description	Add a new field to a Django model and propagate to admin, serializer, and factory. Use when adding model fields or database columns.

Add Field

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

Template-First Mode

This variant is template-first. Start by using template files as the source of truth:

• templates/model_field.j2
• templates/admin_field.j2
• templates/serializer_field.j2
• templates/factory_field.j2
• templates/vars.tmpl.json

Map the user request into the vars shape, then apply the corresponding edits directly.

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\")

Rendered Example For This Task

Given:

• model_name=Reservation
• field_name=loyalty_tier
• field_type=CharField
• field_args=max_length=20, default="bronze"
• factory_default="bronze"

Render to these exact line shapes:

• model line: loyalty_tier = models.CharField(max_length=20, default="bronze")
• admin list_display entry: "loyalty_tier",
• serializer fields entry: "loyalty_tier",
• factory line: loyalty_tier = "bronze"

Gotchas

• Keep variable normalization consistent with templates/vars.tmpl.json.
• Keep indentation exactly as shown by each template snippet.
• Add only the required field propagation edits; avoid unrelated refactors.
