    'title': 'title',

# update
comment = {
    'commentor': DBRef(UserDocument.meta['collection'], alice_id),
    'contents': 'I am comments.'
yield PostDocument.update({'_id': post_id},
                          {'$push': {'comments': comment}})

# query
user = yield UserDocument.find_one({'name': 'Bob'})
posts = yield PostDocument.find().to_list(5)

# higher API
user_list = yield UserDocument.get_user_list()
