Hi,

I don't understand the purpose of the __iter__ method of the  MyRoot class
in the alchemy scaffold:

 def __iter__(self):
        session= DBSession()
        query = session.query(MyModel)
        return iter(query)

When is it called by pyramid ? Should that be overriden ? Should that be
defined in childs resources ?
I can't see any doc on the subject.

Thanks
