Instance Method Details

#after_initialize_with_autoload ⇒ Object

Searches for models that use has_many_polymorphs or acts_as_double_polymorphic_join and makes sure that they get loaded during app initialization. This ensures that helper methods are injected into the target classes.

Overrides Rails::Initializer#after_initialize.
