python - 动态扩展 urlpatterns

Question

我有应用程序 app1。它已连接（通过INSTALLED_APPS）app2；假设 app2 对我来说是某种黑盒。但我知道它的网址中的 app2 有一些 i18n_patterns。
我需要包含从 app2 到我的 app1的所有url。并将它们包含在根位置：

urlpatterns = ('',
    (r'', include("app1.urls")),
    (r'', include("app2.urls")),
)

因为 app2.urls 中的 i18n_patterns 这样include会在这里
ImproperlyConfigured('Using i18n_patterns in an included URLconf is not allowed.')
引发源代码

有没有办法在不了解它们的情况下将所有 urlpatterns 附加app2.urls到 my urlpatterns？

For instance, you can from app2.urls import urlpatterns as urlpatterns2 and later in your urls.py at the end do this:

urlpatterns += urlpatterns2
# or maybe: 
# urlpatterns += urlpatterns2[1:] if you don't want to include the initial attribute

This behaves like a normal list concatenation and might work.

Note: This is a bit of hackery to overcome the include limitants. If there is a better way to do this I'll love to know.

Hope this helps!
