The following code creates a form based on a model, Post. Problem I am facing is that the form never validates and gives ValueError that data did not validate if I remove the if post_form.is_valid(): check.
However, if I keep the code as shown below, that is, I keep the if post_form.is_valid(): check, then it always fails and the else block is executed.
I was trying to save the User, which is a ForeignKey to Django's Auth, in my model and it turns out I cannot even get past this vlaidation error.
Any help will be appreciated. Thanks.

return self.name

In your other post, you were trying to automatically insert the user field, which probably means you don't have a user field displayed in the template.
Exclude it if you plan to insert the user anyways.
class PostForm(ModelForm):
class Meta:
model = Post
exclude = ('user',) # exclude this
if request.method == 'POST':
post_form = PostForm(request.POST)
if post_form.is_valid():
post = post.save(commit=False)
post.user = request.user
post.save() # now post has a user, and can actually be saved.
return render_to_response('home.html')
