Question

我有如下的扩展用户模型..

class User(AbstractEmailUser):

    first_name = models.CharField(verbose_name=_('First name'),max_length=128)
    last_name = models.CharField(verbose_name=_('Last name'), max_length=128)
    avatar = StdImageField(upload_to='user_avatars/', null=True, blank=True, variations={
        'thumbnail': (settings.AVATAR_THUMBNAIL_WIDTH, settings.AVATAR_THUMBNAIL_HEIGHT, True)
    })
    user_name = models.CharField(null=True,blank=True,verbose_name=_('User id'), max_length=128)


    def get_short_name(self):
        return self.last_name

    def get_full_name(self):
        return "%s %s" % (self.first_name, self.last_name)

    def __unicode__(self):
        return self.email

    def get_thumbnail_url(self):
        return self.avatar.thumbnail.url if self.avatar else None

我想在扩展用户模型中使用电子邮件字段和admin by user_name字段验证除admin之外的所有用户.....我正在使用django 1.9

有没有默认方法可以做到这一点......

因此，您应该创建自定义身份验证后端。身份验证之前的用户是匿名的，因此我们无法判断他是否是管理员。我认为你可以这样做的方法是使用用户名或电子邮件验证用户，如果他们是管理员用户验证他们使用的任何东西（用户名或电子邮件），但普通用户应该使用电子邮件，如果不是，则返回None。

WebClient cl = new WebClient();
NameValueCollection nvm = new NameValueCollection();

nvm["name"] = data.Name;
nvm["description"] = data.Description;
nvm["file"] = // File.OpenRead(data.FilePath) ? or how send file content ?

cl.UploadValues("https://database.org/upload.php", "POST", nvm);

和from django.contrib.auth.backends import ModelBackend from django.contrib.auth import get_user_model from django.core.validators import validate_email from django.contrib.auth.hashers import check_password class MyAuthenticationBackend(ModelBackend): """ Authenticate All users if Email is used but just the admin if username is used """ def authenticate(self, request, username=None, password=None): try: validate_email(username) valid_email = True kwargs = {'email': username} except: valid_email = False kwargs = {'username': username} try: user = get_user_model().objects.get(**kwargs) except get_user_model().DoesNotExist: print("User model does not exist!") return None if valid_email and user.check_password(password): print("Email used. Authenticate all users") return user elif not valid_email and user.check_password(password) and user.is_admin: print("Username used. Authenticate admin users") return user else: print("something else return None") return None def get_user(self, user_id): try: return get_user_model().objects.get(pk=user_id) except get_user_model().DoesNotExist: return None档案

settings.py

用于身份验证的字段应该具有唯一设置为True，而空白和null应该为False。

AUTHENTICATION_BACKENDS = [
'app.admin.MyAuthenticationBackend',
]
