Answer 1

You are not returning a response if form is not valid:

You can move return render_to_response one indentation block to the left

def addaNonProfit(request):
    """we need NonProfits.""" 
    if request.method == 'POST':
        form = NonProfitForm(request.POST)
        if form.is_valid():
            new_nonProfit = form.save(request.user)
            return HttpResponseRedirect(reverse(new_nonProfit, args=(new_nonProfit.slug,)))
    else:
        form = NonProfitForm()
    return render_to_response('addaNonProfit.html',{'form': form},context_instance=RequestContext(request))

Answer 2

If the method is POST and the form is invalid, you don't return anything. You have to return an HttpResponse from every path in your view.
