Django and Django REST Framework (DRF) patterns: ORM queries, model managers, class-based views, serializers, migrations, and pytest-django testing.

  • Maintaining Django backend applications
  • Calls ruff and mypy
  • Tasks that involve Backend development

What it does

Django Idioms is an agent skill from irahardianto/awesome-agv. Django and Django REST Framework (DRF) patterns: ORM queries, model managers, class-based views, serializers, migrations, and pytest-django testing. Use when building or maintaining Django backend applications. Pair with python-idioms.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Backend development, ORMs and data access and Unit testing. It works with Django, Python, pytest and Ruff. The repository describes itself as: Comprehensive sets of standards and practices designed to elevate the capabilities of AI coding agents. The licence is MIT.

When your agent uses it

  • Maintaining Django backend applications
  • Tasks that involve Backend development
  • Tasks that involve ORMs and data access

Example prompts

  • “/django-idioms”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Fat models, thin views — business logic in models/managers, not views.
  2. Custom managers for common queries
  3. Meta class for ordering, constraints, indexes.

What it can do on your machine

Read from SKILL.md and the folder at commit 9e997ba. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • ruff
    • mypy

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Django Idioms loads about 786 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~786

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Django Idioms and Patterns

Django rewards convention, the ORM, and "batteries included" design. Idiomatic Django = DRY, model-centric, well-tested.

Scope: Django-specific patterns. For Python: @.agents/skills/python-idioms/SKILL.md.

Models

  1. Fat models, thin views — business logic in models/managers, not views.

  2. Custom managers for common queries:

    python
    class TaskManager(models.Manager):
    def active(self):
        return self.filter(status='active')

class Task(models.Model):
    objects = TaskManager()

  3. Meta class for ordering, constraints, indexes.

Views

  1. Class-based views for CRUD, function-based for simple/custom:

    python
    class TaskListView(LoginRequiredMixin, ListView):
    model = Task
    queryset = Task.objects.active()
    paginate_by = 25

  2. DRF serializers for API boundaries:

    python
    class TaskSerializer(serializers.ModelSerializer):
    class Meta:
        model = Task
        fields = ['id', 'title', 'priority', 'created_at']
        read_only_fields = ['id', 'created_at']
ORM
  1. select_related/prefetch_related to avoid N+1 queries.
  2. F() and Q() expressions for complex queries.
  3. Never raw SQL unless ORM can't express it (and then use parameterized queries).
Migrations
  1. One migration per logical change. Squash when history grows.
  2. Data migrations in separate migration files from schema changes.
  3. RunPython with reverse_code for reversibility.
Testing

For universal testing principles, see .agents/rules/testing-strategy.md. Below: language-specific patterns only.

  1. pytest-django over unittest.TestCase:

    python
    @pytest.mark.django_db
def test_create_task():
    task = Task.objects.create(title='Test', priority='high')
    assert task.title == 'Test'

  2. Factory Boy for test data (not fixtures).
