[SQLObject] Sorting a list of selected SQLObjects

[Mark <mar...@gm...>]

I just set up my own forum, and am attempting to sort a user's subscriptions
by the last post in each thread(BBTopic). However the sorted function is 
failing saying lambda only takes 1 argument but was given 2. I use this
sorted function on lists of non SQLObject objects and it works fine for me.

Can you use sorted with a list returned from a select? 

Or is there a way for me to rewrite this? Perhaps using orderBy?
 

        subs_sel = list(BBSubs.select(BBSubs.q.user_id==1))
        for sub in subs_sel:
            sub.topic = BBTopic.get(sub.topic_id)
            sub.post  = BBPost.get(sub.topic.last_post_id)
            sub.forum = BBForum.get(sub.topic.forum_id)
          
        subs = sorted(subs_sel, lambda x: x.topic.last_post_id)
