Change likedislike to only like

django, Django

In other project, I try to create only like reaction from likedislike app.

I try to change view, model and urls on this but I have atrribue error:
AttributeError at /like/embed/1/

'Embed' object has no attribute 'create'

class VotesView(View):
    model = None    # Data Model - Articles or Comments

    def post(self, request, pk):
        obj = self.model.objects.get(pk=pk)
        # GenericForeignKey does not support get_or_create
        try:
            like = Like.objects.get(content_type=ContentType.objects.get_for_model(obj), object_id=obj.id, user=request.user)
            if like:
                result = True
            else:
                like.delete()
        except Like.DoesNotExist:
            obj.create(user=request.user)
            result = True

        return HttpResponse(
            json.dumps({
                "result": result,
                "like_count": obj.votes.count(),
            }),
            content_type="application/json"
        )

Model:

class Like(models.Model, Activity):

    user = models.ForeignKey(User, verbose_name='uzytkownicy', on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey()

Urls:

    path('embed/<pk>/',
        login_required(views.VotesView.as_view(model=Embed)),
        name='embed_like'),

Any idea how to solve this?

Hello,
I think you need rewrite row 14, like this

obj.votes.create(user=request.user)
