Add Field

Add a field to a Django model and propagate it to admin, serializer, and factory.

Usage

jig run ${CLAUDE_SKILL_DIR}/recipe.yaml --vars '{"model_name": "<Model>", "field_name": "<name>", "field_type": "<Type>", "field_args": "<args>", "factory_default": "<default>"}'

Variables

• model_name: Model class name (e.g. Reservation)
• field_name: New field name (e.g. loyalty_tier)
• field_type: Django field type (e.g. CharField)
• field_args: Field arguments (e.g. max_length=20, default="bronze")
• factory_default: Factory default value (e.g. "bronze")

Extract these from the user's request.

Gotchas

• If jig exits non-zero, it prints the rendered templates to stderr. Use that output to apply changes manually.
• The recipe uses anchor-based patching. If the anchor pattern doesn't match the actual class definition, jig will fail. Fall back to manual editing using the stderr output.
