Like

I am trying to use Ajax to submit a like button, I believe everything
is in order but I keep getting django.urls.exceptions.NoReverseMatch:
Reverse for 'like_post' with arguments '('',)' not found. 1 pattern(s)
tried: ['score/like/(?P[0-9]+)$']
I am not sure what is the reason. Need help to identify the error.
Here is the view
class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"
def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
stuff = get_object_or_404(Post, id=self.kwargs['pk'])
total_likes = stuff.total_likes()
liked = False
if stuff.likes.filter(id=self.request.user.id).exists():
liked = True
context["total_likes"] = total_likes
context["liked"] = liked
return context
def LikeView(request, pk):
# post = get_object_or_404(Post, id=request.POST.get('post_id'))
post = get_object_or_404(Post, id=request.POST.get('id'))
like = False
if post.likes.filter(id=request.user.id).exists():
post.likes.remove(request.user)
like = False
else:
post.likes.add(request.user)
like = True
context["total_likes"] = total_likes
context["liked"] = liked
if request.is_ajax:
html = render_to_string('like_section.html', context, request=
request)
return JsonResponse({'form': html})
Here is the url.py updated
urlpatterns = [
path('user/', UserPostListView.as_view(), name=
'user-posts'),
path('', PostListView.as_view(), name='score'),
path('who_we_Are/', who_we_are, name='who_we_are'),
path('/', PostDetailView.as_view(), name='post-detail'),
path('like/', LikeView, name='like_post'),
path('new/', PostCreateView.as_view(), name='post-create'),
path('/update/', PostUpdateView.as_view(), name=
'post-update'),
path('/delete/', PostDeleteView.as_view(), name=
'post-delete')
]
here is the template
{% csrf_token %}
Likes: {{total_likes}}
{% if user.is_authenticated %}
{% if liked %}
>>> 'post_id' class= "btn btn-danger btn-sm"
value="{{post.id}}"> Unlike
{% else %}
>>> 'post_id' class= "btn btn-primary btn-sm"
value="{{post.id}}"> Like
{% endif %}
{% else %}
>>> > Login to Like
{% endif %}
here is the ajax
