this will need to be handled likely in View, ViewHandler and ViewResponseListener

for the later this is what SensioFrameworkExtraBundle

        if (!$request->attributes->get('_template_streamable')) {
            $event->setResponse($templating->renderResponse($template, $parameters));
        } else {
            $callback = function () use ($templating, $template, $parameters) {
                return $templating->stream($template, $parameters);

            $event->setResponse(new StreamedResponse($callback));

This feature look nice to me ! Is there any particulars reasons why this feature could not be implement ?


lsmith77 commented Jul 29, 2014

no .. I do not think anyone ever tried to implement it

mcg-web commented Jul 29, 2014

Ok thank you for your answer. I'll try to implement it.

+1 this is crucial ❗️

We have API method for generating report. It can be returned as json or xml with simple array passed from controller. However, we would like to serve csv and xlsx formats, then controller would return StreamedResponse. Now we have to register custom handler (in development now, I hope it will work..). Would be so easier with this feature.

Wasn't it implemented since 2012 or I'm missing something?

I'd like to see this as well, though I think it's most useful in conjunction with a serializer that supports streams as well, and JMS/Serializer does not.
