Question

I have embed a controller in a template:

{% render "AcmeUserBundle:User:showUsersList"} %}

<a onClick="changeStatus({{user.getUserId()}})"

The aim is simple:

• The user clicks on the link which updates the status via ajax (this works fine)
• Reload the embedded controller only, not the entire page!

At the moment, I managed to do this, by reloading the entire page using document.location.reload(true); This has no point so far…

Here is the ajax part:

//...
function changeStatus(userId){
    $.ajax({
        type: "POST",
        url: ajaxControllerPath,
        data: "userId="+userId,
        success: function(){
            document.location.reload(true); 
        }
    });  
}

How would you reload the embedded controller only?

Answer 1

When you call the ajax controller, this controller could render the showUsersList template and return the generated html as a json object:

$answer['html'] = $this->forward('AcmeUserBundle:User:showUsersList')->getContent(); 
$response = new Response();                                                
$response->headers->set('Content-type', 'application/json; charset=utf-8');
$response->setContent(json_encode($answer));
return $response

Then in your javascript use this generated html to replace the content of the controller part of the page (use a div or similar to identify it)

<div id="changethis">{% render "AcmeUserBundle:User:showUsersList"} %}</div>

function changeStatus(userId){
    $.ajax({
        type: "POST",
        url: ajaxControllerPath,
        data: "userId="+userId,
        success: function(returnData){
            $('#changethis').html(returnData['html']);
        }
    });  
}
