Django tracking of viewed posts?

Question

Django

Hello!
It is necessary to implement the account of viewed posts for each user, I implement models.py like this:

class CountArticle(models.Model):
    user = models.OneToOneField(User)
    count = models.ManyToManyField(Article)

Added a new table with links between each user and articles.
This initialization takes place here context_processors.py:

def total_count(request):

    def init_count(request):
        #  add to CountArticle model Article list
        count = CountArticle.objects
        usr = request.user
        art = Article.objects.all()
        art_add = Article.objects
        count.create(user=usr)
        count = CountArticle.objects.get(user=usr)
        for x in art:
            count.count.add(art_add.get(article_title=x))
        return {"total_count": len(count.count.all()), }

    if request.user.is_authenticated():
        try:
            total = CountArticle.objects.get(user=request.user)
            return {"total_count": len(total.count.all()), }
        except ObjectDoesNotExist:
            return init_count(request)
    return {}

The essence of the problem: I register a user, the initialization of my viewed articles occurs on the first count request, i.e. almost immediately after registration, and now I have added 20 articles and it seems to me that it all starts to be processed for a very long time, but what if I have 1000 articles?
Please tell me the options for implementing this function, or maybe the approach is correct, but I'm doing something wrong?
