Re: path('posts/(?P[0-9]+)/$'

path('posts/<int:post_id>/$') should work as well.

I am new to django so I am not sure I understand what you are saying. Can you give me a rewrite of the correct syntax of the line that is not correct?

Thank you

Hi.

Path is a new url format which uses format of <parser:variable> for exanple like <int:path> . If you want to use regular expressions use re_path instead.

When I run http://localhost:8000/posts/2

I get the error:

      Using the URLconf defined in blog.urls,
      Django tried these URL patterns, in this order:
     

1. admin/
   
2. 
   
3. Posts/(?P<post_id>[0-9]+)/$
   
4. ^media/(?P<path>.*)$
    The current path, posts/2, didn't match any of these.

Here is my .py's

from django.contrib import admin
from django.urls import path
from posts import views
from django.conf.urls.static import static
from django.conf import settings

urlpatterns = [
                  path('admin/', admin.site.urls),
                  path('', views.home),
                  path('posts/(?P<post_id>[0-9]+)/$', views.post_details),

              ] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

views.py

from django.shortcuts import render
from posts.models import Post

# Create your views here.
def home(request):
    posts = Post.objects.order_by('pub_date')

    return render(request, 'posts/home.html', {'posts': posts})

def post_details(request, post_id):
    return render(request, "posts/posts_detail.html", {'post_id': post_id})

Any ideas why it doesn't work. I am a newbie with django
