Sorry if this is a newbie question, but I'm having trouble figuring
out session management in pylons using the built in beaker module.

I am attempting to do session management and authentication using the
following:

class BaseController(WSGIController):

   requires_auth = False

   def __before__(self):

       # set up the session management
       self = SessionMiddleware(self, key="mykey",
secret="randomsecret")

       # Authentication required?
       if self.requires_auth and 'user' not in self.session:
           # Remember where we came from so that the user can be sent
there
           # after a successful login
           self.session['path_before_login'] = request.path_info
           self.session.save()
           return redirect_to(h.url_for(controller='login'))

To use sessions, merely ensure that at the top of your module you have:
from pylons import session



Cheers,

SessionMiddleware is WSGI middleware, which means it runs in the middleware stack in your projects config/middleware.py. You're not supposed to be setting it up per request on your controller, its already running in the middleware stack, so you can just use the session via the Pylons global. Then just use 'session' in your controller as you did (minus the 'self.' bit). Have you read pylonsbook.com? I believe it goes into this a bit more.
