title: send parameters from drop_receiving_element
body: <p>users can be dragged to nodes to move or copy a user from one node to another node. I have a problem with how I send the variables to user move and copy methods in userscontrol. </p>
  
  <p>The drop zone is defined as:</p>
  
  <pre><code>&lt;%=drop_receiving_element "move_drop_zone_"+node.id.to_s, 
    :update =&gt; "users", 
    :url =&gt; move_user_path(:id =&gt; node.id),
    :method =&gt; :put,
    :accept =&gt; "move_user" %&gt;
  </code></pre>
  
  <p>The draggable user in a node is defined as:</p>
  
  <pre><code>&lt;span id="move_user_&lt;%=user.id%&gt;_&lt;%= node.id.to_s %&gt;" class="move_user" &gt;
    &lt;%=image_tag('move_user.png') %&gt;
  &lt;/span&gt; 
  &lt;%= draggable_element "move_user_" + user_node, :revert =&gt; true %&gt;
  </code></pre>
  
  <p>I also added to routes:</p>
  
  <pre><code>map.resources :users, :member =&gt; { :move =&gt; :put, :copy =&gt; :put }
  </code></pre>
  
  <p>The problem is that I don't know how to pass the user id and from node id. Since it's a put operation I only see the id (which is the target node id) defined in the url of drop_receiving_element. </p>
  
  <p>Thanks,
  Stijn</p>
