I created a simple article/blog app. I am having problem in detail view. I created a list view of articles and also created a detail view if someone clicks on one of the acrticle , it takes the to detail view of article .
But when i click on one of the articles , i am getting above error stated in the title. It is also pointing the error location to
this code {% url "detail" post.id %} which u can see in 44th or 45th line in Error page i posted in the last.
I tried lots of thing , none worked.
I posted all my project files below. you can have look.
I would be glad if you guys helps me.
My code goes here :
Views.py
from django.shortcuts import render , redirect , get_object_or_404
from django.shortcuts import render , redirect , get_object_or_404
from .models import Article , members
from django.views.generic import ListView , DetailView
from .forms import create_form

model = Article
template_name = "article.html"
context_object_name = "articles"
def post_creator(request):
if request.method == "POST":
form = create_form(request.POST)
if form.is_valid():
form.save()
return redirect("/blog/home/")
else:
form = create_form()
return render(request , "post_create.html" , {"form":form})
def registration(request):
if request.method == "POST":
form = members(request.POST)
if form.is_valid():
form.save()
return redirect("/blog/home/")
else:
form = members()
return render(request , "register.html" , {"form":form})
class post_detail_view(DetailView):
model = Article
template_name = "detail.html"
urls.py
from django.conf.urls import url
from . import views
from django.contrib.auth.views import LoginView , LogoutView
urlpatterns = [

You're confusing the URL syntaxes. url() takes a regex; for the new-style format you need to use path().
path("article/<int:pk>/" , views.post_detail_view.as_view() , name="detail"),
