[symfony-users] What's the best way to suppress redirects in the admin generator for ajax actions?

[ashton]

Hi!
I have a "wizard" in my admin generator that ajax posts to multiple
different modules to step the user through creating objects in the
correct order.

I'm using the generated actions, so I post to (in one example)
"facility/create" and the object is created.  Works like a charm,
except that there is no feedback.
I'm having some trouble determining how to build the response.  The
generated executeCreate action calls processForm, and processForm is
hardcoded to redirect to facility/edit if the insertion is
successful.  This is not the behavior that I want when I'm using
ajax.  I just want a little JSON back.

I could override processForm(), or redirect() in all the actions, but
that seems like too much redundant code (I'm creating objects like
this in several modules).  It seems as if there should be some good
way to suppress or block the redirect.

Is there a good way to keep processForm from redirecting to the edit
page?
and/or
Is there a better way to accomplish the ajax creates?

thanks!

class facilityActions extends autoFacilityActions
{
    //I can't do this because processForm redirects.
    public function executeCreate(sfWebRequest $request) {
        parent::executeCreate($request);
        if($isAjax = $this->getRequest()->isXmlHttpRequest()) {
            return $this->renderText(json_encode(array
('status'=>'error')));
        }
    }
}

class autoFacilityActions extends sfAction
{
  protected function processForm(sfWebRequest $request, sfForm $form)
  {
    $form->bind($request->getParameter($form->getName()), $request-
>getFiles($form->getName()));
    if ($form->isValid())
    {
      $notice = $form->getObject()->isNew() ? 'The item was created
successfully.' : 'The item was updated successfully.';

      $facility = $form->save();

      $this->dispatcher->notify(new sfEvent($this,
'admin.save_object', array('object' => $facility)));

      if ($request->hasParameter('_save_and_add'))
      {
        $this->getUser()->setFlash('notice', $notice.' You can add
another one below.');

        $this->redirect('@facility_new');
      }
      else
      {
        $this->getUser()->setFlash('notice', $notice);

        $this->redirect(array('sf_route' => 'facility_edit',
'sf_subject' => $facility));
      }
    }
    else
    {
      $this->getUser()->setFlash('error', 'The item has not been saved
due to some errors.', false);
    }
  }
