Can't get the right view for the Article Detail URL

why do I get an error when for this exercise?

from django.conf.urls import url

from . import views

urlpatterns = [ url(r'^$', views.ArticleView.as_view(), name="list"), url(r'^/(P?<pk>)/$', views.ArticleDetail.as_view(), name="detail"), ]

The error says "didn't get the right view for the Article Detail URL"

articles/urls.py
from django.conf.urls import url

from . import views

urlpatterns = [
     url(r'^$', views.ArticleView.as_view(), name="list"),
     url(r'^/(P?<pk>)/$', views.ArticleDetail.as_view(), name="detail"),
]
articles/views.py
from django.views.generic import ListView, DetailView

from . import models

class ArticleList(ListView):
    model = models.Article

class ArticleDetail(DetailView):
    model = models.Article
articles/templates/articles/article_list.html
<h1>Articles</h1>

<ul>
</ul>
articles/templates/articles/article_detail.html
<h1>Article title</h1>
<p>By: Author name</p>

There are a few errors in the url statements:

  • the view name should be ArticleList instead of ArticleView
  • the url regex for ArticleDetail has the ?P characters reversed, and is missing the actual matching regex \d+

Post back if you need more help. Good luck!!
