class Handler(tornado.web.RequestHandler):

    def db(self):
        if not hasattr(self, '_db'):
            self._db = asyncmongo.Client(pool_id='mydb', host='127.0.0.1', port=27017, maxcached=10, maxconnections=50, dbname='test')
        return self._db

    @tornado.web.asynchronous
    def get(self):
        self.db.users.find({'username': self.current_user}, limit=1, callback=self._on_response)
        # or
        # conn = self.db.connection(collectionname="...", dbname="...")
        # conn.find(..., callback=self._on_response)

    def _on_response(self, response, error):
        if error:
            raise tornado.web.HTTPError(500)
        self.render('template', full_name=respose['full_name'])

About

Features not supported: some features from pymongo are not currently implemented. i.e.: directly interfacing with indexes, dropping collections, and retrieving results in batches instead of all at once. (asyncmongo's nature means that no calls are blocking regardless of the number of results you are retrieving)

Requirements

The following two python libraries are required

pymongo version 1.9+ for bson library
tornado
