title: Rails 4 before_action, pass parameters to invoked method
body: <p>I have the following code:</p>
  
  <pre><code>class SupportsController &lt; ApplicationController
    before_action :set_support, only: [:show, :edit, :update, :destroy]
    ....
  </code></pre>
  
  <p>Is it possible to pass a string to the method <code>set_support</code> to be applied for all 4 view methods?
  Is it possible to pass a different string to the method <code>set_support</code> for each method in the view?</p>
