🎯 Usage Examples

Upload Photo (API)

curl -X POST http://localhost:8000/api/v1/photos/upload \
  -H "Authorization: Bearer {token}" \
  -F "file=@photo.jpg" \
  -F "title=Amazing Roller Coaster" \
  -F "photo_type=gallery" \
  -F "entity_type=park" \
  -F "entity_id={park_uuid}"

Get Entity Photos (API)

curl http://localhost:8000/api/v1/park/{park_id}/photos?photo_type=gallery

In Python Code

from apps.entities.models import Park
from apps.media.services import PhotoService

# Get a park
park = Park.objects.get(slug='cedar-point')

# Get photos
main_photo = park.main_photo
gallery = park.gallery_photos
all_photos = park.get_photos(approved_only=True)

# Upload programmatically
service = PhotoService()
photo = service.create_photo(
    file=uploaded_file,
    user=request.user,
    entity=park,
    photo_type='gallery'
)

📈 Performance Considerations

Optimizations Implemented

• ✅ select_related for user and content_type
• ✅ Indexed fields (moderation_status, photo_type, content_type)
• ✅ CDN delivery for images (not served through Django)
• ✅ Efficient queryset filtering

Recommended Database Indexes

Already in Photo model:

indexes = [
    models.Index(fields=['moderation_status']),
    models.Index(fields=['photo_type']),
    models.Index(fields=['is_approved']),
    models.Index(fields=['created_at']),
]
