Updated ImageService to use default_storage.url() instead of manually
constructing URLs. This ensures images displayed on the frontend correctly
include the tenant_id in the path, enabling proper file access within
multi-tenant environment.
Changes:
- ImageService.get_url() now delegates to default_storage.url()
- All image URLs now include /media/tenants/{tenant_id}/ path
- Ensures consistent behavior with TenantAwareFileSystemStorage
- Frontend photos now display correctly with tenant isolation
Result:
- Thumbnail URLs: /media/tenants/papa/products/4/28/thumb.webp
- Medium URLs: /media/tenants/papa/products/4/28/medium.webp
- Large URLs: /media/tenants/papa/products/4/28/large.webp
- Original URLs: /media/tenants/papa/products/4/28/original.jpg

Resolves critical bug where photos of products with the same ID in different
tenants were overwriting each other. Implemented complete isolation of media
files between tenants using custom Django storage backend.
## Changes
### New Files
- products/utils/storage.py: TenantAwareFileSystemStorage backend
* Automatically adds tenant_id to file paths on disk
* Prevents cross-tenant file access with security checks
* Stores clean paths in DB for portability
- products/tests/test_multi_tenant_photos.py: Comprehensive tests
* 5 tests covering isolation, security, and configuration
* All tests passing ✅
- MULTITENANT_PHOTO_FIX.md: Complete documentation
### Modified Files
- settings.py: Configured DEFAULT_FILE_STORAGE to use TenantAwareFileSystemStorage
- products/models/photos.py:
* Converted upload_to from strings to callable functions
* Updated ProductPhoto, ProductKitPhoto, ProductCategoryPhoto
* Added tenant isolation documentation
- products/tasks.py: Added documentation about file structure
- products/utils/image_processor.py: Added documentation
- products/utils/image_service.py: Added documentation
## Architecture
**On disk:** media/tenants/{tenant_id}/products/{entity_id}/{photo_id}/{size}.ext
**In DB:** products/{entity_id}/{photo_id}/{size}.ext
Tenant ID is automatically added/removed during file operations.
## Security
- Storage rejects cross-tenant file access
- Proper tenant context validation
- Integration with django-tenants schema system
## Testing
- All 5 multi-tenant photo tests pass
- Verified photo paths are isolated per tenant
- Verified storage rejects cross-tenant access
- Verified configuration is correct
## Future-proof
- Ready for S3 migration (just change storage backend)
- No breaking changes to existing code
- Clean separation of concerns

Реализована полноценная система мультитенантности на базе django-tenants.
Каждый магазин получает изолированную схему БД и поддомен.
Основные компоненты:
Django-tenants интеграция:
- Модели Client (тенант) и Domain в приложении tenants/
- Разделение на SHARED_APPS и TENANT_APPS
- Public schema для общей админки
- Tenant schemas для изолированных данных магазинов
Система регистрации магазинов:
- Публичная форма регистрации на /register/
- Модель TenantRegistration для заявок со статусами (pending/approved/rejected)
- Валидация schema_name (латиница, 3-63 символа, уникальность)
- Проверка на зарезервированные имена (admin, api, www и т.д.)
- Админ-панель для модерации заявок с кнопками активации/отклонения
Система подписок:
- Модель Subscription с планами (триал 90 дней, месяц, квартал, год)
- Автоматическое создание триальной подписки при активации
- Методы is_expired() и days_left() для проверки статуса
- Цветовая индикация в админке (зеленый/оранжевый/красный)
Приложения:
- tenants/ - управление тенантами, регистрация, подписки
- shops/ - точки магазинов/самовывоза (tenant app)
- Обновлены миграции для всех приложений
Утилиты:
- switch_to_tenant.py - переключение между схемами тенантов
- Обновлены image_processor и image_service
Конфигурация:
- urls_public.py - роуты для public schema (админка + регистрация)
- urls.py - роуты для tenant schemas (магазины)
- requirements.txt - добавлены django-tenants, django-environ, phonenumber-field
Документация:
- DJANGO_TENANTS_SETUP.md - настройка мультитенантности
- TENANT_REGISTRATION_GUIDE.md - руководство по регистрации
- QUICK_START.md - быстрый старт
- START_HERE.md - общая документация
Использование:
1. Пользователь: http://localhost:8000/register/ → заполняет форму
2. Админ: http://localhost:8000/admin/ → активирует заявку
3. Результат: http://{schema_name}.localhost:8000/ - готовый магазин

- Added default_storage import to ImageService
- Implemented fallback logic in get_url() method
- First tries new format (.webp for non-original, .jpg for original)
- Falls back to old format (all .jpg) for backward compatibility
- Ensures old photos continue to work with new configuration
- Prevents broken links when migrating to new format
This allows gradual transition from old to new image format without breaking existing image links.

Refactored image processing system to use centralized configuration in settings.IMAGE_PROCESSING_CONFIG instead of hardcoded values.
Changes:
- Added IMAGE_PROCESSING_CONFIG to settings with configurable sizes, formats, and quality
- Rewrote ImageProcessor to use dynamic configuration from settings
- Added support for multiple image formats (JPEG, WebP, PNG)
- Updated _save_image_version() to handle different formats and quality levels
- Added original image scaling (max 2160×2160) and square aspect ratio
- Updated ImageService to work with different file extensions (.jpg, .webp, .png)
- All parameters now easily configurable without code changes
Configuration:
- Original: JPEG, quality 100, max 2160×2160 (always square)
- Large: WebP, quality 90, 1200×1200
- Medium: WebP, quality 85, 600×600
- Thumbnail: WebP, quality 80, 200×200
Benefits:
- Flexible and maintainable configuration
- Smaller file sizes (WebP for resized images)
- Maximum quality for originals (JPEG 100)
- Square aspect ratio for better consistency
