Django URLs TypeError:对于include(),视图必须是可调用的或列表/元组 [英] Django URLs TypeError: view must be a callable or a list/tuple in the case of include()
问题描述
升级到Django 1.10后,出现错误:
After upgrading to Django 1.10, I get the error:
TypeError: view must be a callable or a list/tuple in the case of include().
我的urls.py如下:
My urls.py is as follows:
from django.conf.urls import include, url
urlpatterns = [
url(r'^$', 'myapp.views.home'),
url(r'^contact/$', 'myapp.views.contact'),
url(r'^login/$', 'django.contrib.auth.views.login'),
]
完整的回溯是:

推荐答案
Django 1.10不再允许您在URL模式中将视图指定为字符串(例如'myapp.views.home'
).
Django 1.10 no longer allows you to specify views as a string (e.g. 'myapp.views.home'
) in your URL patterns.
解决方案是更新您的urls.py
以包括可调用的视图.这意味着您必须将视图导入到urls.py
中.如果您的网址格式没有名称,那么现在是添加名称的好时机,因为使用虚线python路径进行反向操作不再有效.
The solution is to update your urls.py
to include the view callable. This means that you have to import the view in your urls.py
. If your URL patterns don't have names, then now is a good time to add one, because reversing with the dotted python path no longer works.
from django.conf.urls import include, url
from django.contrib.auth.views import login
from myapp.views import home, contact
urlpatterns = [
url(r'^$', home, name='home'),
url(r'^contact/$', contact, name='contact'),
url(r'^login/$', login, name='login'),
]
如果有很多视图,则不方便将其单独导入.一种替代方法是从您的应用程序导入视图模块.
If there are many views, then importing them individually can be inconvenient. An alternative is to import the views module from your app.
from django.conf.urls import include, url
from django.contrib.auth import views as auth_views
from myapp import views as myapp_views
urlpatterns = [
url(r'^$', myapp_views.home, name='home'),
url(r'^contact/$', myapp_views.contact, name='contact'),
url(r'^login/$', auth_views.login, name='login'),
]
请注意,我们已经使用了as myapp_views
和as auth_views
,这使我们能够从多个应用程序导入views.py
而不会发生冲突.
Note that we have used as myapp_views
and as auth_views
, which allows us to import the views.py
from multiple apps without them clashing.
请参见 Django URL调度程序文档有关urlpatterns
的更多信息.
See the Django URL dispatcher docs for more information about urlpatterns
