模板渲染期间Django django.contrib.auth.views.password_reset_confirm错误

Question

I am implementing a user password reset using django views and I am getting some error with django.contrib.auth.views.password_reset_confirm

The link to reset the password comes through e-mail :

MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 7bit
Subject: Password reset on 127.0.0.1:8000
From: webmaster@localhost
To: progpyftk@yahoo.com
Date: Thu, 06 Oct 2016 19:01:30 -0000
Message-ID: <20161006190130.10100.76186@PEAMV57.exprogroup.local>


You're receiving this email because you requested a password reset for your user
 account at 127.0.0.1:8000.

Please go to the following page and choose a new password:

http://127.0.0.1:8000/account/password-reset/confirm/Mw/4fx-63795155cddbbad87a79
/

Your username, in case you've forgotten: Gileno

When I follow the link I got the following error:

   return get_password_validators(settings.AUTH_PASSWORD_VALIDATORS)

It looks like you have an invalid AUTH_PASSWORD_VALIDATORS setting. It should be a list of dictionaries. The error message suggests you have a list of strings instead.

The example given in the docs is:

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
        'OPTIONS': {
            'min_length': 9,
        }
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]
