Ok, I understand. I create a session variable with session.my_var = "some content"
but not with session['some_id'] = "some content" (web2py will raise an exception if the session variable does not exists), and I get the content with another_var = session.my_var or another_var = session['my_var'] Anyway, my_var is a hard coded key in this situation. I cannot create dynamically session variables. I think this is not a good practice. All other frameworks and django also do this. http://www.djangobook.com/en/2.0/chapter14/ ------------------------------------------------------ # Set a session value: request.session["fav_color"] = "blue" ------------------------------------------------------ ionel On May 9, 12:49 pm, Thadeus Burgess <thade...@thadeusb.com> wrote: > session['views'] = views is valid.
