There's been a fair number of changes to template tags between 1.3 and 1.8, so I wouldn't be surprised if something is slightly off here. > template code > > <div class="question_number pull-left">Q{% counter %}. </div>...<script>var > no_of_questions={{ counter_var }}</script> > > > Have you installed the django-debug-toolbar and inspected the value of the context? It could be that the snippet is no longer updating counter_var in the context correctly. Also make sure that you are using {% counter %} and {{ counter_var }} inside the same set of {% block %} tags, as variable scope does not extend outside of blocks. > Template tag is registered and it prints correctly Q<count>. except > counter_var.

Is there another context variable that contains the list of questions that you are printing? And if so, are you using a {% for %} loop to generate them? If so, I would recommend you use {{ forloop.counter }} rather than trying to track the counts yourself. See the list of variables available inside of {% for %} loops at the end of this section: https://docs.djangoproject.com/en/1.8/ref/templates/builtins/#for > *Note: I asked same question on stackoverflow but no help till now.* > A link to the SO question would be helpful if you want help there, or if someone wants reputation points. -James -- You received this message because you are subscribed to the Google Groups "Django users" group.
