another way of expressing the same User.select({ User: ['*'], Tweet: [Count('id', 'count')] }).group_by('id').join(Tweet).order_by(('count', 'desc')) # do an atomic update TweetCount.update(count=F('count') SELECT "id", "creator", "name" FROM "blog" WHERE "id" = ? LIMIT 1 PARAMS: [1] To delete an arbitrary group of records, you can issue a DELETE query. The following will delete all Entry objects that are a year equivalent to the following: query = Blog.select({ Blog: ['*'], Entry: [Count('id')], }).group_by(Blog).join(Entry) The resulting query will return Blog objects with all their normal attributes
