Stuck on regex

Hi,

I can't seem to figure out how to format the regex in one of these challenges correctly. I want to achieve the expression "/article/<pk>" in the last row below. Can anyone see what I am doing wrong?

Thanks!

articles/views.py 
from django.shortcuts import render

from .models import Article, Writer


def article_list(request):
    articles = Article.objects.all()
    return render(request, 'articles/article_list.html', {'articles': articles})


def writer_detail(request, pk):
    writer = Writer.objects.get(pk=pk)
    return render(request, 'articles/writer_detail.html', {'writer': writer})

def article_detail(request, pk):
    article = Article.objects.get(pk=pk)
    return render(request, 'articles/article_detail.html', {'article': article})
articles/urls.py 
from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'writer/(?P<pk>\d+)/$', views.writer_detail),
    url(r'', views.article_list),
    url(r'article/(?<pk>\d+)/$', views.article_detail),
]

Hi Christofer

You need to add the urls in this order. Strange the way django's url work, i had an issue like this on my project i am building now and spent hours trying to work out what the problem was.

So i try to keep all urls together. /category/12 /category/51 /search /about / # home directory.

urlpatterns = [
    url(r'writer/(?P<pk>\d+)/$', views.writer_detail),
    url(r'article/(?P<pk>\d+)/$', views.article_detail),  
    url(r'article/', views.article_list),

]

may be someone one else would know what django urls are so temptramental.

Hi Andreas,

That worked like a charm. Thanks a lot! So I take it that I should put the longest URL first and then add each shorter after that. That would have taken a while to figure out. Anyway, thanks !
