Django2.0 配置url

以《跟老齐学Python Django实战》为例

在mysite/setting.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('blog/', include('blog.urls', namespace='blog'))
]

在blog/urs.py

from django.urls import path
from . import views
app_name = 'blog'

urlpatterns = [
    path('', views.blog_title, name='blog_title'),
    path('<int:article_id>/', views.blog_article, name='blog_article')
]
