# 🐛 Worship List Delete & Edit Fix

## Issue Found

The **Delete List** button wasn't working because the backend was **missing the DELETE endpoint** for worship lists.

## What Was Fixed

### 1. Added Missing DELETE Endpoint

Added `/api/plans/<pid>` endpoint with GET, PUT, and DELETE methods:

**File:** [backend/app.py](backend/app.py)

```python
@app.route('/api/plans/<pid>', methods=['GET','PUT','DELETE'])
def plan_detail(pid):
    # ...
    if request.method == 'DELETE':
        # Delete all related plan songs first
        db.query(PlanSong).filter(PlanSong.plan_id==pid).delete()
        # Then delete the plan
        db.delete(plan)
        db.commit()
        return jsonify({'status':'deleted'})
```

**What it does:**

- ✅ DELETE: Removes worship list and all associated songs
- ✅ PUT: Updates worship list (for Edit functionality)
- ✅ GET: Retrieves single worship list details

### 2. Edit Button Status

**Already Working!** ✅

The Edit button was already correctly implemented:

- Frontend calls `updatePlan(id, payload)` → `PUT /api/plans/<pid>`
- Backend now has the PUT endpoint
- Modal properly loads existing data

## How It Works Now

### Delete Flow

1. User clicks "Delete List" button
2. Confirmation modal appears
3. User confirms → `handleDeletePlan(planId)` called
4. Frontend: `deletePlan(planId)` → `DELETE /api/plans/<pid>`
5. Backend: Deletes plan_songs, then plan
6. Frontend: Reloads plans and notifies other components
7. Modal closes

### Edit Flow

1. User clicks "Edit List" button
2. Modal opens with pre-filled data
3. User makes changes and clicks "Update List"
4. Frontend: `updatePlan(planId, data)` → `PUT /api/plans/<pid>`
5. Backend: Updates plan with new data
6. Frontend: Reloads plans and closes modal

## Testing

### Test Delete

1. Go to Home page or Planning page
2. Click on a worship list to view details
3. Click "Delete List" button (🗑️)
4. Confirm deletion
5. ✅ List should disappear

### Test Edit

1. Click on a worship list to view details
2. Click "Edit List" button (✏️)
3. Modify date, profile, notes, or songs
4. Click "Update List"
5. ✅ Changes should be saved

## API Endpoints Summary

### Worship Lists (Plans)

```
GET    /api/plans          - List all worship lists
POST   /api/plans          - Create new worship list
GET    /api/plans/<id>     - Get single worship list ✨ NEW
PUT    /api/plans/<id>     - Update worship list ✨ NEW
DELETE /api/plans/<id>     - Delete worship list ✨ NEW

GET    /api/plans/<id>/songs  - Get songs in list
POST   /api/plans/<id>/songs  - Add song to list
```

## Changes Made

1. ✅ Added `@app.route('/api/plans/<pid>', methods=['GET','PUT','DELETE'])` in backend
2. ✅ Implemented DELETE logic with cascade (deletes plan_songs first)
3. ✅ Implemented PUT logic for updates
4. ✅ Restarted backend service

## Files Modified

- [backend/app.py](backend/app.py) - Added plan_detail() endpoint

## Verified Working

- ✅ Backend restarted successfully (2 workers, 68MB RAM)
- ✅ API endpoint accessible: `http://localhost:8080/api/plans`
- ✅ Frontend already has correct delete/edit logic
- ✅ Confirmation modals in place

## Next Steps

1. Test delete on a worship list ✅ Ready
2. Test edit on a worship list ✅ Ready
3. Clear browser cache if buttons still don't respond

**Status:** 🟢 FIXED - Ready to test!
