Add Field

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

Inputs

Prefer bash-style argument mapping when arguments are available.

Accepted forms:

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

Usage (Bash Style)

Map values into shell variables, then run jig run once:

MODEL_NAME="$1"
FIELD_NAME="$2"
FIELD_TYPE="$3"
FIELD_ARGS="${4:-max_length=20, default=\"bronze\"}"
FACTORY_DEFAULT="${5:-\"bronze\"}"

jig run ${CLAUDE_SKILL_DIR}/recipe.yaml --json-args "{\"model_name\":\"${MODEL_NAME}\",\"field_name\":\"${FIELD_NAME}\",\"field_type\":\"${FIELD_TYPE}\",\"field_args\":\"${FIELD_ARGS}\",\"factory_default\":\"${FACTORY_DEFAULT}\"}"

If values come directly from the prompt, assign them first using the same variable names and run the same command.

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\")

Gotchas

• Run exactly one jig run command first.
• If unsure about required variables, run: jig vars ${CLAUDE_SKILL_DIR}/recipe.yaml
• If jig exits non-zero, use stderr rendered output for one manual correction pass.
