Django: Model Form "object has no attribute 'cleaned_data'"

Solution 1:

For some reason, you're re-instantiating the form after you check is_valid(). Forms only get a cleaned_data attribute when is_valid() has been called, and you haven't called it on this new, second instance.

Just get rid of the second form = SearchForm(request.POST) and all should be well.

Solution 2:

I would write the code like this:

def search_book(request):
    form = SearchForm(request.POST or None)
    if request.method == "POST" and form.is_valid():
        stitle = form.cleaned_data['title']
        sauthor = form.cleaned_data['author']
        scategory = form.cleaned_data['category']
        return HttpResponseRedirect('/thanks/')
    return render_to_response("books/create.html", {
        "form": form,
    }, context_instance=RequestContext(request))

Pretty much like the documentation.

Solution 3:

At times, if we forget the

return self.cleaned_data 

in the clean function of django forms, we will not have any data though the form.is_valid() will return True.
