A Tornado App Example Using PyEnty

Here’s a simple example of how to create a tornado application with pyenty

from tornado.gen import coroutine
import tornado.httpserver
import tornado.ioloop
import tornado.web

from pyenty import EntityConnection, EntityManager
from pyenty.types import Entity, Str, List


class Profile(Entity):
    name = Str()

    def __init__(self, name):
        self.name = name


class User(Entity):
    name = Str()
    last_name = Str()
    profile = List(Profile)

    def __init__(self, name='', last_name=''):
        self.name = name
        self.last_name = last_name

    def add_profile(self, profile):
        self.profile.append(profile)


class UserHandler(tornado.web.RequestHandler):
    emanager = None

    @coroutine
    def post(self):
        self.emanager = EntityManager(entity=User)
        name = self.get_argument('name')
        last_name = self.get_argument('last_name')

        # add user
        user = User(name, last_name)
        user.add_profile(Profile('guest'))
        object_id = yield self.emanager.save(user)


    @coroutine
    def get(self):
        emanager = EntityManager(User)
        user = yield emanager.find()


EntityConnection.open(db="ym_db_test")
if __name__ == "__main__":

    app = tornado.web.Application(
        [(r'/user', UserHandler), ],
        autoreload=True
    )

    app.listen(8889)
    tornado.ioloop.IOLoop.instance().start()
