# Migration Scripts Update Summary

**Date:** 2025-10-23
**Reason:** Fix post-migration bugs in network_devices.asp

---

## Root Cause

After running migration on fresh production database, discovered that:
1. Access Points were missing from `vw_network_devices` view
2. Camera-specific columns (`idfid`, `idfname`, `macaddress`) were missing from view
3. Access Points table was missing `apname` and `modelid` columns
4. **Printers were missing from `vw_network_devices` view** (discovered during final verification)

This caused network_devices.asp to fail when trying to display cameras (500 error) and printers not showing up in the network devices page.

## Files Updated

### 1. `sql/add_infrastructure_vendor_model_support.sql`

**Changes:**
- Added **SECTION 5**: Add modelid to accesspoints table
- Updated section numbering (SECTION 5 → SECTION 6, SECTION 6 → SECTION 7)
- Updated verification queries to include `accesspoints` table
- Added foreign key constraint for accesspoints.modelid → models

**New Steps:**
```
Step 5 Complete: Added modelid to accesspoints table
Step 6 Complete: Updated vw_network_devices with vendor/model info (was Step 5)
```

### 2. `sql/add_device_name_fields.sql`

**Changes:**
- Added **SECTION 4**: Add name field (apname) to accesspoints table
- Updated section numbering (SECTION 4 → SECTION 5, SECTION 5 → SECTION 6)
- **CRITICAL FIX**: Updated `vw_network_devices` view to include:
  - Camera-specific columns: `idfid`, `idfname`, `macaddress`
  - Access Points section (entire UNION ALL block)
  - **Printers section (entire UNION ALL block)**
  - All UNION sections now have same column structure
- Updated verification queries to include `accesspoints` table

**View Structure Now Includes:**
```sql
-- All sections now include these columns:
device_type, device_id, device_name,
modelid, modelnumber, vendor,
serialnumber, ipaddress, description,
maptop, mapleft, isactive,
idfid, idfname, macaddress  -- Camera-specific, NULL for others

-- Device types in view: IDF, Server, Switch, Camera, Access Point, Printer
```

**New Steps:**
```
Step 4 Complete: Added apname to accesspoints table
Step 5 Complete: Updated vw_network_devices view with name fields, camera columns, and printers (was Step 4)
```

### 3. `sql/PRODUCTION_MIGRATION_CHECKLIST.md`

**Changes:**
- Updated Script 1 expected output to show 6 steps (was 5)
- Added `accesspoints` to all verification queries
- Updated Script 2 expected output to show 5 steps (was 4)
- Updated verification examples to include `accesspoints | apname | varchar`
- Updated Final Schema Reference to include:
  - Complete accesspoints table schema
  - Camera-specific columns in vw_network_devices view

## Migration Impact

### Before Fix
- ❌ network_devices.asp?filter=Camera → 500 error
- ❌ Access Points not in vw_network_devices view
- ❌ Access Points missing apname and modelid columns
- ❌ Printers not in vw_network_devices view

### After Fix
- ✅ network_devices.asp?filter=Camera → Works correctly
- ✅ Access Points included in vw_network_devices view
- ✅ Access Points have apname and modelid columns
- ✅ Printers included in vw_network_devices view (40 printers displaying)
- ✅ All device types display correctly in network_devices.asp
- ✅ Camera IDF information displays properly

---

## Testing Performed

Tested on freshly imported production database (database-backup-10-23-25-updated.sql):

1. ✅ Ran all 3 migration scripts in sequence
2. ✅ Added Server with new vendor/model
3. ✅ Added Camera with new vendor/model/IDF
4. ✅ Added Access Point with new vendor/model
5. ✅ Verified network_devices.asp?filter=Camera works
6. ✅ Verified network_devices.asp?filter=Server works
7. ✅ Verified network_devices.asp?filter=Access Point works
8. ✅ Verified network_devices.asp?filter=Printer works (40 printers displaying)
9. ✅ Verified network_devices.asp?filter=all works

## Production Deployment Notes

**Safe to Re-run:** YES - All scripts use IF NOT EXISTS checks

**Backwards Compatible:** YES
- New columns are nullable
- Existing queries continue to work
- View changes are additive (more columns available)

**Breaking Changes:** NONE
- All changes are additive
- Existing functionality preserved
