How To Make A Django Follower System

In a recent project i worked on, i needed a way to implement a follower system, after searching the net and not getting any concrete information on making a follower system. i decided to write my own after i finish making the system on my own.
So lets move forward, i assume that you already have a django project started and you are using a custom profile class
open the models.py file of the login/authentication app and paste the below

class Followers(models.Model):
follower = models.ForeignKey(settings.AUTH_USER_MODEL,related_name='follower')
 following = models.ForeignKey(settings.AUTH_USER_MODEL,related_name='following')

def __str__(self):
        return '{} followers {}'.format(self.follower, self.following)

in the userprofile class append these functions to the end of the models

    def get_followers(self):
        get_follower = Followers.objects.filter(follower__pk=self.user.pk)
        followers = []
        for followers in get_follower:
            followers.append(followers.follower)
        return followers

    def get_followers_count(self):
        followers_count = Followers.objects.filter(followers__pk=self.user.pk).count()
        return followers_count

def get_following(self):
        get_following = Followers.objects.filter(following__pk=self.user.pk)
        followings = []
        for followings in get_following:
            followers.append(followings.following)
        return following

    def get_followings_count(self):
        following_count = Followers.objects.filter(following__pk=self.user.pk).count()
        return following_count

then to use it in the template
to get followers count

{{ user.profile.get_follower_count   }}
