## Current Database Storage (OnboardingDatabaseService)

### What's Saved to `onboarding_sessions.website_analyses` Table:

**File**: `backend/services/onboarding_database_service.py` (Line 173)

```python
WebsiteAnalysis(
    session_id=session.id,
    website_url=analysis_data.get('website_url'),
    writing_style=analysis_data.get('writing_style'),              # ✅
    content_characteristics=analysis_data.get('content_characteristics'),  # ✅
    target_audience=analysis_data.get('target_audience'),          # ✅
    content_type=analysis_data.get('content_type'),                # ✅
    recommended_settings=analysis_data.get('recommended_settings'),# ✅
    crawl_result=analysis_data.get('crawl_result'),                # ✅
    style_patterns=analysis_data.get('style_patterns'),            # ✅
    style_guidelines=analysis_data.get('style_guidelines'),        # ✅
    status='completed'
)
```

### ❌ What's MISSING from Database Storage:

1. **brand_analysis** - NOT saved to `onboarding_database_service`
2. **content_strategy_insights** - NOT saved to `onboarding_database_service`

### ✅ What's Saved to `website_analyses` Table (via WebsiteAnalysisService):

**File**: `backend/services/website_analysis_service.py` (Lines 44-87)

This service saves to a DIFFERENT table (`website_analyses` not `onboarding_sessions.website_analyses`).

```python
# Saves to: website_analyses table
WebsiteAnalysis(
    session_id=session_id,                    # Integer session ID
    website_url=website_url,
    writing_style=style_analysis.get('writing_style'),
    content_characteristics=style_analysis.get('content_characteristics'),
    target_audience=style_analysis.get('target_audience'),
    content_type=style_analysis.get('content_type'),
    recommended_settings=style_analysis.get('recommended_settings'),
    brand_analysis=style_analysis.get('brand_analysis'),           # ✅ SAVED HERE!
    content_strategy_insights=style_analysis.get('content_strategy_insights'),  # ✅ SAVED HERE!
    crawl_result=analysis_data.get('crawl_result'),
    style_patterns=analysis_data.get('style_patterns'),
    style_guidelines=analysis_data.get('style_guidelines'),
    status='completed'
)
```

## The Problem: Dual Database Persistence

We have **TWO separate database save operations** happening:

### 1. `/style-detection/complete` endpoint (component_logic.py)
- Saves to `website_analyses` table via `WebsiteAnalysisService`
- Uses **Integer session_id** (converted from Clerk ID via SHA256)
- Saves **ALL fields** including `brand_analysis` and `content_strategy_insights`

### 2. `OnboardingProgress.save_progress()` (api_key_manager.py)
- Saves to `onboarding_sessions.website_analyses` table via `OnboardingDatabaseService`
- Uses **String user_id** (Clerk ID)
- **MISSING** `brand_analysis` and `content_strategy_insights`

## Current Frontend Data Structure

**File**: `frontend/src/components/OnboardingWizard/WebsiteStep.tsx` (Line 386)

```typescript
const stepData = {
  website: fixedUrl,              // ← Should be "website_url"
  domainName: domainName,
  analysis: {                     // ← Nested structure
    writing_style: {...},
    content_characteristics: {...},
    target_audience: {...},
    content_type: {...},
    brand_analysis: {...},        // ✅ Present
    content_strategy_insights: {...},  // ✅ Present
    recommended_settings: {...},
    // ... ALL the fields from API response
    guidelines: [...],
    best_practices: [...],
    avoid_elements: [...],
    style_patterns: {...},
    // etc.
  },
  useAnalysisForGenAI: true
};
```

## Solution Required

### 1. Fix Data Transformation (COMPLETED ✅)

**File**: `backend/services/api_key_manager.py` (Line 278)

Already fixed to flatten the structure:

```python
elif step.step_number == 2:  # Website Analysis
    # Transform frontend data structure to match database schema
    analysis_for_db = {
        'website_url': step.data.get('website', ''),
        'status': 'completed'
    }
    # Merge analysis fields if they exist
    if 'analysis' in step.data and step.data['analysis']:
        analysis_for_db.update(step.data['analysis'])
    
    self.db_service.save_website_analysis(self.user_id, analysis_for_db, db)
```

### 2. Update OnboardingDatabaseService to Save ALL Fields

**File**: `backend/services/onboarding_database_service.py`

**NEEDED**: Add `brand_analysis` and `content_strategy_insights` to the save operation.

Check if `WebsiteAnalysis` model has these columns:

```python
# Line 206-213 (existing code)
website_url=analysis_data.get('website_url', ''),
writing_style=analysis_data.get('writing_style'),
content_characteristics=analysis_data.get('content_characteristics'),
target_audience=analysis_data.get('target_audience'),
content_type=analysis_data.get('content_type'),
recommended_settings=analysis_data.get('recommended_settings'),
brand_analysis=analysis_data.get('brand_analysis'),              # ← ADD THIS
content_strategy_insights=analysis_data.get('content_strategy_insights'),  # ← ADD THIS
crawl_result=analysis_data.get('crawl_result'),
style_patterns=analysis_data.get('style_patterns'),
style_guidelines=analysis_data.get('style_guidelines'),
```

### 3. Verify Database Model Supports These Fields

**File**: `backend/models/onboarding.py`

Check `WebsiteAnalysis` model for:
- `brand_analysis` column (JSON)
- `content_strategy_insights` column (JSON)

If missing, add migration.

## Recommendation

1. ✅ **Data transformation fix is complete** (api_key_manager.py updated)
2. ⏳ **Check WebsiteAnalysis model** for brand_analysis and content_strategy_insights columns
3. ⏳ **Update OnboardingDatabaseService.save_website_analysis()** to include these fields
4. ⏳ **Restart backend** to apply changes
5. ⏳ **Re-run Step 2** to save complete data
6. ⏳ **Verify Step 6** displays all fields

## Benefits of Complete Data Storage

With `brand_analysis` and `content_strategy_insights` saved:

1. **Better Content Generation**: AI can align with brand values
2. **Strategic Insights**: SWOT analysis informs content strategy
3. **Competitive Intelligence**: Differentiation factors for positioning
4. **Content Planning**: Recommendations and calendar suggestions
5. **Quality Assurance**: Consistency checking against brand guidelines

## Status

- ✅ API endpoint returns complete data
- ✅ Frontend receives and displays complete data
- ✅ Data transformation fix applied (flattening structure)
- ⏳ Database model verification needed
- ⏳ OnboardingDatabaseService update needed
- ⏳ Testing required

---

**Next Action**: Check `WebsiteAnalysis` model and update `OnboardingDatabaseService` to save ALL fields.
