I think the usual way to do this is to do a query for the comments in
your movie controller's `view` action:
class MovieController(BaseController):
def view(self, ...):
# stuff
c.comments = Session.query(Comment).all() # or whatever query
makes sense
# more stuff
return render(...)
If you have a complex Comment query that you need often, you might
create a class method in your Comment class, but for a simple query,
I'd just inline it as I did above.
