Symfony2 - 正确地做事

having a bit of trouble working out the best way to do things. I have a normal form, this form already has an action and a data-url

<form action="{{ path('NickAlertBundle_create') }}" data-url="{{ path('NickAlertBundle_view') }}" method="post" enctype="multipart/form-data">

When the form is submitted, it goes to a javascript file and ajax takes care of it

$.ajax({
    type: "POST",
    url: $("#addAlertForm").attr("action"),
    data: data,
    success: function(data) {
        if(data){
            var splitdata = data.split(":");
            if(splitdata[0]=="Success"){
                var id = splitdata[1];
                alert("Your alert has been added");
                document.location.href= $("#addAlertForm").attr('data-url');
            }else{
                alert(data);
            }
        }else{
            alert("Unknown Error!");
        }
    },
    error:function(){
        alert("Error! Please try again");
    }
});

So it essentially post some data to my forms action route. If it comes back with the message Success, it redirects the user to my data-url route.

So this all works fine. In my createAction I insert the data to the database and if this is successful I return Success. The user is then redirect to the view-alerts (viewAction) page to see the data.

public function createAction(Request $request)
{
    try {
        //Get data

        $em = $this->getDoctrine()->getManager();

        $alert = new AvailabilityAlert();
        $alert->setSearchCommand($na_command);
        $alert->setLastUpdated();
        $em->persist($alert);

        $em->flush();

        return new JsonResponse('Success');

    }catch (Exception $e) {
    }

}

public function viewAction()
{
    $repository = $this
    ->getDoctrine()
    ->getManager()
    ->getRepository('NickAlertBundle:AvailabilityAlert');

    $alerts = $repository->getAllActiveAlerts();

    return $this->render('NickAlertBundle:Page:view.html.twig', array(
        'alerts' => $alerts,
    ));
}

So this all works great, but now a problem. If the createAction is successful, I now need to do a load of other stuff which involves passing the alert to a new class so I can do some web services stuff with it (nothing is displayed to the user, everything is done in the background).

To do the above, I essentially new to add something like the following to the end of my create action

include 'cron_single.php';
addFlightsAction($alert);

Doing this seems wrong though. So I was thinking about creating a separate action for this, I think this would be the correct way to do this. So in the ajax above, if the response is Success (where I do the redirect), I could potentially call another route. To do this though, I would have to give my form something like another data-url so I can get the route, and having so many of these in my form seems incorrect.

Another thing I am thinking of is doing something directly at the end of the createAction, such as call a route. Don't know if this is possible?

What would be the best way to handle something like this?

Thanks
