我正在尝试创建一个收藏夹功能，用户可以将其他用户添加为收藏夹。在显示用户配置文件的视图中，我有一个按钮，可以添加用户或删除已添加的用户。问题是，我无法将添加为收藏夹的用户传递到视图。
models.py

class User(AbstractUser):
    is_type1 = models.BooleanField(default=False)
...

class Type1(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    favorite = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, related_name='favorite')

views.py

def FavoriteView(request, pk):
    current_user = request.user
    Type1.user = current_user.id
    buser = Type1.user
    Type1.favorite = get_object_or_404(User, id=request.POST.get('username'))  # The of the error where I try to add the user being added as a favorite
    fuser = Type1.favorite
    if Type1.favorite.filter(id=request.user.id).exists():
        Type1.favorite.remove(request.user)
    else:
        Type1.favorite.add(request.user)

    return HttpResponseRedirect(reverse('profile-details', kwargs={'username': Type1.favorite}))

class UserView(DetailView):
    model = User
...
    template_name = 'users/profile-details.html'

    def get_context_data(self, **kwargs):
        data = super().get_context_data(**kwargs)
        favorite_connected = get_object_or_404(Type1.favorite, id=self.kwargs['username'])  # The of the error where I try to add the user being added as a favorite
        favorite = False
        if favorite_connected.favorite.filter(id=self.request.user.id).exists():
            liked = True
        data['user_is_favorite'] = favorite
        return data

    {% if user.is_authenticated %}
