finish_upload_status(options = {}) public

This method must be called by the action that receives the form post with the upload_progress. By default this method is rendered when the controller declares that the action is the receiver of a form_tag_with_upload_progress posting.

This template will do a javascript redirect to the URL specified in redirect_to if this method is called anywhere in the controller action. When the action performs a redirect, the finish handler will not be called.

If there are errors in the action then you should set the controller instance variable +@errors+. The +@errors+ object will be converted to a javascript array from +@errors.full_messages+ and passed to the finish handler of form_tag_with_upload_progress

If no errors have occured, the parameter to the finish handler will be undefined.

Example (in view)

 <script>
  function do_finish(errors) {
    if (errors) {
      alert(errors);
    }
  }
 </script>

 <%= form_tag_with_upload_progress {:action => 'create'}, {finish => 'do_finish(arguments[0])'} %>
