Thanks a lot. Your solution was the right one. However, I just needed to provide 'pid' as the only argument for the pop method.
Now when I use the following command in my view it doesn't give me any error: form = VoteRadioForm(request.POST, pid = 2 ) However, I'm having a problem with form validation since is_valid returns false. I think my form is not created correctly. Because when I issue cleaned_data method, I get the following error: 'VoteRadioForm' object has no attribute 'cleaned_data' I need to sleep now. Hopefully, tomorrow I am able to figure out this problem.
