Improperty在 django 中配置了自定义密码值管理器的问题

问：

我正在为 django 编写自定义密码验证器。但是我收到 InproperlyConfigured 错误 ->

配置不当 django.core.exceptions.ImproperlyConfigured：无法导入 NAME 中的模块：auth.validators.UppercaseValidator。检查您的AUTH_PASSWORD_VALIDATORS设置。

settings.py（路径：app/conf/settings/settings.py）。->

AUTH_PASSWORD_VALIDATORS = [
    {'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator'},
    {'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', 'OPTIONS': {'min_length': 12}},
    {'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator'},
    {'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator'},
    {'NAME': 'auth.validators.UppercaseValidator'},
]

validators.py（路径：app/auth/validators.py）。->

import re

from django.core.exceptions import ValidationError
from django.utils.translation import ugettext as _


class UppercaseValidator(object):
    def validate(self, password, user=None):
        if not re.findall('[A-Z]', password):
            raise ValidationError(
                _("The password must contain at least 1 uppercase letter, A-Z."),
                code='password_no_upper',
            )

    def get_help_text(self):
        return _("Your password must contain at least 1 uppercase letter, A-Z.")

我开始有点疯狂，因为我看不出问题出在哪里 Priz帮帮我
