When you access Comment.query, you are getting back an already instantiated
Query object which, as the error message indicates, isn't callable.
I guess I don't really understand why you want to use
Comment.query(Comment.comment) rather than Session.query(Comment.comment). If
you really want this, you could subclass Query to add a __call__ method that
creates a new query instance:
class CallableQuery(Query):
def __call__(self, *args, **kwargs):
return Session.query(*args, **kwargs)
class Comments(Base):
query = Session.query_property(query_cls=CallableQuery)
...but I'm still not sure what the point is.
