ValueError：太多值无法解压Django [英] ValueError: Too many values to unpack Django

问题描述

所以我刚刚部署了我的第一个Django应用。

So I just got my first django app deployed.

我做了 syncdb 并创建了我的超级用户帐户

I did a syncdb and created my superuser account for the site.

现在，当我访问页面并按登录按钮时，出现此错误。我认为这与密码有关，但是我不确定。

Now when I access the page and press the login button I get this error. I think it has something to do with the password but I'm not sure.

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

我使用的是通用登录视图

I'm using the generic login view

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

Exception Type: ValueError at /accounts/login/
Exception Value: too many values to unpack

推荐答案

是的，密码有问题。

错误在于密码已加密并存储在数据库中。从追溯中的语句 algo，salt，hsh = enc_password.split（’$’）可以清楚地看到。加密的密码拆分返回三个以上的值。

The error is in the way the password has been encrypted and stored in the DB. It can be clearly seen from the statement algo, salt, hsh = enc_password.split('$') in the traceback. The encrypted password splitting returns more than 3 values.

因此，请查看密码加密方案及其相关内容。

So, please have look at the password encryption schemes and related.
