Django1.11升级到Django2.2.14
1、django自带的认证系统
报错：
修改：
if user.is_authenticated:
2、url include模块
报错：
1) url(r'^admin/', include(admin.site.urls))
'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.2) url(r'^', include('applications.web.urls', app_name='web', namespace='web'))
TypeError: include() got an unexpected keyword argument 'app_name'
修改：
1) url(r'^admin/', admin.site.urls)
2) url(r'^', include(('applications.web.urls', 'web'), namespace='web'))
3、 middleware中间件
报错：
MIDDLEWARE_CLASS = (

'django.contrib.auth.middleware.AuthenticationMiddleware',
