js change listener started successfully"
|
||||
```
|
||||
|
||||
### Monitor Real-Time Changes
|
||||
|
||||
```bash
|
||||
# Watch for page change notifications
|
||||
docker logs library-desk --follow | grep -E "(Received|Processing page|Entity linking|Skipping)"
|
||||
```
|
||||
|
||||
### Check Loop Prevention Stats
|
||||
|
||||
```bash
|
||||
# Count automated user filters (should be non-zero after entity linking runs)
|
||||
docker logs library-desk | grep "automated edit" | wc -l
|
||||
|
||||
# Count debouncing skips
|
||||
docker logs library-desk | grep "debouncing" | wc -l
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Listener Not Starting
|
||||
|
||||
**Error:** `Failed to start Wiki.js change listener`
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Check database connection:**
|
||||
```bash
|
||||
docker exec library-desk ping postgres
|
||||
```
|
||||
|
||||
2. **Test database credentials:**
|
||||
```bash
|
||||
docker exec library-desk psql -h postgres -U library_desk_listener -d wiki -c "\dt"
|
||||
```
|
||||
|
||||
3. **Verify user exists:**
|
||||
```bash
|
||||
docker exec postgres psql -U postgres -d wiki -c "\du library_desk_listener"
|
||||
```
|
||||
|
||||
### Changes Not Being Processed
|
||||
|
||||
**Problem:** Page edits but no logs appear
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Verify triggers installed:**
|
||||
```bash
|
||||
docker exec postgres psql -U postgres -d wiki -c "
|
||||
SELECT trigger_name FROM information_schema.triggers
|
||||
WHERE event_object_table = 'pages';
|
||||
"
|
||||
```
|
||||
Should list 3 triggers (INSERT, UPDATE, DELETE).
|
||||
|
||||
2. **Test notification manually:**
|
||||
```bash
|
||||
docker exec postgres psql -U postgres -d wiki -c "
|
||||
NOTIFY wiki_page_changes, 'TEST:999:test@example.com';
|
||||
"
|
||||
```
|
||||
Check library-desk logs for "Received TEST notification".
|
||||
|
||||
3. **Check authorEmail field exists:**
|
||||
```bash
|
||||
docker exec postgres psql -U postgres -d wiki -c "
|
||||
SELECT column_name FROM information_schema.columns
|
||||
WHERE table_name = 'pages' AND column_name = 'authorEmail';
|
||||
"
|
||||
```
|
||||
|
||||
### Infinite Loop Detected
|
||||
|
||||
**Symptoms:** Continuous processing logs for the same page
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Verify WIKIJS_USERNAME is correct:**
|
||||
```bash
|
||||
docker exec library-desk env | grep WIKIJS_USERNAME
|
||||
```
|
||||
Must match the Wiki.js username library-desk uses for API calls.
|
||||
|
||||
2. **Check automated user filtering:**
|
||||
```bash
|
||||
docker logs library-desk | grep "automated edit"
|
||||
```
|
||||
If you see no "Skipping" logs, the filter isn't working.
|
||||
|
||||
3. **Manually stop processing:**
|
||||
```bash
|
||||
docker restart library-desk
|
||||
```
|
||||
Then fix the `WIKIJS_USERNAME` configuration.
|
||||
|
||||
### Permission Denied
|
||||
|
||||
**Error:** `permission denied to create trigger`
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Run trigger setup as postgres admin:**
|
||||
```bash
|
||||
docker exec -it postgres psql -U postgres -d wiki
|
||||
# Then run setup_wiki_triggers.py with admin user
|
||||
```
|
||||
|
||||
2. **Grant trigger creation permission:**
|
||||
```sql
|
||||
GRANT CREATE ON DATABASE wiki TO wikijs;
|
||||
ALTER TABLE pages OWNER TO wikijs;
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Configuration Reference
|
||||
|
||||
### Environment Variables
|
||||
|
||||
| Variable | Default | Description |
|
||||
|----------|---------|-------------|
|
||||
| `WIKIJS_USERNAME` | *required* | Wiki.js API user (for loop prevention) |
|
||||
| `WIKIJS_DB_HOST` | `postgres` | PostgreSQL host |
|
||||
| `WIKIJS_DB_PORT` | `5432` | PostgreSQL port |
|
||||
| `WIKIJS_DB_NAME` | `wiki` | Wiki.js database name |
|
||||
| `WIKIJS_DB_USER` | `library_desk_listener` | Read-only database user |
|
||||
| `WIKIJS_DB_PASSWORD` | *required* | Database password |
|
||||
| `WIKIJS_CHANGE_LISTENER_DEBOUNCE_SECONDS` | `5` | Debounce duration (1-60s) |
|
||||
|
||||
### Automated Users List
|
||||
|
||||
Edits by these users are filtered out to prevent loops:
|
||||
|
||||
```python
|
||||
automated_users = [
|
||||
self.settings.wikijs_username, # From WIKIJS_USERNAME
|
||||
"library-desk@system",
|
||||
"automation@system",
|
||||
"bot@system"
|
||||
]
|
||||
```
|
||||
|
||||
**Customize:** Edit `wiki_change_listener.py:134-139` to add your automation users.
|
||||
|
||||
---
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
✅ **Read-only database user** - `library_desk_listener` cannot modify data
|
||||
✅ **No direct database writes** - All Wiki.js updates go through API
|
||||
✅ **Loop prevention** - Automated edits don't trigger re-processing
|
||||
✅ **Error isolation** - Listener failures don't affect Wiki.js
|
||||
✅ **Connection resilience** - asyncpg handles reconnection automatically
|
||||
|
||||
---
|
||||
|
||||
## Uninstalling
|
||||
|
||||
To remove the change detection system:
|
||||
|
||||
### 1. Stop the listener:
|
||||
|
||||
Edit `src/main.py` and comment out lines 354-364 (listener startup).
|
||||
|
||||
### 2. Remove database triggers:
|
||||
|
||||
```bash
|
||||
docker exec -it postgres psql -U postgres -d wiki -c "
|
||||
DROP TRIGGER IF EXISTS wiki_page_insert_trigger ON pages;
|
||||
DROP TRIGGER IF EXISTS wiki_page_update_trigger ON pages;
|
||||
DROP TRIGGER IF EXISTS wiki_page_delete_trigger ON pages;
|
||||
DROP FUNCTION IF EXISTS notify_page_change();
|
||||
"
|
||||
```
|
||||
|
||||
### 3. Remove read-only user:
|
||||
|
||||
```bash
|
||||
docker exec -it postgres psql -U postgres -d wiki -c "
|
||||
DROP USER IF EXISTS library_desk_listener;
|
||||
"
|
||||
```

## Features Implemented
|
||||
|
||||
### ✅ 1. **Page Creation** (`page.create`)
|
||||
- Triggers full ingestion pipeline
|
||||
- Generates vector embeddings (Qdrant)
|
||||
- Extracts entities (Neo4j)
|
||||
- **Bidirectional entity linking**:
|
||||
- New page links to existing entities
|
||||
- Existing entity pages link back to new page
|
||||
|
||||
### ✅ 2. **Page Updates** (`page.update`)
|
||||
- Re-ingests page with force refresh
|
||||
- Updates vector embeddings
|
||||
- Refreshes entity extraction
|
||||
- **Re-applies bidirectional linking**
|
||||
|
||||
### ✅ 3. **Page Deletion** (`page.delete`)
|
||||
**Comprehensive cleanup:**
|
||||
- ✅ Removes vector embeddings from Qdrant
|
||||
- ✅ Identifies orphaned entities (only mentioned in deleted page)
|
||||
- ✅ Deletes Document node from Neo4j
|
||||
- ✅ Deletes orphaned entities
|
||||
- ✅ Cleans up broken `MENTIONS` relationships
|
||||
- ✅ Cleans up broken `SearchQuery` relationships
|
||||
|
||||
### ✅ 4. **Page Rename/Move** (`page.rename`)
|
||||
**Intelligent handling:**
|
||||
- ✅ Updates Document node path in Neo4j
|
||||
- ✅ Updates title in Neo4j
|
||||
- **Path-only change** (move): Quick path update, no re-processing
|
||||
- **Title change** (rename): Full re-processing + entity relinking

## How It Works
|
||||
|
||||
### Architecture
|
||||
|
||||
```
|
||||
┌─────────────┐
|
||||

│ └─ Wiki.js (entity links in MD) │
|
||||
└───────────────────────────────────┘
|
||||
```
|
||||
|
||||
### Event Processing Flow
|
||||
|
||||
**1. Page Create/Update**
|
||||
```
|
||||
Webhook received → Extract user from email → Background task:
|
||||
├─ Ingest page (embeddings + entities)
|
||||
├─ Apply forward entity linking
|
||||
├─ Find reverse references
|
||||
└─ Apply backward entity linking
|
||||
```
|
||||
|
||||
**2. Page Delete**
|
||||
```
|
||||
Webhook received → Background task:
|
||||
├─ Remove vectors from Qdrant
|
||||
├─ Find orphaned entities
|
||||
├─ Delete Document node (cascades MENTIONS)
|
||||
├─ Delete orphaned entities
|
||||
└─ Clean broken SearchQuery relationships
|
||||
```
|
||||
|
||||
**3. Page Rename/Move**
|
||||
```
|
||||
Webhook received → Check what changed:
|
||||
├─ Path only? → Update Document.path
|
||||
└─ Title changed? → Re-ingest + re-link entities
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration Required
|
||||
|
||||
### Step 1: Wiki.js Webhook Setup
|
||||
|
||||
Navigate to **Administration** → **Webhooks** → **Add Webhook**
|
||||
|
||||
| Setting | Value |
|
||||
|---------|-------|
|
||||
| Endpoint URL | `http://library-desk:8089/webhooks/wikijs` |
|
||||
| Events | ☑ page.create, page.update, page.delete, page.rename |
|
||||
| Authorization | `Bearer af88ed8f44bed81bdb20d0534f1c4547340b29e2aba4963f61a71b993d7eb6e5` |
|
||||
|
||||
### Step 2: Deploy Updated Code
|
||||
|
||||
```bash
|
||||
cd services/library-desk
|
||||
docker-compose up -d --build library-desk
|
||||
```
|
||||
|
||||
### Step 3: Verify Webhook Endpoint
|
||||
|
||||
```bash
|
||||
curl http://192.168.86.149:8089/webhooks/health
|
||||
|
||||
# Expected response:
|
||||
# {"status": "ok", "service": "webhooks"}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing the Webhook
|
||||
|
||||
### Test 1: Create Page
|
||||
1. Create new page in Wiki.js: "Test Entity Linking"
|
||||
2. Add content: "This page discusses Docker and Kubernetes orchestration"
|
||||
3. Save page
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors created in Qdrant
|
||||
- Document node created in Neo4j with entities: Docker, Kubernetes
|
||||
- "Docker" and "Kubernetes" become hyperlinks (if entities exist)
|
||||
- Pages about Docker/Kubernetes now link back to this page
|
||||
|
||||
### Test 2: Update Page
|
||||
1. Edit the page
|
||||
2. Add: "We also use Terraform for infrastructure"
|
||||
3. Save
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors updated
|
||||
- "Terraform" entity extracted
|
||||
- "Terraform" becomes hyperlink
|
||||
- Terraform entity page links back to this page
|
||||
|
||||
### Test 3: Delete Page
|
||||
1. Delete the page from Wiki.js
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors removed from Qdrant
|
||||
- Document node removed from Neo4j
|
||||
- If "Test Entity Linking" was the only page mentioning an entity, that entity is deleted (orphan cleanup)
|
||||
|
||||
### Test 4: Move Page
|
||||
1. Create page at `/tech/docker-guide`
|
||||
2. Move to `/infrastructure/docker-guide`
|
||||
|
||||
**Expected Result:**
|
||||
- Document.path updated to `/infrastructure/docker-guide`
|
||||
- No re-processing (vectors/entities unchanged)
|
||||
- Links remain valid
|
||||
|
||||
### Test 5: Rename Page
|
||||
1. Create page "Docker Guide"
|
||||
2. Rename to "Docker Best Practices"
|
||||
|
||||
**Expected Result:**
|
||||
- Document.title updated
|
||||
- Full re-processing (title is entity-relevant)
|
||||
- Entity linking refreshed
|
||||
|
||||
---
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Response Times
|
||||
- **Webhook acknowledgment**: <100ms (non-blocking)
|
||||
- **Background processing**: 2-10s depending on page size
|
||||
- **No impact on Wiki.js editing experience**
|
||||
|
||||
### Resource Usage
|
||||
Per page edit:
|
||||
- **Ollama**: 1-2 embedding calls (~500ms each)
|
||||
- **Neo4j**: 3-5 queries (~100ms total)
|
||||
- **Qdrant**: 1 upsert operation (~50ms)
|
||||
- **Wiki.js**: 1-N page updates for backward links
|
||||
|
||||
### Scaling Considerations
|
||||
- Background tasks run asynchronously (non-blocking)
|
||||
- For bulk operations (>100 pages), consider:
|
||||
1. Temporarily disable webhook
|
||||
2. Use batch ingestion endpoint
|
||||
3. Re-enable webhook after bulk import
|
||||

|
||||
|
||||
## Monitoring & Debugging
|
||||
|
||||
### Check Webhook Activity
|
||||
|
||||
```bash
|
||||
# Watch webhook logs
|
||||
docker logs library-desk --follow | grep webhook
|
||||
|
||||
# Look for:
|
||||
# - "Received Wiki.js webhook: page.create"
|
||||
# - "Processing page.update for page 123"
|
||||
# - "Entity linking complete: 5 forward links, 3 backward links"
|
||||
# - "Cleanup complete for deleted page 456"
|
||||
```
|
||||
|
||||
### Verify Processing Complete
|
||||
|
||||
```bash
|
||||
# Check if page was indexed
|
||||
curl -X POST http://192.168.86.149:8089/query/hybrid \
|
||||
-H "Authorization: Bearer $API_KEY" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"query": "your page content", "user": "jpmschweitzer"}'
|
||||
|
||||
# Check graph entities
|
||||
# In Neo4j Browser:
|
||||
MATCH (d:Document {page_id: 123})-[:MENTIONS]->(e)
|
||||
RETURN d.title, collect(e.name) as entities
|
||||
```
|
||||
|
||||
### Common Issues & Solutions
|
||||
|
||||
**Problem:** Webhook not triggering
|
||||
- ✅ Check Wiki.js webhook configuration
|
||||
- ✅ Verify library-desk is running
|
||||
- ✅ Check authorization header
|
||||
|
||||
**Problem:** Processing fails silently
|
||||
- ✅ Check library-desk logs: `docker logs library-desk`
|
||||
- ✅ Verify Neo4j/Qdrant/Ollama are accessible
|
||||
- ✅ Check user email mapping in `extract_user_from_email()`
|
||||
|
||||
**Problem:** Orphaned entities remain after deletion
|
||||
- ✅ Orphan detection only removes entities with ZERO `MENTIONS` relationships
|
||||
- ✅ If entity is mentioned in other pages, it's preserved (correct behavior)
|
||||
|
||||
---
|
||||
|
||||
## Advanced Customization
|
||||
|
||||
### 1. Custom User Mapping
|
||||
|
||||
Edit `src/routers/webhooks.py`:
|
||||
|
||||
```python
|
||||
def extract_user_from_email(email: str) -> str:
|
||||
"""Map Wiki.js user emails to library-desk users"""
|
||||
user_map = {
|
||||
"admin@example.com": "admin",
|
||||
"john@example.com": "jpmschweitzer"
|
||||
}
|
||||
return user_map.get(email, email.split("@")[0])
|
||||
```
|
||||
|
||||
### 2. Selective Processing
|
||||
|
||||
Process only specific paths:
|
||||
|
||||
```python
|
||||
# In handle_wikijs_webhook():
|
||||
page_path = payload.page.get("path", "")
|
||||
if not page_path.startswith("/tech/"):
|
||||
logger.info(f"Skipping page outside /tech/")
|
||||
return
|
||||
```
|
||||
|
||||
### 3. Disable Backward Linking
|
||||
|
||||
To save processing time, disable backward linking:
|
||||
|
||||
```python
|
||||
# In process_wiki_page_change():
|
||||
# Comment out:
|
||||
# link_stats = await consolidation_service._apply_bidirectional_entity_linking(...)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Success Criteria
|
||||
|
||||
✅ **User-edited pages** have vectors in Qdrant
|
||||
✅ **User-edited pages** have entities in Neo4j
|
||||
✅ **User-edited pages** have bidirectional entity links
|
||||
✅ **Deleted pages** are cleaned from vectors + graph
|
||||
✅ **Renamed/moved pages** update correctly
|
||||
✅ **No difference** between manual and AI-generated pages
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Deploy the code** (restart library-desk)
|
||||
2. **Configure Wiki.js webhook** (Administration → Webhooks)
|
||||
3. **Test with a sample page** (create, edit, delete)
|
||||
4. **Monitor logs** (verify processing completes)
|
||||
5. **Verify results** (check vectors, graph, entity links)
|
||||
|
||||
---
|
||||
|
||||
## Summary
|
||||
|
||||
**Before webhooks:**
|
||||
- Only AI-generated pages fully integrated
|
||||
- Manual edits not indexed/linked
|
||||
- Inconsistent knowledge base
|
||||
|
||||
**After webhooks:**
|
||||
- **All pages processed identically**
|
||||
- **Automatic entity extraction**
|
||||
- **Bidirectional linking**
|
||||
- **Clean deletion handling**
|
||||
- **Rename/move support**
|
||||
|
||||
**Result:** A unified, consistent knowledge base regardless of content source! 🎉

# Wiki.js Webhook Setup Guide
|
||||
|
||||
Complete guide to enable automatic processing of user-edited wiki pages.
|
||||
|
||||
## Overview
|
||||
|
||||
When you manually edit pages in Wiki.js, the webhook system ensures they're processed identically to AI-generated content:
|
||||
|
||||
- ✅ **Vectors updated** - Qdrant embeddings refreshed
|
||||
- ✅ **Graph updated** - Entities extracted, relationships created
|
||||
- ✅ **Bidirectional links** - Automatic entity linking both ways
|
||||
- ✅ **Deletions handled** - Clean removal from vectors + graph
|
||||
- ✅ **Moves processed** - Path updates propagated to graph
|
||||
|
||||
## Step 1: Configure Wiki.js Webhook
|
||||
|
||||
### Access Wiki.js Administration
|
||||
|
||||
1. Log into Wiki.js as administrator
|
||||
2. Navigate to **Administration** → **Webhooks**
|
||||
3. Click **Add New Webhook**
|
||||
|
||||
### Webhook Configuration
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Name** | Library Desk Integration |
|
||||
| **Endpoint URL** | `http://library-desk:8089/webhooks/wikijs` |
|
||||
| **Content Type** | `application/json` |
|
||||
| **Events** | ☑ page.create<br>☑ page.update<br>☑ page.delete<br>☑ page.rename |
|
||||
| **Status** | ✅ Active |
|
||||
|
||||
### Authentication Header
|
||||
|
||||
Add custom header for API authentication:
|
||||
|
||||
```
|
||||
Authorization: Bearer af88ed8f44bed81bdb20d0534f1c4547340b29e2aba4963f61a71b993d7eb6e5
|
||||
```
|
||||
|
||||
*(Use your actual Library Desk API key from `.env`)*
|
||||
|
||||
## Step 2: Verify Webhook Endpoint
|
||||
|
||||
Test the webhook health endpoint:
|
||||
|
||||
```bash
|
||||
curl http://192.168.86.149:8089/webhooks/health
|
||||
```
|
||||
|
||||
Expected response:
|
||||
```json
|
||||
{
|
||||
"status": "ok",
|
||||
"service": "webhooks"
|
||||
}
|
||||
```
|
||||
|
||||
## Step 3: Test Webhook Integration
|
||||
|
||||
### Test 1: Page Creation
|
||||
|
||||
1. Create a new page in Wiki.js
|
||||
2. Add content mentioning existing entities (e.g., "Docker", "Kubernetes")
|
||||
3. Save the page
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors created in Qdrant
|
||||
- Document node created in Neo4j
|
||||
- Entities extracted and linked
|
||||
- Bidirectional links added (new page links to entities, entities' pages link back)
|
||||
|
||||
### Test 2: Page Update
|
||||
|
||||
1. Edit an existing page
|
||||
2. Add new content with entity mentions
|
||||
3. Save changes
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors updated in Qdrant (old removed, new added)
|
||||
- Graph updated with new entities
|
||||
- Entity links refreshed
|
||||
|
||||
### Test 3: Page Deletion
|
||||
|
||||
1. Delete a page from Wiki.js
|
||||
|
||||
**Expected Result:**
|
||||
- Vectors removed from Qdrant
|
||||
- Document node removed from Neo4j
|
||||
- Orphaned entities cleaned up (entities only mentioned in this page)
|
||||
- Broken relationships removed
|
||||
|
||||
### Test 4: Page Move/Rename
|
||||
|
||||
1. Move a page to different location (e.g., `/tech/docker` → `/infrastructure/docker`)
|
||||
2. Or rename the page
|
||||
|
||||
**Expected Result:**
|
||||
- Document node path updated in Neo4j
|
||||
- Entity links updated if title changed
|
||||
- Vectors remain valid (no re-embedding needed unless content changed)
|
||||
|
||||
## Event Processing Details
|
||||
|
||||
### page.create
|
||||
|
||||
```

```
|
||||
|
||||
## Monitoring Webhook Activity
|
||||
|
||||
### Check Logs
|
||||
|
||||
```bash
|
||||
# Library Desk logs
|
||||
docker logs library-desk --follow | grep webhook
|
||||
|
||||
# Look for:
|
||||
# - "Received Wiki.js webhook: page.create"
|
||||
# - "Processing page.update for page 123"
|
||||
# - "Cleanup complete for deleted page 456"
|
||||
```
|
||||
|
||||
### Verify Processing
|
||||
|
||||
After making changes in Wiki.js, verify:
|
||||
|
||||
**1. Vectors Updated:**
|
||||
```bash
|
||||
curl -X POST http://192.168.86.149:8089/query/hybrid \
|
||||
-H "Authorization: Bearer $API_KEY" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"query": "your page content", "user": "jpmschweitzer"}'
|
||||
```
|
||||
|
||||
**2. Graph Updated:**
|
||||
```cypher
|
||||
// In Neo4j Browser
|
||||
MATCH (d:Document {page_id: 123})
|
||||
OPTIONAL MATCH (d)-[:MENTIONS]->(e)
|
||||
RETURN d, collect(e.name) as entities
|
||||
```
|
||||
|
||||
**3. Entity Links Added:**
|
||||
Visit the page in Wiki.js and verify entity names are hyperlinked.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Webhook Not Triggering
|
||||
|
||||
**Problem:** Changes in Wiki.js don't trigger processing
|
||||
|
||||
**Solutions:**
|
||||
1. Check webhook configuration in Wiki.js Admin
|
||||
2. Verify endpoint URL is correct: `http://library-desk:8089/webhooks/wikijs`
|
||||
3. Check authorization header is set
|
||||
4. Verify library-desk is running: `docker ps | grep library-desk`
|
||||
5. Check library-desk logs: `docker logs library-desk --tail 50`
|
||||
|
||||
### Processing Failures
|
||||
|
||||
**Problem:** Webhook triggers but processing fails
|
||||
|
||||
**Solutions:**
|
||||
1. Check library-desk logs for errors
|
||||
2. Verify Neo4j is accessible
|
||||
3. Verify Qdrant is accessible
|
||||
4. Check Ollama is running (for embeddings)
|
||||
5. Verify user mapping in `extract_user_from_email()`
|
||||
|
||||
### Orphaned Entities
|
||||
|
||||
**Problem:** Deleted pages leave entities behind
|
||||
|
||||
**Solution:**
|
||||
Manually clean orphaned entities:
|
||||
```cypher
|
||||
// Find orphaned entities (no MENTIONS relationships)
|
||||
MATCH (e:User_Jpmschweitzer)
|
||||
WHERE NOT e:Document
|
||||
AND NOT EXISTS {(d:Document)-[:MENTIONS]->(e)}
|
||||
DETACH DELETE e
|
||||
RETURN count(e) as deleted
|
||||
```
|
||||
|
||||
### Broken Links
|
||||
|
||||
**Problem:** Entity links broken after page moves
|
||||
|
||||
**Solution:**
|
||||
Re-run entity linking on all pages:
|
||||
```bash
|
||||
curl -X POST http://192.168.86.149:8089/entity-linking/link-all \
|
||||
-H "Authorization: Bearer $API_KEY" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"user": "jpmschweitzer"}'
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Background Processing
|
||||
|
||||
Webhook handler processes events in the background to avoid blocking Wiki.js:
|
||||
- Webhook response: <100ms (immediate acknowledgment)
|
||||
- Processing: 2-10s (runs asynchronously)
|
||||
- No impact on Wiki.js editing experience
|
||||
|
||||
### Rate Limiting
|
||||
|
||||
For bulk operations (importing many pages):
|
||||
- Consider temporarily disabling webhook
|
||||
- Use batch ingestion endpoint instead: `/ingest/batch`
|
||||
- Re-enable webhook after bulk import
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Custom User Mapping
|
||||
|
||||
By default, user is extracted from email (`user@domain` → `user`).
|
||||
|
||||
Customize in `/services/library-desk/src/routers/webhooks.py`:
|
||||
|
||||
```python
|
||||
def extract_user_from_email(email: str) -> str:
|
||||
# Option 1: Map specific emails to users
|
||||
user_map = {
|
||||
"admin@example.com": "admin",
|
||||
"john.doe@example.com": "jpmschweitzer"
|
||||
}
|
||||
return user_map.get(email, email.split("@")[0])
|
||||
```
|
||||
|
||||
### Event Filtering
|
||||
|
||||
To process only certain pages, add filtering in webhook handler:
|
||||
|
||||
```python
|
||||
# Only process pages in /tech/ path
|
||||
if not payload.page.get("path", "").startswith("/tech/"):
|
||||
logger.info(f"Skipping page outside /tech/: {payload.page.get('path')}")
|
||||
return
|
||||
```
|
||||
|
||||
### Disable Bidirectional Linking
|
||||
|
||||
To only do forward linking (page → entities) without backward linking:
|
||||
|
||||
Edit `process_wiki_page_change()`:
|
||||
```python
|
||||
# Comment out the bidirectional linking call
|
||||
# link_stats = await consolidation_service._apply_bidirectional_entity_linking(...)
|
||||
```
|
||||
|
||||
## Summary
|
||||
|
||||
With webhooks configured:
|
||||
|
||||
| User Action | Automatic Processing |
|
||||
|-------------|---------------------|
|
||||
| Create page | Ingest + entity link (bidirectional) |
|
||||
| Edit page | Re-ingest + refresh links |
|
||||
| Delete page | Clean vectors + graph + orphaned entities |
|
||||
| Move page | Update paths + refresh links |
|
||||

# Wiki.js Page Change Detection
|
||||
|
||||
Automatic processing system for user-edited Wiki.js pages using PostgreSQL database triggers.
|
||||
|
||||
## Overview
|
||||
|
||||
**Problem:** Wiki.js doesn't have built-in webhooks (feature is [planned but not released](https://requarks.canny.io/wiki/p/webhooks))
|
||||
|
||||
**Solution:** PostgreSQL NOTIFY/LISTEN triggers to detect page changes in real-time
|
||||
|
||||
When you manually edit pages in Wiki.js, the change detection system ensures they're processed identically to AI-generated content:
|
||||
|
||||
- ✅ **Vectors updated** - Qdrant embeddings refreshed
|
||||
- ✅ **Graph updated** - Entities extracted, relationships created
|
||||
- ✅ **Bidirectional links** - Automatic entity linking both ways
|
||||
- ✅ **Deletions handled** - Clean removal from vectors + graph
|
||||
|
||||
---
|
||||
|
||||
## How It Works
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ Wiki.js (User edits page) │
|
||||
└──────────────────┬──────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ PostgreSQL "pages" table │
|
||||
│ INSERT/UPDATE/DELETE triggers fire │
|
||||
└──────────────────┬──────────────────────────┘
|
||||
│ pg_notify('wiki_page_changes', ...)
|
||||
↓
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ library-desk WikiChangeListener │
|
||||
│ Receives notification via LISTEN │
|
||||
└──────────────────┬──────────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ Processing Pipeline (same as webhooks) │
|
||||
│ ├─ Ingest page (vectors + graph) │
|
||||
│ ├─ Extract entities │
|
||||
│ ├─ Forward linking (page → entities) │
|
||||
│ └─ Backward linking (entities → page) │
|
||||
└─────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**Key Components:**
|
||||
|
||||
1. **PostgreSQL Triggers** - Installed in Wiki.js database, emit NOTIFY events on page changes
|
||||
2. **WikiChangeListener** - Python service that LISTENs for notifications and processes changes
|
||||
3. **Processing Pipeline** - Same logic as webhook handler (uses `process_wiki_page_change()`)
|
||||
|
||||

|
||||
|
||||
## Setup Instructions
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Library-desk has network access to Wiki.js PostgreSQL database
|
||||
- Database user has `CREATE FUNCTION` and `CREATE TRIGGER` permissions
|
||||
|
||||
### Step 1: Configure Environment Variables
|
||||
|
||||
Add these to your `.env` file:
|
||||
|
||||
```bash
|
||||
# Wiki.js Database Configuration (for change detection)
|
||||
WIKIJS_DB_HOST=postgres # PostgreSQL host (usually same as Wiki.js)
|
||||
WIKIJS_DB_PORT=5432 # PostgreSQL port
|
||||
WIKIJS_DB_NAME=wiki # Wiki.js database name
|
||||
WIKIJS_DB_USER=wikijs # Database user (needs trigger permissions)
|
||||
WIKIJS_DB_PASSWORD=your_password # Database password
|
||||
```
|
||||
|
||||
### Step 2: Install Database Triggers
|
||||
|
||||
Run the setup script from within the library-desk container:
|
||||
|
||||
```bash
|
||||
# Enter the container
|
||||
docker exec -it library-desk bash
|
||||
|
||||
# Run trigger setup script
|
||||
cd /app
|
||||
python3 setup_wiki_triggers.py
|
||||
```
|
||||
|
||||
**Expected output:**
|
||||
```
|
||||
======================================================================
|
||||
Wiki.js Database Trigger Setup
|
||||
======================================================================
|
||||
|
||||
Connecting to Wiki.js database at postgres:5432
|
||||
Database: wiki
|
||||
User: wikijs
|
||||
|
||||
✓ Connected to Wiki.js database
|
||||
|
||||
Installing triggers...
|
||||
|
||||
✓ Triggers installed successfully:
|
||||
|
||||
- wiki_page_delete_trigger (DELETE)
|
||||
- wiki_page_insert_trigger (INSERT)
|
||||
- wiki_page_update_trigger (UPDATE)
|
||||
|
||||
======================================================================
|
||||
Setup complete!
|
||||
======================================================================
|
||||
|
||||
Next steps:
|
||||
1. Restart library-desk service to activate the listener
|
||||
2. Edit a page in Wiki.js to test
|
||||
3. Check library-desk logs for processing messages
|
||||
```
|
||||
|
||||
### Step 3: Restart Library-Desk
|
||||
|
||||
```bash
|
||||
docker restart library-desk
|
||||
```
|
||||
|
||||
**Check logs for successful startup:**
|
||||
```bash
|
||||
docker logs library-desk --tail 50 | grep -E "(Wiki.js change listener|wiki_page_changes)"
|
||||
```
|
||||
|
||||
You should see:
|
||||
```
|
||||
INFO - Starting Wiki.js database change listener
|
||||
INFO - Listening for Wiki.js page changes via PostgreSQL NOTIFY
|
||||
INFO - Wiki.js change listener started successfully
|
||||
```
|
||||
|
||||
### Step 4: Test the System
|
||||
|
||||
1. **Create a new page in Wiki.js**
|
||||
- Add content mentioning existing entities (e.g., "Docker", "Kubernetes")
|
||||
- Save the page
|
||||
|
||||
2. **Check library-desk logs:**
|
||||
```bash
|
||||
docker logs library-desk --follow | grep -E "(Received|Processing|Entity linking)"
|
||||
```
|
||||
|
||||
**Expected log output:**
|
||||
```
|
||||
INFO - Received INSERT notification for page 123 by user@example.com
|
||||
INFO - Processing page.create for page 123 ('Test Page')
|
||||
INFO - Ingesting page 123 into knowledge base
|
||||
INFO - Ingestion complete for page 123
|
||||
INFO - Applying bidirectional entity linking for page 123
|
||||
INFO - Entity linking complete for page 123: 5 forward links, 3 backward links (2 pages updated)
|
||||
INFO - Successfully processed page.create for page 123
|
||||
```
|
||||
|
||||
3. **Verify results:**
|
||||
- Check vectors in Qdrant
|
||||
- Check Neo4j for Document node and entities
|
||||
- Visit the page in Wiki.js - entities should be hyperlinked
|
||||

|
||||
|
||||
## Event Processing Details
|
||||
|
||||
### page.create (INSERT trigger)
|
||||
|
||||
```
|
||||
User creates page → PostgreSQL INSERT trigger fires
|
||||
├─ pg_notify('wiki_page_changes', 'INSERT:123:user@example.com')
|
||||
├─ WikiChangeListener receives notification
|
||||
├─ Ingest page (vector + graph)
|
||||
├─ Extract entities
|
||||
├─ Forward linking (page → entities)
|
||||
└─ Backward linking (entities → page)
|
||||
```
|
||||
|
||||
### page.update (UPDATE trigger)
|
||||
|
||||
```
|
||||
User edits page → PostgreSQL UPDATE trigger fires
|
||||
├─ pg_notify('wiki_page_changes', 'UPDATE:123:user@example.com')
|
||||
├─ WikiChangeListener receives notification
|
||||
├─ Re-ingest page (force refresh)
|
||||
├─ Update entities
|
||||
├─ Refresh forward links
|
||||
└─ Refresh backward links
|
||||
```
|
||||
|
||||
### page.delete (DELETE trigger)
|
||||
|
||||
```
|
||||
User deletes page → PostgreSQL DELETE trigger fires
|
||||
├─ pg_notify('wiki_page_changes', 'DELETE:123:user@example.com')
|
||||
├─ WikiChangeListener receives notification
|
||||
├─ Remove vectors from Qdrant
|
||||
├─ Find orphaned entities
|
||||
├─ Delete Document node
|
||||
├─ Delete orphaned entities
|
||||
└─ Clean broken relationships
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Check Listener Status
|
||||
|
||||
```bash
|
||||
# Check if listener is running
|
||||
docker logs library-desk --tail 50 | grep "Wiki.js change listener"
|
||||
|
||||
# Should show:
|
||||
# INFO - Wiki.js change listener started successfully
|
||||
# INFO - Listening for Wiki.js page changes via PostgreSQL NOTIFY
|
||||
```
|
||||
|
||||
### Monitor Page Changes
|
||||
|
||||
```bash
|
||||
# Watch for page change notifications
|
||||
docker logs library-desk --follow | grep -E "(Received.*notification|Processing page)"
|
||||
```
|
||||
|
||||
### Verify Trigger Installation
|
||||
|
||||
Connect to Wiki.js database and check:
|
||||
|
||||
```sql
|
||||
-- List installed triggers
|
||||
SELECT trigger_name, event_manipulation, event_object_table
|
||||
FROM information_schema.triggers
|
||||
WHERE event_object_table = 'pages'
|
||||
ORDER BY trigger_name;
|
||||
|
||||
-- Expected result:
|
||||
-- wiki_page_delete_trigger | DELETE | pages
|
||||
-- wiki_page_insert_trigger | INSERT | pages
|
||||
-- wiki_page_update_trigger | UPDATE | pages
|
||||
```
|
||||
|
||||
### Test Notification Manually
|
||||
|
||||
You can manually test the NOTIFY/LISTEN system:
|
||||
|
||||
```sql
|
||||
-- In one session, listen for notifications:
|
||||
LISTEN wiki_page_changes;
|
||||
|
||||
-- In another session, manually trigger:
|
||||
NOTIFY wiki_page_changes, 'TEST:999:test@example.com';
|
||||
|
||||
-- The first session should receive the notification
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Change Listener Not Starting
|
||||
|
||||
**Problem:** Logs show "Failed to start Wiki.js change listener"
|
||||
|
||||
**Solutions:**
|
||||
1. Check database connection settings in `.env`
|
||||
2. Verify library-desk can reach Wiki.js PostgreSQL:
|
||||
```bash
|
||||
docker exec library-desk ping postgres
|
||||
```
|
||||
3. Test database credentials:
|
||||
```bash
|
||||
docker exec library-desk psql -h postgres -U wikijs -d wiki -c "\dt"
|
||||
```
|
||||
|
||||
### Changes Not Being Processed
|
||||
|
||||
**Problem:** Pages edited but no processing logs appear
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Check triggers are installed:**
|
||||
```bash
|
||||
docker exec -it postgres psql -U wikijs -d wiki -c "
|
||||
SELECT trigger_name FROM information_schema.triggers
|
||||
WHERE event_object_table = 'pages';
|
||||
"
|
||||
```
|
||||
|
||||
2. **Verify listener is running:**
|
||||
```bash
|
||||
docker logs library-desk | grep "Listening for Wiki.js page changes"
|
||||
```
|
||||
|
||||
3. **Test notification manually:**
|
||||
```bash
|
||||
docker exec -it postgres psql -U wikijs -d wiki -c "
|
||||
NOTIFY wiki_page_changes, 'INSERT:123:test@example.com';
|
||||
"
|
||||
```
|
||||
Check library-desk logs for "Received INSERT notification"
|
||||
|
||||
4. **Check authorEmail field exists:**
|
||||
The triggers use `authorEmail` field from Wiki.js pages table. Verify:
|
||||
```sql
|
||||
SELECT column_name
|
||||
FROM information_schema.columns
|
||||
WHERE table_name = 'pages' AND column_name = 'authorEmail';
|
||||
```
|
||||
|
||||
### Trigger Permission Denied
|
||||
|
||||
**Problem:** Setup script fails with "permission denied to create trigger"
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. Grant necessary permissions to database user:
|
||||
```sql
|
||||
GRANT CREATE ON DATABASE wiki TO wikijs;
|
||||
ALTER TABLE pages OWNER TO wikijs;
|
||||
```
|
||||
|
||||
2. Or run setup script with database admin user:
|
||||
```bash
|
||||
# Modify WIKIJS_DB_USER temporarily to postgres
|
||||
WIKIJS_DB_USER=postgres python3 setup_wiki_triggers.py
|
||||
```
|
||||
|
||||
### Processing Errors
|
||||
|
||||
**Problem:** Notification received but processing fails
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. Check library-desk logs for specific error:
|
||||
```bash
|
||||
docker logs library-desk --tail 100 | grep -A 10 "Failed to handle notification"
|
||||
```
|
||||
|
||||
2. Verify user mapping works:
|
||||
- Triggers extract user from `authorEmail` field
|
||||
- Check `extract_user_from_email()` in `wiki_change_listener.py`
|
||||
- Default: `user@domain.com` → `user`
|
||||
|
||||
3. Ensure page_id exists and is accessible
|
||||
|
||||
---
|
||||
|
||||
## User Mapping
|
||||
|
||||
By default, the user is extracted from the Wiki.js `authorEmail` field:
|
||||
|
||||
```python
|
||||
# user@example.com → user
|
||||
user = user_email.split('@')[0]
|
||||
```
|
||||
|
||||
**Custom mapping:** Edit `src/services/wiki_change_listener.py`:
|
||||
|
||||
```python
|
||||
async def _handle_notification(self, connection, pid, channel, payload):
|
||||
# ... existing code ...
|
||||
|
||||
# Custom user mapping
|
||||
user_map = {
|
||||
"admin@example.com": "admin",
|
||||
"john.doe@example.com": "jpmschweitzer"
|
||||
}
|
||||
user = user_map.get(user_email, user_email.split('@')[0])
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Comparison: Webhooks vs Database Triggers
|
||||
|
||||
| Feature | Webhooks (Not Available) | PostgreSQL Triggers |
|
||||
|---------|-------------------------|---------------------|
|
||||
| **Availability** | Planned, not released | Available now |
|
||||
| **Setup** | Simple (UI configuration) | Requires database access |
|
||||
| **Reliability** | HTTP-based, can fail | Database-native, highly reliable |
|
||||
| **Performance** | Network overhead | Minimal overhead |
|
||||
| **Maintenance** | None | Must survive database migrations |
|
||||
| **Isolation** | Loose coupling | Tight coupling to database |
|
||||
|
||||
**Recommendation:** Use database triggers until Wiki.js webhooks are officially released. When webhooks become available, migrate to that approach for better isolation.
|
||||
|
||||
---
|
||||
|
||||
## Uninstalling
|
||||
|
||||
To remove the triggers (if switching to webhooks later):
|
||||
|
||||
```bash
|
||||
docker exec -it postgres psql -U wikijs -d wiki -c "
|
||||
DROP TRIGGER IF EXISTS wiki_page_insert_trigger ON pages;
|
||||
DROP TRIGGER IF EXISTS wiki_page_update_trigger ON pages;
|
||||
DROP TRIGGER IF EXISTS wiki_page_delete_trigger ON pages;
|
||||
DROP FUNCTION IF EXISTS notify_page_change();
|
||||
"
|
||||
```
|
||||
|
||||
Then remove the listener startup from `src/main.py` (lines 354-364).
|
||||
|
||||

|
||||
|
||||
## Summary
|
||||
|
||||
With database triggers configured:
|
||||
|
||||
| User Action | Automatic Processing |
|
||||
|-------------|---------------------:|
|
||||
| Create page | Ingest + entity link (bidirectional) |
|
||||
| Edit page | Re-ingest + refresh links |
|
||||
| Delete page | Clean vectors + graph + orphaned entities |
|
||||
|
||||
**Result:** User-edited and AI-generated pages are **indistinguishable** in the knowledge base!

## Future: Migration to Webhooks
|
||||
|
||||
When Wiki.js webhooks are released:
|
||||
|
||||
1. Configure webhook in Wiki.js admin panel
|
||||
2. Point to `http://library-desk:8089/webhooks/wikijs`
|
||||
3. Remove database triggers (see Uninstalling section)
|
||||
4. Disable listener startup in `src/main.py`
|
||||
|
||||
The webhook handler already exists and uses the same processing logic!
