Django contenttypes follow/unfollow

Попытка использовать contenttypes для хранения следующих отношений пользователей.

Я могу создать слежку, но не могу удалить слежку из базы данных.

Код модели

accounts app
------------
from activities.models import Activity

class CustomUser(AbstractUser):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    follow = GenericRelation(Activity)


activities app
--------------
class Activity(models.Model)
    FOLLOW = 'F'
    LIKE = 'L'
    ACTIVITY_TYPES = [
        (FOLLOW, 'Follow'),
        (LIKE, 'Like'),
    ]

    ## stores the user_id of the Liker/Follower
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)

    ## stores 'F' or 'L'
    activity_type = models.CharField(max_length=2, choices=ACTIVITY_TYPES)

    date = models.ForeignKey(ContentType, on_delete=models.CASCADE)

    ## stores CustomUser id of the user who is followed or the id of the post that is liked
    object = models.UUIDField(null=True, blank=True, db_index=True)

    content_object = GenericForeignKey('content_type', 'object_id')

    class Meta:
       indexes = [models.Index(fields=["content_type", "object_id"]),]

View Code

follower = User.objects.get(id=follower_id)
followed = User.objects.get(id=followed_id)

## This is the contenttypes model
a = Activity.objects.filter(user=follower.id, object_id=followed.id)

## This is my janky way of checking whether the follower is already following the followed
if len(a) == 0:
    ## This works to create a follow
    followed.follow.create(activity_type=Activity.FOLLOW, user=follower)

Я подумал, что это может сработать, чтобы удалить follow

followed.follow.remove(a)

но он выдает ошибку 'Объект QuerySet' не имеет атрибута 'pk'
