Fix missing callback action error

[JoshAntBrown]

Using the library with Rails 7.1 currently results in this error:

The unlock action could not be found for the :check_for_lockup callback on SomeController, but it is listed in the controller's :except option.

Raising for missing callback actions is a new default in Rails 7.1, if you'd like to turn this off you can delete the option from the environment configurations or set config.action_controller.raise_on_missing_callback_actions to false.

This is because the unlock action does not exist in my applications controllers, nor should I add the unlock action to those controllers.

The LockupController responsible for unlocking already has a skip_before_action/filter call and means the exception was unnecessary. https://github.com/interdiscipline/lockup/blob/86d9955b7600dafd89ad2d47a012ebd95ede8af1/app/controllers/lockup/lockup_controller.rb#L5-L9

I've solved this in my project by adding the following directly to my application controller:

  if respond_to?(:before_action)
    before_action :check_for_lockup
  else
    before_filter :check_for_lockup
  end
