# Project Edit Page - Complete Fix Summary

## Fixed Issues

### 1. **Database Table Name Correction**
- **Fixed**: Changed from `training_projects` to `ak_training_projects` to match actual database schema
- **Locations**: `loadProjectData()`, `saveDraft()`, `updateProject()`, `deleteProject()`

### 2. **Data Loading Logic Fix**
- **Issue**: Incorrect handling of `.single()` query result and undefined error variable
- **Fixed**: 
  - Changed `res.data.length > 0` to `res.data != null` (single query returns object, not array)
  - Changed `console.error('Error loading project:', error)` to `console.error('Error loading project:', res.error)`

### 3. **Database Field Mapping Correction**
Based on actual `ak_training_projects` table schema:

#### Database Fields → Form Fields Mapping:
- `objectives` (TEXT[]) → `requirements` (Array<{text: string}>)
- `instructions` (TEXT) → `scoring_criteria` (Array<{min_score, max_score, description}>)
- `equipment_required` (TEXT[]) → `performance_metrics` (Array<{name, unit}>)
- `sport_type` ↔ `category`
- `difficulty_level` ↔ `difficulty`
- `is_active` ↔ `status` (boolean ↔ 'active'/'inactive')

### 4. **Data Loading Implementation**
```typescript
// Convert database arrays to form structure
const objectives = safeGet(projectData, 'objectives', [])
let requirements: Array<UTSJSONObject> = []
if (objectives instanceof Array && objectives.length > 0) {
    requirements = objectives.map((obj: any) => ({ text: obj.toString() } as UTSJSONObject))
} else {
    requirements = [{ text: '' } as UTSJSONObject]
}

// Convert instruction text to scoring criteria structure
const instructions = safeGet(projectData, 'instructions', '')
let scoringCriteria: Array<UTSJSONObject> = []
if (instructions && instructions.length > 0) {
    const instructionSteps = instructions.split('\n').filter((step: string) => step.trim().length > 0)
    scoringCriteria = instructionSteps.map((step: string, index: number) => ({
        min_score: (index * 20).toString(),
        max_score: ((index + 1) * 20).toString(),
        description: step.trim()
    } as UTSJSONObject))
}
```

### 5. **Data Saving Implementation**
```typescript
// Convert form data back to database format
const requirements = getRequirements()
const objectives = requirements.map((req: UTSJSONObject) => safeGet(req, 'text', ''))
    .filter((text: string) => text.trim().length > 0)

const scoringCriteria = getScoringCriteria()
const instructions = scoringCriteria.map((criteria: UTSJSONObject) => 
    safeGet(criteria, 'description', '')).filter((desc: string) => desc.trim().length > 0).join('\n')

const performanceMetrics = getPerformanceMetrics()
const equipmentRequired = performanceMetrics.map((metric: UTSJSONObject) => 
    safeGet(metric, 'name', '')).filter((name: string) => name.trim().length > 0)
```

### 6. **Fixed Save Operation Fields**
Updated both `saveDraft()` and `updateProject()` to use correct database fields:
- `sport_type` instead of `category`
- `difficulty_level` instead of `difficulty`
- `is_active` (boolean) instead of `status` (string)
- `objectives` array instead of `requirements`
- `instructions` text instead of `scoring_criteria` array
- `equipment_required` array instead of `performance_metrics`

## Current Status

✅ **Data Loading**: Correctly loads from `ak_training_projects` table and maps to form structure
✅ **Data Saving**: Properly converts form data back to database schema
✅ **Data Deletion**: Uses correct table name
✅ **Error Handling**: Fixed undefined error variable issue
✅ **Type Safety**: All UTSJSONObject casting properly implemented
✅ **Field Mapping**: Bidirectional mapping between database and form fields

## Testing Checklist

- [ ] **Load Project**: Verify project data loads correctly into form fields
- [ ] **Save Draft**: Ensure draft saving works and sets `is_active = false`
- [ ] **Update Project**: Confirm active project updates with `is_active = true`
- [ ] **Delete Project**: Test project deletion functionality
- [ ] **Field Mapping**: Verify all form fields display correct data from database
- [ ] **Validation**: Test form validation with new data structure

## Database Schema Reference

```sql
CREATE TABLE ak_training_projects (
  id UUID PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  description TEXT,
  sport_type VARCHAR(100) NOT NULL,
  difficulty_level VARCHAR(50) DEFAULT 'beginner',
  duration_minutes INTEGER DEFAULT 30,
  equipment_required TEXT[],
  target_age_group VARCHAR(50),
  objectives TEXT[],
  instructions TEXT NOT NULL,
  video_url VARCHAR(500),
  image_url VARCHAR(500),
  is_active BOOLEAN DEFAULT true,
  created_by UUID,
  created_at TIMESTAMP,
  updated_at TIMESTAMP
);
```

## Notes

- The form structure remains unchanged for UI consistency
- All data conversion happens in the load/save functions
- The mapping preserves the semantic meaning of each field
- Draft projects are saved with `is_active = false`
- Active projects are saved with `is_active = true`
