Django как система

Я делаю проект блога, но у меня проблема, я делаю систему лайков на блоге, но она выдает ошибку

def like_post(request):
    user=request.user
    if request.method=='POST':
        post_id=request.POST.get('post_id')
        post_obj= Post.objects.get(id=post_id)

        if user in post_obj.liked.all():
            post_obj.liked.remove(user)
        else:
            post_obj.liked.add(user)

        like,created=Like.objects.get_or_create(user=user,post_id=post_id)

        if not created:
            if like.value=='Like':
                like.value='Unlike'
            else:
                like.value='Like'
        like.save()

    return reverse('main:post_detail') 

path('blog/like', views.like_post, name='like-post'),

class Post(models.Model): liked = models.ManyToManyField(User, default=None, blank=True, related_name='liked')

LIKE_CHOICES = (
    ('Like', 'Like'),
    ('Unlike', 'Unlike')
)

class Like(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    post = models.ForeignKey(Post, on_delete=models.CASCADE)
    value = models.CharField(choices=LIKE_CHOICES, default='Like', max_length=10)
    date_liked = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return str(self.post)

      <form action="{% url 'main:like-post' %}" method="POST">
        {% csrf_token %}
        <input type="hidden" name="post_id" value='{{post.id}}'>
          <button class="btn btn-primary" type="submit"> Like</button>
        <br>
        <strong>{{ post.liked.all.count }} Likes</strong>
      </form>

Это ошибка, которую я получил.
