Add Field

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

Inputs

Prefer structured arguments from $ARGUMENTS when available.

Accepted forms:

1. JSON object with keys:
   • model_name
   • field_name
   • field_type
   • field_args
   • factory_default
2. Positional args:
   • <model_name> <field_name> <field_type> [field_args] [factory_default]

Normalization rules:

• field_args should be raw Django field args without wrapping parentheses. Example: max_length=20, default="bronze"
• factory_default should be a Python literal rendered into the factory line. For string defaults, include quotes in the value (example: "bronze").
• If optional args are omitted, use:
  • field_args: ""
  • factory_default: "'test'"

Usage

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

If invoked as /add-field <model_name> <field_name> <field_type>:

jig run ${CLAUDE_SKILL_DIR}/recipe.yaml --vars '{"model_name": "$1", "field_name": "$2", "field_type": "$3", "field_args": "", "factory_default": "\"test\""}'

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 unsure about required variables, run:
  • jig vars ${CLAUDE_SKILL_DIR}/recipe.yaml
• If jig exits non-zero, it prints rendered output to stderr. Use that output for one manual correction pass.
