title: How do I override the PasswordsController actions in a rails app with ActiveAdmin & Devise
body: <p>I have a rails app that is setup to use ActiveAdmin and Devise.</p>
  
  <p>I want to override the <em>edit</em> and <em>update</em> actions in the PasswordsController.
  As far as I can tell, ActiveAdmin is relying on Devise's PasswordsController.</p>
  
  <p>Do I need to use ActiveAdmin's method for customizing a controller / resource to do this? If so what resource is in play to "register" for the PasswordsController?</p>
  
  <p>Or do I need to copy Devise's entire PasswordsController from the gem to somewhere in my app and change the actions I want to change? If so what folder would I put my copy of the Devise controller so it overrides the gem's version?</p>
  
  <p>What is the correct way to do this?</p>
