Thankyou for the reply.

Yeah I am aware of the get vs post. The class I posted was just to actually print all the Groups().

The issue I have is I'm unsure how I use the models to keep data in a sort of hierarchical fashion, with Groups > Topics > Pros/Cons.

Grabbing data is simple enough and I am using:

class NewGroupSubmit(webapp.RequestHandler):
    def post(self):

        group = Groups()
        if users.get_current_user():
            group.group_user = users.get_current_user()     
        group.group_name = self.request.get('groupname')

        group.put()
        self.redirect('/summary')

I need another function to add a new topic, that stores it within that group. So lets say a group is "Cars" for instance; the topics might be "Ferrari", "Porsche", "BMW", and then pros/cons for each topic. I realise I'm being a little vague, but it's because I'm very new to relational databasing and not quite used to the terminology.
