如何定位这个问题？

Answer 1

发生了什么...

我不知道。值得注意的是，url 应该在 django/contrib/auth/admin 的 User Auth ModelAdmin 中调用一个名为 user_change_password 的方法。它具有以下签名：

def user_change_password(self, request, id, form_url=""):

这就是引发错误的原因，因为不知何故 extra_context 被传递给它。

还有一种方法可以让您更改登录用户的密码，它接受 extra_context kwarg。我最好的猜测是其中一个应用程序覆盖了标准身份验证 ModelAdmin 并且做得不太正确。当然，新的 django 3.0.7 项目一切正常。

How can I localize this problem?

我会删除您所有的附加应用程序。希望这能解决问题。如果没有，那么这将变得更加有趣。但如果确实如此，我会把它们一个一个地添加回来，直到它坏掉，然后你就会找出是哪个额外的应用程序坏了东西。

maybe you even can help me cope with it.

如果您只想更改密码，我可以想到一些您可以做的事情。您可以通过 shell:

更改用户详细信息

python manage.py shell

然后，您可以通过以下方式更改密码：

from auth.models import User
user = User.objects.get(id=1)  # Or whatever user you want
user.set_password('my_new_password')
user.save()

这应该可以解决问题。更简单的是，有一个管理命令可以执行此操作（但为此您需要知道当前密码）。您可以简单地 运行:

manage.py changepassword *username* 

Answer 2

我有这个问题（虽然在 Django 2.2 中）。它是在我听取了 adding extra_context to every admin page. This seems harmless, but breaks the "change password" form. In the end I deleted the 'extra_context' changes to urls.py and added the extra_context ONLY to the admin forms I needed using the ModelAdmin add_view and change_view methods.

上另一个 Stack Overflow post 的建议后开始的

# New Layer Form
def add_view(self, request, form_url='', extra_context={}):
    extra_context['CATALOG_TECHNOLOGY'] = settings.CATALOG_TECHNOLOGY
    return super(LayerAdmin, self).add_view(request, form_url, extra_context)

# Edit Layer Form
def change_view(self, request, object_id, extra_context={}):
    extra_context['CATALOG_TECHNOLOGY'] = settings.CATALOG_TECHNOLOGY
    return super(LayerAdmin, self).change_view(request, object_id, extra_context=extra_context)

以下是完整上下文的提交：

• 中断提交
  • urls.py
• 修复提交
  • urls.py
  • admin.py
