Using double url tag in django - django

Question

I got two urls.py file
first one is for project urls.py
urlpatterns = [
path('admin/', admin.site.urls , name = 'admin'),
path('',homeView, name='home'),
path('post/',post, name='post'),
path('post/',include('post.urls'), name='posturl'),
path('student/',studentM, name = 'student' ),
path('student/',include('student.urls') , name='studenturl'),
]
second one is url for app
urlpatterns = [
path('index', post_index, name = 'index'),
path('details/' + '<int:id>', post_detail, name = 'detail'),
path('create', post_create, name = 'create'),
path('update', post_update , name = 'update'),
path('delete', post_delete , name = 'delete'),
]
I am trying to reach the adress like
:8000/post/details/5
but when i try to use in html
=>> {{post.id}}
=>> {{post.id}}
=>> {{post.id}}
None of these are not working I got 404 error.
How can I reach the link which I want
def post(request):
context = {
}
return render(request,'post/post.html',context)
def post_detail(request,id):
post = get_object_or_404(Post,id=id)
context = {
'post' : post
}
return render(request,"post/details.html",context)

Im assuming that you are tryng to access this url pattern:
path('details/' + '<int:id>', post_detail, name = 'detail'),
which can be written like this:
path('details/<int:id>/', post_detail, name='detail'),
if im correct, you should use this in your html a tag:
text for the link
also, try not to do this:
path('post/',post, name='post'),
path('post/',include('post.urls'), name='posturl'),
it is better practice creating the post view inside your app, and then your urls.py are going to look like this:
# this is the project urls file
...
path('post/', include('post.urls')), # dont need a name here, you are not going to reference this
...
# this is the app urls file
...
path('', post, name='post'), # this is going to accessed as localhost:8000/post
path('index', post_index, name = 'index'),
path('details/<int:id>', post_detail, name = 'detail'), # this is going to accessed as localhost:8000/post/details/the_id_of_the_post
path('create', post_create, name = 'create'),
path('update', post_update , name = 'update'),
path('delete', post_delete , name = 'delete'),
...
