Severity: error

Summary: has_many or has_one relation is missing required foreign_key field

What this means

A has_many or has_one relation has no foreign_key: attribute. The foreign_key names the column on the related resource’s table that references this resource’s primary key. Without it, Shaperail cannot generate the correct SQL join.

Example that triggers this

relations:
  orders: { resource: orders, type: has_many }

How to fix it

Add foreign_key: <column_on_related_table> to the relation:

orders: { resource: orders, type: has_many, foreign_key: user_id }
