ValueError:解压缩Django的值过多

Question

所以我刚刚部署了我的第一个django应用程序.

我做了一个syncdb并为该网站创建了我的超级用户帐户.

现在,当我访问该页面并按下登录按钮时,我收到此错误.我认为它与密码有关,但我不确定.

ValueError at /accounts/login/
too many values to unpack

我正在使用通用登录视图

(r'^accounts/login/$', login, {'template_name': 'authentication/login.html'}),

以下是回溯

Answer 1

刚遇到同样的问题.

似乎在我的情况下,当创建密码时,该网站使用Django 1.4运行(由于PYTHONPATH混淆).

当我尝试使用1.3.1登录运行网站时出现此错误.然后我注意到Django版本,切换到1.4并且登录再次开始工作.

似乎密码算法在1.4中已更改:

https://docs.djangoproject.com/en/dev/releases/1.4-beta-1/#improved-password-hashing

如果您使用的是Django 1.4 alpha,那么密码可能也会被破坏(请阅读警告).

Answer 2

最简单的解决方法是从命令行重置密码.

./manage.py changepassword <user>

Answer 3

您可以在shell中重置密码.

from django.contrib.auth.models import User
u = User.objects.get(username="myuser")
u.set_password("mypassword")
u.save()

当我们从1.4.X降级到测试@ h3详述的旧部署时会发生这种情况.

Answer 4

是的,密码有问题.

该错误与密码加密并存储在数据库中的方式有​​关.从algo, salt, hsh = enc_password.split('$')追溯中的陈述可以清楚地看出.加密的密码拆分返回3个以上的值.

那么,请看一下密码加密方案和相关的.
