Question

I have an handler in a Python page written following the guide lines of the Tornado web server. I would to bring this handler in an other page, always linked with the main python page of Tornado.

In that way can I create a new page so I can have a nice project and not an unique page of thousand of lines?

Thank you very much.

Answer 1

class BaseHandler(tornado.web.RequestHandler):
    @tornado.web.removeslash
    def get_current_user(self):
         return self.get_secure_cookie("mechtari")
    @property 
    def db(self):
        if not hasattr(BaseHandler,"_db"):
            _db = pymongo.Connection().essog
            return _db
    @property
    def fs(self):
        if not hasattr(BaseHandler,"_fs"):
            _fs = gridfs.GridFS(self.db)
            return _fs

now all what i’ll do will inherit from this handler:

class LoginHandler(BaseHandler):
    def post(self):
    # do a database search, so i need to connect to database, so no need to the database everytime and make the connection.


class AchatsHandler(BaseHandler):
    @tornado.web.authenticated
    def get(self):
        # render me a page that requires a user to be authentificated, so i always use the base handler

and in the url specs, you only precise the name of classes to bind them to urls.

urls = [
(r"/login", handlers.LoginHandler),
(r"/achats/*", handlers.AchatsHandler),
]

and see, there is no BaseHandler in the url dictionnary!
