Rails Patterns

Follow these patterns when working in Rails applications.

Strict Loading for N+1 Prevention

• New models should include self.strict_loading_by_default = true.
• Resolve violations with .includes(:association) or .preload(:association).
• Use :n_plus_one_only mode in development for practical DX.
• Configure :log mode in production to prevent crashes.
• Bypass in FactoryBot with record.strict_loading!(false) in after(:build) hooks.
