Defined in:

Overview

This cop disallows adding global models to the ‘app/models` directory.

The goal is to encourage developers to put new models inside the correct namespace, where they can be more modularly isolated and ownership is clear.

Examples:

# bad
# path: components/my_component/app/models/foo.rb
class Foo < ApplicationRecord
  # ...
end

# good
# path: components/my_component/app/models/my_component/foo.rb
module MyComponent
  class Foo < MyComponent::ApplicationRecord
    # ...
  end
end
