Re: StreamingHttpResponse into a Template

Yes, you are perfectly right about the fact that this is a bad implementation.
the fact is that where i host the code it does not support celery (so far). so i've to find out a workaround to be able to process a bunch of external APIs Call (that include the one for sending email). 
we'll probably keep the javascript reloading to process junks, waiting for the support of celery.

BTW: the StreamingHttpResposnse, when should it be used? i get the example on the docs about writing a cvs, pdf or similar, but, what else?

Thanks for the help.

Django 1.5 is just came out and it ships the StreamingHttpResponse. 

What i want to do is to print the output of a stream response into a template, having for example a bar that grows based on the streamed data (something similar to a loading bar).

so far i've found a solution that basically is to write the pieces of the final html page into the generator function, so each yield does a render_to_text of a piece of the final html page (i splitted it manually) putting each time the data just processed. 

The problem of this solution is that i can't have the loading bar. What I'm able to have are incremental data, so i can print out the list of processed data, but it's different to what i want to do.

Is there a way to do what i would like to do?
