python之django 1.11.x 升级到 2.0 时出现 urls 错误

我正在将我的项目从 django 1.11.x 迁移到 2.0。在我到达网址之前，我一切顺利。我碰巧有这样的导入

从 cashondelivery.dashboard.app 导入应用程序作为 cod_app

我的 url 模式为

url(r'^dashboard/cod/', include(cod_app.urls)), 

但我的终端出现以下错误

url(r'^dashboard/cod/', include(cod_app.urls)), 
  File ".../dev/lib/python3.6/site-packages/django/urls/conf.py", line 27, in include 
    'provide the namespace argument to include() instead.' % len(arg) 
django.core.exceptions.ImproperlyConfigured: Passing a 3-tuple to include() is not supported. Pass a 2-tuple containing the list of patterns and app_name, and provide the namespace argument to include() instead. 

我真的很感激修复。

cashondelivery->dashboard->app

import django 
from django.conf.urls import url 
from django.contrib.admin.views.decorators import staff_member_required 
 
from oscar.core.application import Application 
 
from . import views 
 
 
class CashOnDeliveryDashboardApplication(Application): 
    name = None 
    default_permissions = ['is_staff', ] 
 
    list_view = views.TransactionListView 
    detail_view = views.TransactionDetailView 
 
    def get_urls(self): 
        urlpatterns = [ 
            url(r'^transactions/$', self.list_view.as_view(), 
                name='cashondelivery-transaction-list'), 
            url(r'^transactions/(?P<pk>\d+)/$', self.detail_view.as_view(), 
                name='cashondelivery-transaction-detail'), 
        ] 
 
        if django.VERSION[:2] < (1, 8): 
            from django.conf.urls import patterns 
 
            urlpatterns = patterns('', *urlpatterns) 
 
        return self.post_process_urls(urlpatterns) 
 
 
application = CashOnDeliveryDashboardApplication()  

请您参考如下方法:

您需要删除 include() 并直接传递 urls:

url(r'^dashboard/cod/', cod_app.urls), 

urls 属性 returns a 3-tuple ，而不是 urlpatterns 的列表，并且在 Django 2 中删除了将其传递给 include() 的支持。
