This commit centralizes several core serializer components into the `core` app to promote reusability and improve code organization across the project.
Key changes:
- **Moved Serializers to Core:** `BasePromoSerializer`, `TargetSerializer`, and `CountryField` have been moved from the `business` app to `core.serializers`. This allows them to be reused by other apps, such as `user`.
- **Simplified User Serializers:** The `UserFeedQuerySerializer` now inherits from the `BaseLimitOffsetPaginationSerializer`, and the `OtherFieldSerializer` now uses the
centralized `core.serializers.CountryField`, reducing code duplication and simplifying validation.
This commit refactors the `business` app's views and serializers to improve efficiency and clarify the logic for handling promo data. Key changes: - **Simplified Query Validation:** The `CompanyPromoListCreateView` now validates query parameters directly within the `get_queryset` method, removing the need for an intermediate `list` method override and instance variables. - **Optimized Target Updates:** The `PromoDetailSerializer` now correctly handles updates to the `target` field by calling the parent `update` method first and then saving the `target` field specifically. This ensures atomicity and prevents unnecessary model saves. - **Improved QuerySet Definition:** The `PromoManager` now defines `with_related_fields` as a tuple to clearly specify the fields for `only()`, making the query more readable and maintainable.
Refactor user, promo, and comment serializers to improve maintainability and reduce redundant code by using base classes. - Introduce `BaseUserSerializer` to share common user fields and logic between `SignUpSerializer` and `UserProfileSerializer`. - Create `BaseUserPromoSerializer` to consolidate common fields and methods for `PromoFeedSerializer` and `UserPromoDetailSerializer`. - Implement `BaseCommentSerializer` to streamline `CommentSerializer`, `CommentCreateSerializer`, and `CommentUpdateSerializer`. - Simplify the update logic in `UserProfileSerializer` and extract cache invalidation into a private `_invalidate_cache` method.
Relocate base serializers for users, promos, and comments from the `user` and `business` apps to the central `core` app. This change promotes code reuse and establishes a more logical and scalable project structure. - Moved `BaseUserSerializer`, `BaseUserPromoSerializer`, and `BaseCommentSerializer` to `core/serializers.py`. - Renamed `BasePromoSerializer` to `BaseCompanyPromoSerializer` for clarity. - Updated all dependent serializers in the `user` and `business` apps to inherit from the new centralized base classes in `core`.
