I'm useing peewee with my tornado webapp,when I read peewee's document,I found:
Adding Request Hooks
When building web-applications, it is very important that you manage your database connections correctly. In this section I will describe how to add hooks to your web app to ensure the database connection is handled properly. These steps will ensure that regardless of whether you're using a simple SQLite database, or a pool of multiple Postgres connections, peewee will handle the connections correctly.

Insides,it tells how Flask Django Bottle ...to use that except the solution for Tornado
I wonder it's a easy way for tornado to solve this problem? Or this doesn't matter at all?
The idea there is that you want to open a connection when a request begins, and close it when the request is finished (the response is returned).
To do this it looks like you can subclass RequestHandler
:
from tornado.web import RequestHandler
db = SqliteDatabase('my_db.db')
class PeeweeRequestHandler(RequestHandler):
def prepare(self):
db.connect()
return super(PeeweeRequestHandler, self).prepare()
def on_finish(self):
if not db.is_closed():
db.close()
return super(PeeweeRequestHandler, self).on_finish()
