Question

我将我的Django版本演变为1.9（在我拥有1.6或1.7之前），所以我修改了很多obseltes的东西......

但我的urls.py中的这些行有问题：

import django
import main_app 
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView, ListView
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from main_app.views import *
from main_app.views import password_reset_confirm
... # many urls
url(r'^authentification/$', django.contrib.auth.views.login),
url(r'^forget/send/$', django.contrib.auth.views.password_reset_done),
url(r'^password/$', django.contrib.auth.views.password_reset),
url(r'^password_forget/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$', main_app.views.password_reset_confirm),
url(r'^password-init/$', django.contrib.auth.views.password_reset_complete),

当我编写“python manage.py runserver”时出现此错误：

Unhandled exception in thread started by <function wrapper at 0x7f5bcf01af50>

url(r'^authentification/$', django.contrib.auth.views.login),
NameError: name 'django' is not defined

我不明白为什么我只有这5个网址有问题？！

感谢的

该代码没有显示您导入django：它会显示您在其下方导入元素，但从不会导致名称本身。 Python的基本原则是您必须导入或定义您使用的每个名称。在您的情况下，顶部的import django会起作用，但请注意，当代码到达password_reset网址时您会遇到另一个问题，因为它是从main_app引用的，您再次无法导入

Answer 2

尝试使用django-admin startproject创建新项目，并通过manage.py和wsgi.py复制所需的设置/副本。

某些版本发生了重大变化，即wsgi模块如何导入某些django内容。大多数项目都可以轻松重新创建，并且文件中有最新的django默认值。

这当然只是猜测，但值得一试。如果你正在使用virtualenv，你可能需要重新创建一些内容，当你的python升级/你移动了virtualenv。这样的东西有时会很烦人。

已解决！

Euh我想...

我添加以下几行：

from django.contrib.auth.views import login 
from django.contrib import auth

它的作品！
