Django 1.9 url 包含 AttributeError 'str' 对象没有属性 'regex'

Question

我最近从 Django 1.7 升级到 1.9，并且在使用 include 转换 url 时遇到了一些问题。

我收到错误消息:AttributeError: 'str' object has no attribute 'regex'

urls.py 文件如下:

myapp/urls.py:

from django.conf.urls import url

from myapp.views import IndexView

#app_name = 'myapp'

urlpatterns = [
  url(r'^$', IndexView.as_view(), name='index'),
]

mysite/urls.py:

from django.conf.urls import url, include

urlpatterns = [
  url(r'^myapp/', include('myapp.urls')),

  # Have also tried the following combinations
  #url(r'^myapp/', include('myapp.urls', 'myapp')),
  #url(r'^myapp/', include('myapp.urls'), name='myapp'),

  # This one works
  url(r'^admin/', admin.site.urls),
]

你不应该在这里导入 include from django.conf.urls import url, include 吗？我的意思是，我认为您应该使用 include，而不是使用 import。
