title: How can I add common actions to controllers without using inheritance?
body: <p>I need to add common actions to a number of my controllers without using inheritance. All our controllers extend an Abstract controller and the functionality I want to include does not make sense in the abstract controller.</p>
  
  <p>My initial idea was to use a Mixin, but it appears that actions, since they are closures, are not 'mixed-in' to the controllers that include the mixin, only methods are.</p>
  
  <p>Can anyone suggest a way I can get "mixin' like functionality to add actions to controllers?</p>
  
  <p>thanks!</p>
