[Answered ]-NoReverseMatch at / error when implementing a comment option

I have solved my problem !
I needed to change the way i was calling my url as it was the old way.

 path('post/<int:pk>/', core_views.post_detail, name='post-detail')

This was the correct way to do it.

First, the last tag has the post detail URL but without the required integer variable.

Second, you shouldn’t loop through posts because it is a single object.

Third, according to the view you are showing, there is no context variable named ‘posts’. It’s post.
