How to access session variable in Mako template and Pyramid?

I have this Pyramid view:

def ClientView(request):
    session = request.session
    session['selectedclientid'] = 'test' #selectedclient.id
    session.save()
    return dict(
        logged_in=authenticated_userid(request)
    )

And then in my template I'm just trying something like this:

% if session['selectedclientid'] != None:
                The session has something
            % endif

And this gives me a template error:

    % if session['selectedclientid'] != None:
TypeError: 'Undefined' object has no attribute '__getitem__'

Am I setting the session variable wrong? Am I querying it wrong? Do I even need to make a copy of the request.session object and .save() it in the first place? Couldn't I just do request.session['myvariable'] = 'foo' and set it that way? That still doesn't help me in pulling it back in the template.

request.session is the variable in your template. Not session. This is why you are getting the Undefined exception.

I think I got it. I can still set it like so:

request.session['selectedclientid'] = 'test'

But reading it back worked like this:

% if 'selectedclientid' in request.session:
                The session has something ${request.session['selectedclientid']}
            % endif
