Are you sure you are not logged in? If you assign a local variable to the
value of request.user before trying the get then when you get the debug page
you can see the user value among the local variables. If it's a
django.contrib.auth.models.AnonymousUser, then somehow you got past the
@login_required without logging in. I think it's more likely you are logged
in and no Meetingtime matching your user exists. (Also, are you sure you
want a get there? Using get implies there will be exactly one Meetingtime
per user, otherwise the get will raise an exception.)
