You can use *global variables, sessions, session._initializer *and
conditions as* if..else*. For example:
In your app.py you should create:
store = web.session.DBStore('database','table_users')
> session = web.session.Session(app, store, initializer={'login': 0,
> 'username': 'default' })
> session_data = session._initializer
# This is a basic example
> # This is only the class login without the render and other variables that
> you need
>
class login:
> def GET(self):
> if session_data['login'] == 1:
> raise web.seeother('/profile')
> else:
> return render.login()
> def POST(self):
> i = web.input()
> m = model.login(i.user, i.pass) # model.py is the conection to db
> that return True or False
> if m:
> session_data['login'] = 1
> session_data['username'] = i.user
> raise web.seeother('/profile')
> else:
> session.login = 0
> return render.login(msg="User or password incorrect")
