Re: Please wait page trouble

Could you post the full url.py file?

And as Brian mentioned your javascript block should be separated. Plus you have an extra }); that's going to fail once you resolve this reverse error. It's also not clear what you intend to happen when run_DHM returns its response? It looks like your intent is to do a redirect and run_DHM will use session data to retrieve calculation results.

Just to clarify, I think your plan is to:

1. Display a Please Wait page that fires off an AJAX call to some view that performs calculations => run_DHM. The results of the calculations are stored in the session.
2. run_DHM returns a simple response that will indicate sucess, e.g., "OK"
3. Redirect to a view to display the results, which are retrieved from the session => display_DHM

I think you need three views here: please_wait, run_DHM, and display_DHM.

def run_DHM(request):
//put calculated data in request.session
   return render_to_response('DHM_ran.html', request.session,
context_instance=RequestContext(request))

This is the django error

Caught NoReverseMatch while rendering: Reverse for 'run_DHM' with
arguments '()' and keyword arguments '{}' not found.

run_DHM takes 'request' as an argument. How do I pass it the argument??
