This has been significantly changed in Django 3, this could be done like this: path('/', views.article_detail), where the first slug "" is the name of the parameter which could be any name; "abc", "the_slug", etc. If you still insist on using regex then there is one thing to change; the method name instead of "url" use "re_path": re_path(r'^(?P[\w-]+)/$', views.article_detail),

[@EzanAsifEB_]

thanks bro re_path worked for me but not the first one don't know why

You are a brilliant instructor. Absolutely perfectly paced. Clean presentation. Very easy to listen to your voice for days. Please continue you're amazing channel. Thank you!

[@pushkarsaraf524]

Great tutorial, for Django 2 and above, URL dispatching or URL capturing using RegEx --> make sure you import ' re_path from 'django.urls ' and use ' re_path( ... ) ' inside ' urlpatterns '.

@@positivemindalways why cant i just use the new django 3 URL capturing scheme? path('', views.article_detail), ?

This may help you with Django 3 -> path('/', views.article_detail)

[@kalekber]

django v2: urlpatterns = [ path('', views.article_list), path('/', views.article_detail) ]

good, it is useful

thanks man

[@matooj1775]

If anyone has problems with the slug thing just try this: path('/', views.article_detail) it worked for me so try it out if you want

[@alphonseraynaud976]

I actually came up with my own solution to this earlier in this tutorial: in urls.py I wrote: for article in Article.objects.all(): urlpatterns.append(path(f'{article.slug}/',views.article_details)) and then in views.py: def article_details(request): for a in Article.objects.all(): if "/"+a.slug+"/" == request.path: article = a return render(request, 'article.html', {'article':article})

Loving the playlist

thx I hope, someday I will watch playlist for Django in production :-)

[@ShaffleOne]

same! @The Net Ninja Please!

[@mustafayilmaz7553]

subscribed, I like your way to show people how it works :)

[@ndifrekeumoren3548]

Thanks for this great tutorial, Shaun. Please, can you update it to version 2.0 as name capturing group is quite different? thanks once again looking forward to the update

[@luckyluke5257]

It looks like a new version of Django 2.0 has come out, and now you can add it using PATH, not URL. How to do it now?

[@peymannaji]

We need to import re_path in urls.py : from django.urls import path, re_path And then you need to add : re_path('(?P[\w-]+)/$', views.article_detail),

[@wisamkhalid5663]

thanks

[@therhythmatic]

I ended up doing something like path('/', views.article_detail) which gave me desirable results.

[@amadeuscam1]

path("/", views.article_detail)

[@ayushbharadwaj2536]

thank you , it worked

[@pyuc]

2:40 does the name have to be "request" or can you choose a different one

[@010101dddm]

why am i getting 404 error? from django.urls import path, re_path from . import views urlpatterns = [ path('', views.index), re_path('', views.article_detail) ]

[@lawrencekipchumba2987]

path('/', views.article_detail)

[@user-pb2mn7go2p]

Shaun typed the urls BY HAND. 7:04 The links on the homepage still refer to .../article/# and don't even match our regex so nothing happens.

[@user-pb2mn7go2p]

Django Rules

[@user-pb2mn7go2p]

or in Django code (before render) {{ article.title }}

[@CodeProHassam]

Yes thats make sense but what if we just want to retrieve the article with Article ID in DB ??

[@damerlasrithandhavakrishna5045]

Redirect is not happening It says "reverse for 'list' not found. 'list' is not a valid view function or pattern name"

[@invalidname5720]

Using the URLconf defined in blogtastic.urls, Django tried these URL patterns, in this order: admin/ about/ articles/ articles/ (?P[\w-]+)/ ^static/(?P.*)$ The current path, articles/hello, didn't match any of these. I'm getting this error

[@truyenkieuvan9883]

I had done that " url(r'^(?P[\w-]+)/$',views.article_detail)," and "def article_detail(request, slug): return HttpResponse(slug)" but when i had clicked on title of article, nothing happened. Can you give me some reason.

[@truyenkieuvan9883]

I tried it but it doesn't work. Help me please

[@truyenkieuvan9883]

base on video 15, I use "url(r'^/(?P[\w-]+)/$',views.article_detail)" and in article_list.html, I write "{{article.title}}" and it work correctly. Can you explain to me? Thanks so much!

[@Nomadvicky]

{{article.title}} This is also working for the above condition.

[@user-pb2mn7go2p]

it might be way too late but Shaun typed those urls BY HAND. in the templates {{ article.title }} we still didn't change the href="#" part so article titles refer to .../articles/# and not to .../articles/django-rules yet there's and an answer from your timeline :D actually. {{ article.slug }} in href="{{ article.slug }}" like this {{ article.title }} works
