I'm no Django expert, but here's what I do.
Use 'exclude' to exclude stuff:
class Message Form(djangoforms.ModelForm):
class Meta:
model = Message
exclude = ['by', 'chat']
Then under the post method of the class that receives the submitted
data add:
data = RealgroupForm(data=self.request.POST)
if data.is_valid():
entity = data.save(commit=False)
entity.by = users.get_current_user()
entity.chat = .. you get the idea
entity.put()
self.redirect('/message?message="sent")
else:
self.redirect...data invalid
