Overrides

This guide is an introduction to how overriding Rhino behaviour works.

Overrides​

Rhino implements the pattern defined in https://nubinary.github.io/rhino-guides/engines.html#improving-engine-functionality both in its engines and in config/application.rb for the Boilerplate.

You may override classes in Rhino this way or may override classes that Rhino itself overrides.

It is recommended you follow the pattern app/overrides/<gem_or_engine>/<class>_override.rb

You can use class_eval as noted in the above guide, or if you need to call super of the method you are overriding use the Mixin Prepending pattern defined in https://stackoverflow.com/questions/4470108/when-monkey-patching-an-instance-method-can-you-call-the-overridden-method-from/4471202. See registrations_controller_override.rb for an example.

What Rhino Overrides​

Rhino itself overrides some classes of dependent gems.

DeviseTokenAuth::ConfirmationsController​

Overrides show in order to redirect to the front end if an error is thrown

DeviseTokenAuth::OmniauthCallbacksController​

Overrides omniauth_success in order to set the auth cookie before redirect so client is logged in.

DeviseTokenAuth::PasswordsController​

Overrides render_edit_error in order to redirect to the front end if password reset token has expired

DeviseTokenAuth::SessionsController​

Overrides render_destroy_error in order to clean the auth cookie if there's any error during sign out.

DeviseTokenAuth::TokenValidationsController​

Overrides render_validate_token_error in order to clean the auth cookie if there's any error in validating the current token.

ActiveStorage::DirectUploadsController​

Overrides create in order to enforce authorization

What Rhino Organizations Overrides​

DeviseTokenAuth::RegistrationsController​

Overrides create in order to create a new organization on registration

DeviseTokenAuth::OmniauthCallbacksController​

Overrides omniauth_success in order to create a new organization on registration

Testing Overrides​

Rhino provides Rhino::TestCase::Override for testing policies.
