SR004

Severity: error

Summary: schema has no primary key field

What this means

The schema has one or more fields, but none of them has primary: true. Shaperail requires exactly one primary key per resource to generate correct SQL, route handlers, and CRUD operations.

Example that triggers this

resource: users
version: 1
schema:
  name: { type: string, required: true }

How to fix it

Add primary: true to one field (typically id):

id: { type: uuid, primary: true, generated: true }
