Django __init__() 得到了一个意外的关键字参数“用户”

Question

我正在尝试使用默认的 django 库构建密码重置系统。问题是在尝试进入要更改它的站点（PasswordChangeConfirm）后出现此错误跟踪。

Internal Server Error: /reset/confirm/MQ/atg5tq-aa6bcab1c34d1228cdd1970aaaa45252/

                </form>

我正在使用小部件调整来呈现表单，但我想这不是问题，因为对于其他事情，它可以工作。

你的password_reset_view继承自PasswordResetConfirmView [Django docs]，这个视图通常使用SetPasswordForm的形式，它以用户为参数（因为它需要设置用户密码），问题是你的形式CaptchaPasswordResetForm继承自PasswordResetForm（不正确），因此您会收到错误消息。您应该更新您的表单类以正确继承：

from django.contrib.auth.forms import SetPasswordForm


class CaptchaPasswordResetForm(SetPasswordForm):
    ...
