What information was incorrect, unhelpful, or incomplete?

in the example, it gets the value of num_visits and updates the value in session, while in the context, the value has not been updated

What did you expect to see?

def index(request):
    ...

    num_authors=Author.objects.count()  # The 'all()' is implied by default.

    # Number of visits to this view, as counted in the session variable.
    num_visits=request.session.get('num_visits', 0)
    request.session['num_visits'] = num_visits+1
    
    

    updated_num_visits = request.session.get('num_visits')


    # Render the HTML template index.html with the data in the context variable.
    return render(
        request,
        'index.html',
        context={'num_books':num_books,'num_instances':num_instances,'num_instances_available':num_instances_available,'num_authors':num_authors,
            'num_visits':updated_num_visits}, # use updated_num_visits
    )

The issue targets zh-CN but it appears to be a problem in en-US too.

Thank you.

This was intentional. I was reading it as "the number of times you have visited this page before" - which is initially zero, and iterates up.
Appreciate that is ambiguous, and also that most users would assume this includes the current visit.

I've fixed it by iterating num_visits, storing it in the session variable, then displaying it - I like this, because what is displayed matches the session variable.

ENGLISH fix is in mdn/content#35423

@bsmth How do we move this to the translation area(s), which may all be wrong?

Here's the diff:

-    request.session['num_visits'] = num_visits + 1
+    num_visits += 1
+    request.session['num_visits'] = num_visits

It's in the following places:

zh-tw/learn/server-side/django/sessions/index.md:    request.session['num_visits'] = num_visits + 1
pt-br/learn/server-side/django/sessions/index.md:    request.session['num_visits'] = num_visits + 1
ko/learn/server-side/django/sessions/index.md:    request.session['num_visits'] = num_visits + 1
es/learn/server-side/django/sessions/index.md:    request.session['num_visits'] = num_visits + 1
