 DASHBOARD FIX - Events Table Structure Issue
================================================================================

ISSUE:
------
Fatal error: Column not found: 1054 Unknown column 'e.event_date' in 'where clause'

ROOT CAUSE:
-----------
The events table uses a different column structure than other tables:
- Uses 'start_date' and 'end_date' (NOT 'event_date')
- Uses 'location_type' and 'location_id' (NOT area_id/district_id/assembly_id)

SOLUTION APPLIED:
-----------------
Updated dashboard.php to handle events with custom filtering logic:

1. Fixed column name: event_date → start_date
2. Implemented custom access control for events based on location_type:
   - Assembly admin: location_type = 'assembly' AND location_id = user's assembly
   - District admin: location_type IN ('district', 'assembly') with proper filtering
   - Area admin: location_type IN ('area', 'district', 'assembly')

FILES MODIFIED:
---------------
✅ dashboard.php (lines 19-93)
   - Event count query with custom filtering
   - Upcoming events query with custom filtering

✅ ACCESS_CONTROL_IMPLEMENTATION.md
   - Added warning section about events table structure
   - Added example code for handling events

TABLE COMPARISON:
-----------------
Members Table:     area_id, district_id, assembly_id ✅ (Standard)
Programs Table:    area_id, district_id, assembly_id ✅ (Standard)
Ministries Table:  area_id, district_id, assembly_id ✅ (Standard)
Events Table:      location_type, location_id ❌ (Different structure)

TESTING:
--------
✅ Dashboard now loads without errors
✅ Event counts filtered by access level
✅ Upcoming events filtered by access level
✅ Other statistics (members, programs, ministries) work correctly

IMPORTANT NOTE:
---------------
When working with the events table in other modules:
- ALWAYS use start_date/end_date (not event_date)
- ALWAYS use custom filtering with location_type and location_id
- See dashboard.php lines 19-93 for reference implementation
