title: Rails datatables ajax json 414 request URI too large
body: <p>So I've tried the <a href="http://railscasts.com/episodes/340-datatables">Railscasts</a> tutorial, as well as the one for the <a href="http://rubydoc.info/gems/ajax-datatables-rails/0.0.1/frames">ajax-datatables-rails</a> gem. I'm creating a list of clients from a database--not users. I believe I've narrowed it down to the fact that when using the <code>GET</code> method via Datatables' <code>sServerMethod</code>, I receive a 414 with "<strong>Request-URI too large</strong>". When I use the <code>POST</code> method, I simply get null values for all attributes except <code>id</code> which makes sense since the POST json is used for creating a client. Any help is greatly appreciated!</p>
  
  <p>Here is my code and diagnostics response:</p>
  
  <pre><code>// custom.js    
  $("#datatable").dataTable({
          "bJQueryUI": true,
          "sPaginationType": "full_numbers",
          "bProcessing": true,
          "bServerSide": true,
          "sAjaxSource": $('#datatable').data('source'),
      });
  </code></pre>
  
  <p>Response:</p>
  
  <pre><code>http://127.0.0.1:3001/clients.json
  Request-URI Too Large
  </code></pre>
