Tutorial 08 - Sessions

Storing session data in CherryPy applications is very easy: cpg.request
provides a dictionary called sessionMap that represents the session
data for the current user. If you use RAM based sessions, you can store
any kind of object into that dictionary; otherwise, you are limited to
objects that can be pickled.

from cherrypy import cpg

class HitCounter:
    def index(self):
        # Increase the silly hit counter
        count = cpg.request.sessionMap.get('count', 0) + 1

        # Store the new value in the session dictionary
        cpg.request.sessionMap['count'] = count

        # And display a silly hit count message!
        return '''
            During your current session, you've viewed this
            page %s times! Your life is a patio of fun!
        ''' % count = True

cpg.root = HitCounter()

cpg.server.start(configFile = 'tutorial.conf')
