local variable 'form' referenced before assignment

My View :

def refer(request, seek_id):
    seek_obj = SeekSolutions.objects.get(pk = seek_id)
    if request.method == 'POST':
        form = SeekReferForm(request.POST)
        if form.is_valid():
            obj = form.save(commit = False)
            obj.refferer = request.user
            obj.seek_id = seek_obj
            obj.save()
            send_message(obj)
            return HttpResponseRedirect('/seek/referred')
    return render_to_response('seek/refer.html', {'form' : form , } )

Although this question is pretty old, since I ran in to the same problem(and just solved it) I think I ought to answer to it for future references. But then I had a different error. But you seem to be missing something in your code.

def refer(request, seek_id):
seek_obj = SeekSolutions.objects.get(pk = seek_id)
if request.method == 'POST':
    form = SeekReferForm(request.POST)
    if form.is_valid():
        obj = form.save(commit = False)
        obj.refferer = request.user
        obj.seek_id = seek_obj
        obj.save()
        send_message(obj)
        return HttpResponseRedirect('/seek/referred')
else:
    form = SeekReferForm()
return render_to_response('seek/refer.html', {'form' : form , } )

This includes an else block to your first if. This is because when you try to access the url from your browser, you are essentially doing a GET request on the resource. As a result the first if is violated and comes directly to the return statement where it tries to return a dictionary item with 'form' as the key and a form object which was never created at all. Thus the error in your code. There need to be an else part which is supposed to instantiate the form object in case you try to open the url in your browser. I hope that helps the cause.

the form is instantiated only when request.method == 'POST'.
