Tornado Session in Redis

I am writi开发者_StackOverflow中文版ng a lightweight Tornado based comet server. I would like to store the "self" object in redis to maintain the state.. Will this work?

For a start, i cant even serialize self to be stored in Redis..

This is the error

File "sessionsupport.py", line 27, in get
    this = cPickle.dumps(self,1)
  File "/home/test/lib/python2.7/copy_reg.py", line 70, in _reduce_ex
    raise TypeError, "can't pickle %s objects" % base.__name__
TypeError: can't pickle instancemethod objects

any suggestions on how i would do this?

I'm unsure of if the self object refers to an instance of RequestHandler, or maybe some type of Session instance you have. Whichever it is, you're probably going to want to convert your object to a dict before pickling and saving to redis. At least, that's what I do with MongoDB. My Tornado sessions:

• Are dicts that contain any data I want to persist throughout the users' sessions
• Are assigned an ID which is:
  • Saved along with the dict in my datastore (redis or MongoDB)
  • Stored in a user's cookie
