Hmmmm it seems to have just dropped my supplementary question. Apologies if this arrives twice.
I want to do something like: /myapp/api/get_comment/id to return the comment at id and /myapp/api/get_comment/ to return a list of all comments However, it complains when I try this (invalid argument). I try to test id against None, but it's a server object so isn't None. Is this doable or do I give up and define get_all_comments?
