This Skill solves the common Django pain point of tangled, hard-to-test code where business logic is mixed into views, model methods, or scattered across the codebase, making changes risky and tests slow and dependent on the database.
Use the dj-services skill to refactor the order creation logic from your Django view into a dedicated OrderService class with injected repository dependencies, registered in the project's svcs registry.

To separate Django business logic from ORM concerns, extract logic into plain Python service classes that delegate all database access to repositories and communicate across boundaries using typed Pydantic DTOs. This ensures services never import Django models directly.
Refactor a fat Django view into a testable service layer by moving order creation, inventory checks, and payment processing into a dedicated stateless service class with constructor-injected repository dependencies, then register it in a centralized DI registry.
Write database-free unit tests for Django business logic by using constructor-injected dependencies in stateless service classes so you can inject mock repositories directly, eliminating slow database queries and isolating pure business rules.
The svcs dependency injection registry is used to wire Django services and repositories once at startup so they can be resolved anywhere across views, Celery tasks, management commands, and tests without tight coupling or direct ORM imports.
Use the repository pattern and service layer in Django when business logic is tangled across views and model methods, making changes risky and tests slow. This architecture enforces strict separation of concerns and enables fast, isolated testing.
Yes, you can resolve registered Django services inside Celery tasks and management commands. The centralized svcs registry configures dependency injection at startup, allowing services to be consistently resolved across views, background tasks, and commands.
