Skill: Implement Django Feature

1. Domain Modeling (The Foundation)

Always start here.

• Create/Update models.py.
• Enforce id = models.UUIDField(default=uuid.uuid4, editable=False, primary_key=True).
• Add created_at and updated_at (TimeStamped).
• Define __str__ method.

2. Business Logic Layer

Do not put heavy logic in Views.

• Create a services.py or selectors.py in the app.
• selectors.py: For fetching data (QuerySets, filtering).
• services.py: For writing data (Transactions, complex creates).
