How can I model the "popularity" concept in code?

I am building a tags Django application to display a feed of tags ranked by "popularity."

Currently, my Tag model in models.py looks like this:

class Tag(models.Model):
    tag = models.CharField(max_length=64, unique=True)
    slug = models.SlugField(max_length=64, unique=True)

Ultimately, I would like to query tags in my index view in views.py kind of as follows:

def index(request):
    context = {"tags": Tag.objects.order_by("popularity")}
    return render(request, "tags/index.html", context)

How can I model the "popularity" concept in code?

Should I add a popularity field to the Tag model and basically count how many times a tag has been used, or is there a better, slicker way to achieve the same result?

django-taggit

You can implement django-taggit or read the docs then you will get an idea how tag can be implemented in django.

Happy Coding :)

#models.py

class Tag(models.Model):
    tag = models.CharField(max_length=64, unique=True)
    slug = models.SlugField(max_length=64, unique=True)
    
    @property
    def popularity(self):
         return self.foo_set.count()



class Foo(models.Model):
    tag = models.ManyToManyField(Tag, blank=True)

#views.py

def index(request):
    context = {"tags": sorted(Tag.objects.all(), key=lambda x: x.popularity, reverse=True)}
    return render(request, "tags/index.html", context)

#html

{% for tag in tags %}
    {{ tag.tag }} - {{ tag.popularity }}
{% empty %}
    No Tags
{% endfor %}
