What you will learn

  • ORM relations, validated writes, sessions, permissions, pagination, and tests.

  1. ORM queries and relationship loading

    Build bounded queries, understand lazy evaluation, and choose related-object loading from the actual response contract.

    Start learning

  2. ModelForms and domain validation

    Use declared writable fields and explicit cleaning while keeping server-owned identity and concurrent constraints outside client control.

    Start learning

  3. Authentication and session lifecycle

    Use the configured authentication system and session workflow without confusing a signed-in identity with permission for every resource.

    Start learning

  4. Permissions and object scope

    Apply model permissions and resource-level access rules at the trusted view boundary before reading or changing protected data.

    Start learning

  5. Generic views and bounded pagination

    Use class-based view contracts deliberately and paginate a scoped, deterministically ordered dataset without loading everything first.

    Start learning

  6. Testing requests and application boundaries

    Match unit, client, database, and browser evidence to the promise being tested, with explicitly isolated settings and fixtures.
