because the HttpResponse is not returned the login_view call does nothing.
if your user is logged in then any request should automatically contain that user. so, for example:
if request.user.is_authenticated():
user = request.user
context['user'] = user.username
otherwise you could pass the user in the url and then get the username in the view (or just use the user object in the template and insert {{ user.username }} into your template.
