Since I figured out the problems here with some help on #turbogears IRC
I thought a reply to my own question was in order. Here is how I got
grabbed the identity of the current user and used it to populate the
session dict. In this controller 'User' is the standard User model you
get when you invoke a new project with Identity. I added a few columns
to it to customize for my own needs and have made comments in the code
to that effect.
def index(self):
"""initialize session dict with user's fs paths, populate
session with virtualized file system (vfs) dict"""
UserObj = User.get(identity.current.user.id)
source_uri = UserObj.source_uri #I added this column to the
User model
albums_uri = UserObj.albums_uri #same with this column
#log.debug(albums_uri), log.debug(source_uri)
FS = FSHandler() #plug in the FSHandler class
cherrypy.session['source_entries'] = FS.vfs(source_uri)
cherrypy.session['albums_entries'] = FS.vfs(albums_uri)
return dict()
In my app the user hits the index page once - never to return, so just
hitting the index controller when the user logs in instantiates the
session variables. Of course an app where the user returns to index a
lot you would want to check to see if the session's key was already
there and update it if it was instead of overwriting as this function
does. Sessions are a very powerful feature of turbogears and key to
making it work in a multiuser scenario.
