Narrow this down and you should be able to work through it.
First - is the view getting invoking correctly, regardless of what
newforms is doing? If you're running on a dev server instance (i.e.
django-admin runserver), then try printing out the request.POST or
request.GET in the view to see what is coming through.
You can also invoke django-admin shell and load up the Form and "poke
at it", which I've found to be a pretty good debugging tool. i.e.
>>> import forms
>>>
>>> example_data = { 'name' : 'test', 'description' : 'blue', 'vendor'
: 'ford' }
>>> f = forms.AddTypeForm(example_data)
>>> f.is_valid()
True
or whatever.
Break it down into steps to debug it, and then determine if each piece
is working. You'll make good progress that way.
