Django - save data on submit but not reload view

I have a view that display a form that can be saved with a submit button. I dont want the view to be reloaded when the form is submit. However, I have an error if the function do not return a response.

view.py

from django.shortcuts import render_to_response
from ezmapping.models import *
from django.forms.models import modelformset_factory

def setAppOptions(request, map_name):
    if request.user.is_authenticated():
        app_selected = EzApp.objects.get(app_name=app_name, created_by=request.user)
        formset = ezAppOptionFormSet(user=request.user, instance=app_selected)
        if request.method == 'POST':
            formset = ezAppOptionFormSet(request.POST, instance=app_selected, user=request.user)
            if formset.is_valid():
                formset.save()

        return render_to_response("manage_app_options.html", {'formset': formset}, context_instance=RequestContext(request)) 
    else:
        error_msg = u"You are not logged in"
        return HttpResponseServerError(error_msg)

You won't be able to do the POST without re-rendering the template, unless you're posting the form via ajax. If you submit the form via ajax and get a response back that is JSON, XML, etc, you can then update the template with the form errors or other information.

However, given the use case outlined in your view, I would suggest limiting access to the view altogether using the @login_required decorator. If you do that, your view logic can be greatly simplified.
