title: Rails "action" params key conflict
body: <p>I am building a RESTful Rails service with various CRUD endpoints. On one of the Create endpoints, the data I am passing in includes:</p>
  
  <pre><code>...
  action: "action_name"
  ...
  </code></pre>
  
  <p>The problem I am having is that <code>params[:action]</code> contains "create", not the actual value of the <code>action</code> parameter I'm passing in. This, I assume, is because <code>params[:action]</code> is being populated by Rails automatically.</p>
  
  <p>Is there another way to access this key I am passing in? Am I doing something blatantly stupid?</p>
