Thanks for helping a newbie!

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

Hi folks,
I'm trying to write a basic chat application.
my models currently look like
***
# models.py
from google.appengine.ext import db
class Chat(db.Model):
name = db.StringProperty
class User(db.Model):
name = db.StringProperty()
ip = db.StringProperty()
class Message(db.Model):
chat = db.ReferenceProperty(Chat, required=True,
collection_name='chat')
by = db.ReferenceProperty(User, required=True,
collection_name='by')
date = db.DateTimeProperty(auto_now_add=True)
message = db.StringProperty(multiline=True)
from google.appengine.ext.db import djangoforms
#from django import newforms as forms
class MessageForm(djangoforms.ModelForm):
class Meta:
model = Message
***
What I want is to have the message itself submitted via the form,
but to populate the 'by' and 'chat' parameters.
I figure the form will submit some sort of chatId and userId. I'll
need to map those across to User and Chat models. Add them to the
Message model, and then I'm ready to save.
How should I go about this?
Cheers,
Peter

No problem.
