[Иоанн]

Здравствуйте

реализую функционал лайков, дизлайков на django, но кнопка не срабатывает.Не могу удалить лайк.

<form action="{% url 'forum:like-topic'  %}" method="POST">
    {% csrf_token %}

<input type='hidden' name='topic_id' value="{{ topic.id }}">
{% if user not in topic.likes.all %}
    <button class="ui button positive" type="submit">Like</button>
{% else %}
    <button class="ui button negative" type="submit">Unlike</button>

{% endif %}
    <strong>{{ topic.likes.all.count }} likes </strong>

</form>

views.py
views.py
    def like_topic(request):

user = request.user
if request.method == 'POST':
    topic_id = request.POST.get('topic_id')
    topic_obj = Topic.objects.get(id=topic_id)
    if user in topic_obj.likes.all():
        topic_obj.likes.remove(user)

    else:
        topic_obj.likes.add(user.id)
    like, created = Like.objects.get_or_create(user_id=user.id, topic_id=topic_id)
    if not created:
        if like.value == 'Like':
            like.value = 'Unlike'
        else:
            like.value = 'Like'
        like.save()

return HttpResponseRedirect(reverse('forum:topic_detail', kwargs={'slug': topic_id}))
