`include()`：包含其他 URLconf 模块。 用法 ---- - include 一个模块 - include 一个变量 ~~~ # in URLconf 包含一个模块 from django.urls import include, path urlpatterns = [ # ... snip ... path('community/', include('aggregator.urls')), path('contact/', include('contact.urls')), # ... snip ... ] ~~~ ~~~ # in URLconf 包含一个变量 from django.urls import include, path from apps.main import views as main_views from credit import views as credit_views extra_patterns = [ path('reports/', credit_views.report), path('charge/', credit_views.charge), ] urlpatterns = [ path('credit/', include(extra_patterns)), ] ~~~ #### 第二种方式可以用来去除 URLconf 中的冗余。如： ~~~ # in URLconf from django.urls import path from . import views urlpatterns = [ path('<page_slug>-<page_id>/history/', views.history), path('<page_slug>-<page_id>/edit/', views.edit), path('<page_slug>-<page_id>/discuss/', views.discuss), path('<page_slug>-<page_id>/permissions/', views.permissions), ] ~~~ 去除冗余： ~~~ # in URLconf from django.urls import include, path from . import views urlpatterns = [ path('<page_slug>-<page_id>/', include([ path('history/', views.history), path('edit/', views.edit), path('discuss/', views.discuss), path('permissions/', views.permissions), ])), ] ~~~ include 参数传递 --------- 子 URLconf 会收到父 URLconf 捕获的所有参数。 如，以下示例中捕获的 `<username>` 会被正确传递： ~~~ # In settings/urls/main.py from django.urls import include, path urlpatterns = [ path('<username>/blog/', include('foo.urls.blog')), ] # In foo/urls/blog.py from django.urls import path from . import views urlpatterns = [ path('', views.blog.index), path('archive/', views.blog.archive), ] ~~~
