# Creative X Mappings Guide

## Overview

The Ferrero naming convention and Creative X API use different codes and naming for brands, channels, and markets. This mapping system bridges the two systems to enable seamless uploads.

## Architecture

```
Ferrero Filename
       ↓
  [Filename Parser] → Extracts Ferrero codes
       ↓
  [Mapping Resolver] → Translates to Creative X format
       ↓
  [API Client] → Uploads with Creative X metadata
```

## Files

- **`mappings.json`** - Complete mapping tables (brands, channels, countries)
- **`core/mapping_resolver.py`** - Python module for resolving mappings
- **`scripts/upload.py`** - Upload script (uses mapping resolver)

---

## Mapping Tables

### 1. Brand Mappings

Maps Ferrero brand codes to Creative X brand names and IDs.

**Example:**
```json
{
  "NUT": {
    "creativex_name": "Nutella",
    "creativex_id": 423,
    "ferrero_name": "NUTELLA"
  },
  "RAF": {
    "creativex_name": "Rafalleo",
    "creativex_id": 422,
    "ferrero_name": "RAFFAELLO"
  }
}
```

**Current Status:**
- ✅ Nutella (NUT)
- ✅ Raffaello (RAF) - Note: Creative X spells it "Rafalleo"
- ❌ 103 other Ferrero brands not yet added to Creative X

### 2. Channel Mappings

Maps Ferrero social media codes to Creative X channel + publisher + placement combinations.

**Structure:**
```json
{
  "FERRERO_CODE": {
    "ferrero_name": "Human-readable name",
    "creativex_channel": "channel_name",
    "creativex_publisher": "publisher_name (optional)",
    "creativex_placement": "placement_name (optional)",
    "creativex_ad_format": "ad_format (optional for YouTube/DV360)"
  }
}
```

**Examples:**

#### Facebook (requires channel + publisher + placement)
```
FBS → facebook_paid / facebook / facebook_stories
IGF → instagram_paid / instagram / feed
```

#### YouTube (requires channel + publisher + ad_format)
```
YTB → google_ads / youtube / Bumper
YTS → google_ads / youtube / Shorts
```

#### Simple channels (only need channel name)
```
TIK → tiktok_paid
PIN → pinterest
```

**Supported Channels:**
| Ferrero Code | Creative X Channel | Notes |
|--------------|-------------------|-------|
| FBS, FBF, etc. | facebook_paid | 15 Facebook placements |
| IGF, IGR, IST, etc. | instagram_paid | 11 Instagram placements |
| MSI, MSS | facebook_paid | 2 Messenger placements |
| ANC, ANI, ANR | facebook_paid | 3 Audience Network placements |
| YTB, YTI, YTS, etc. | google_ads | 5 YouTube ad formats |
| DV3 | dv360 | Display & YouTube |
| TIK | tiktok_paid | TikTok |
| SNA | snapchat_paid | Snapchat |
| PIN | pinterest | Pinterest |
| TWI | twitter_paid | Twitter/X |
| AMZ | amazon_paid | Amazon |
| GOO | google_ads | Generic Google |

### 3. Country Mappings

Most country codes use standard ISO 3166-1 alpha-2 codes and map directly.

**Special Cases:**
- **GL** = "Global" (not Greenland) - Creative X expects `market_name: "Global"` with no ISO code
- **CZ** = Czechia (Ferrero may use "Czech Republic")
- **US** = "United States of America" (not just "United States")
- **GB** = "United Kingdom"
- **KR** = "South Korea"

All other countries use standard ISO codes (DE, IT, FR, ES, etc.)

## How It Works

### 1. Parsing Phase

```python
from core.filename_parser import FerreroFilenameParser

parser = FerreroFilenameParser(data_loader)
parsed = parser.parse("NUT_GL_en_MOMENT_OLV_6S_1x1_FBS_xyz.mp4")

# Result:
{
  'brand_code': 'NUT',
  'brand_name': 'NUTELLA',
  'country_code': 'GL',
  'country_name': 'GLOBAL',
  'language_code': 'en',
  'social_media': 'FBS',
  'channel': 'FB - Stories',
  ...
}
```

### 2. Mapping Phase

```python
from core.mapping_resolver import MappingResolver

resolver = MappingResolver('mappings.json')
creativex_payload = resolver.build_creativex_payload(parsed)

# Result:
{
  'brand_name': 'Nutella',
  'channel': 'facebook_paid',
  'publisher': 'facebook',
  'placement': 'facebook_stories',
  'market_name': 'Global',
  'language': 'en',
  'dimensions': '1x1',
  'duration': '6',
  ...
}
```

### 3. Upload Phase

```python
api_client.create_preflight({
  'name': 'NUT_GL_en_MOMENT_OLV_6S_1x1_FBS_xyz.mp4',
  'brand_name': 'Nutella',
  'market_name': 'Global',
  'channel': 'facebook_paid',
  'publisher': 'facebook',
  'placement': 'facebook_stories',
  'language': 'en',
  'dimensions': '1x1',
  'duration': '6',
  'creatives': [
    {'source_url': 'https://s3.../file.mp4'}
  ]
})
```

---

## Validation

The system validates at multiple levels:

### 1. Brand Validation
```python
resolver.is_brand_supported('NUT')  # True
resolver.is_brand_supported('ROC')  # False - not in Creative X yet
```

### 2. Channel Validation
```python
resolver.is_channel_supported('FBS')  # True
resolver.is_channel_supported('XXX')  # False - not mapped
```

### 3. Full Metadata Validation
```python
is_valid, errors = resolver.validate_metadata_for_upload(parsed_data)
if not is_valid:
    print("Errors:", errors)
```

---

## Adding New Mappings

### Add a New Brand

Edit `mappings.json`:

```json
{
  "brand_mappings": {
    "ROC": {
      "creativex_name": "Ferrero Rocher",
      "creativex_id": 424,
      "ferrero_name": "ROCHER"
    }
  }
}
```

**Steps:**
1. Get Creative X brand ID from `/dimensions` endpoint
2. Add mapping to `mappings.json`
3. Test upload: `python scripts/upload.py --dry-run test_file.mp4`

### Add a New Channel

Edit `mappings.json`:

```json
{
  "channel_mappings": {
    "NEW_PLATFORM_CODES": {
      "NPF": {
        "ferrero_name": "New Platform - Feed",
        "creativex_channel": "new_platform_paid",
        "creativex_publisher": "new_platform",
        "creativex_placement": "feed"
      }
    }
  }
}
```

**Steps:**
1. Query `/dimensions` to see Creative X channel structure
2. Determine if channel needs publisher/placement/ad_format
3. Add mapping following existing patterns
4. Test validation

## Common Issues & Solutions

### Issue: "Brand 'XXX' is not supported in Creative X"

**Cause:** Brand not yet added to Creative X system

**Solutions:**
1. Check if brand exists: `python get_dimensions.py | grep -i brandname`
2. If exists, add mapping to `mappings.json`
3. If doesn't exist, contact Creative X to add brand

### Issue: "Social media code 'XXX' not mapped"

**Cause:** Ferrero social code not in `mappings.json`

**Solutions:**
1. Check Creative X channels: `python get_dimensions.py`
2. Identify correct channel/publisher/placement
3. Add mapping to `mappings.json`

### Issue: "Invalid placement for channel"

**Cause:** Mismatch between channel and placement

**Solutions:**
1. Verify placement exists: `python get_dimensions.py`
2. Check channel structure (some channels need publisher+placement, others don't)
3. Update mapping with correct structure

### Issue: "Market not found"

**Cause:** Country code mapping issue (usually GL = Global)

**Solutions:**
1. Check if country exists: `python get_dimensions.py | grep -i country`
2. For "Global" uploads, ensure GL maps to market_name="Global" (no ISO code)
3. Update `country_mappings.SPECIAL_CASES` if needed

---

## Testing Mappings

### 1. Dry Run Test

Test mapping without uploading:

```bash
python scripts/upload.py --dry-run /path/to/test_file.mp4
```

**Expected output:**
```
✓ File valid
✓ Brand: NUTELLA
✓ Market: GLOBAL
✓ Channel: FB - Stories
✓ Metadata valid
✓ Mappings valid
  → Brand: Nutella
  → Channel: facebook_paid
  → Publisher: facebook
  → Placement: facebook_stories
✓ DRY RUN: Would upload file
```

### 2. Query Available Dimensions

Check what's available in Creative X:

```bash
source venv/bin/activate
python get_dimensions.py > dimensions_output.txt
```

Review:
- Available brands
- Available channels (with publishers/placements)
- Available markets

### 3. Interactive Python Test

```python
from core.mapping_resolver import MappingResolver

resolver = MappingResolver('mappings.json')

# Test brand
brand = resolver.get_creativex_brand('NUT')
print(f"Brand: {brand}")

# Test channel
channel = resolver.get_creativex_channel_mapping('FBS')
print(f"Channel: {channel}")

# Test market
market = resolver.get_creativex_market('GL')
print(f"Market: {market}")

# List all supported
print(f"Supported brands: {resolver.get_all_supported_brands()}")
print(f"Supported channels: {resolver.get_all_supported_channels()}")
```

### Upload Workflow
```
1. Parse filename → Extract Ferrero codes
2. Validate file → Check format/size
3. Validate Ferrero metadata → Check against data.json
4. Validate mappings → Check brand/channel exist in Creative X
5. Get presigned URL → From Creative X API
6. Upload to S3 → Direct to S3
7. Create preflight → With mapped metadata
```

## Support

**Issues:**
- Brand not mapped → Add to `brand_mappings` in `mappings.json`
- Channel not mapped → Add to `channel_mappings` in `mappings.json`

**Testing:**
```bash
# Test with dry run
python scripts/upload.py --dry-run file.mp4

# Check dimensions
python get_dimensions.py

# Check logs
cat data/logs/creativex_upload_*.log
