Django

Follow a Django operation from its URL and view through input validation, business logic, and response construction. Make the intended contract explicit at each boundary. A consumer should be able to rely on the API's documented fields without depending on incidental details of the database model.

Start with the Django API request guide to separate framework facilities from application decisions. Define who can act on the specific object, which fields can be supplied, and what a denied or invalid request should return. Keep these requirements close to the implementation.

The Django QA article develops a repeatable verification plan. Check actual data effects alongside response shape, and use controlled identities for permission cases. Add a focused deployment check when the important behavior depends on a boundary that an in-process test does not exercise.
