Hi,
normally in views.py I have a function that takes a request and
returns a render_to_response or the like. I, however, would like it to
take a request and have Django reply with multiple responses. Is there
a way to do this, or is this not possible with HTTP anyway?
What I am trying to achieve: Have a a view that gets called and in it
I have a JS/AJAX script that asks for some data. However, calculating
the data takes a while and it comes one after the other. So I thought
that I could send the data as soon as it becomes available.
In my example I have a graph (using flot) and it would also look
natural to have the data points show up one by one.
A different approach: Have JS ask for more data (using GET) until the
view responses sets a flag (NO_MORE_DATA = True). I don't like this,
since for me this looks like it defies the A in AJAX and the view
would lose all parameters (I.e. which points it already sent and which
not). However, I don't know much JS, nor AJAX nor do I understand the
HTTP protocol good enough.
Maybe this has been done before? Is there a way of having server-side
generated AJAX-actions? Is there a way of having Django send something
within a views-function (as opposed to returning it at the end)?
Some possible code:
def my_view(request):
data =
MyModel.objects.filter('something').order_by('somethingelse')
for item in list(data): # Note, I don't do this but this is just
to show how what I want
send_json(do_something(item)) # send_json() is the crucial
(non-existing) function that I am looking for
return None # or maybe return Done or something like it
Best regards,
Christoph
