我正在使用Django 1.5。我有以下型号:

class User(AbstractBaseUser):
    #id = models.IntegerField(primary_key=True)
    #identifier = models.CharField(max_length=40, unique=True, db_index=True)
    username = models.CharField(max_length=90, unique=True, db_index=True)
    create_time = models.DateTimeField(null=True, blank=True)
    update_time = models.DateTimeField(null=True, blank=True)
    email = models.CharField(max_length=225)
    password = models.CharField(max_length=120)
    external = models.IntegerField(null=True, blank=True)
    deleted = models.IntegerField(null=True, blank=True)
    purged = models.IntegerField(null=True, blank=True)
    form_values_id = models.IntegerField(null=True, blank=True)
    disk_usage = models.DecimalField(null=True, max_digits=16, decimal_places=0, blank=True)
    objects = UserManager()
    USERNAME_FIELD = 'email'
    class Meta:
        db_table = u'galaxy_user'

运行./manage.py syncdb时出现此错误:

FieldError: Local field 'password' in class 'User' clashes with field of similar name from base class 'AbstractBaseUser'

我尝试从模型中删除密码字段,但即使从模型中删除了密码字段,也没有进行身份验证。 我正在使用我的自定义Django身份验证:

class AuthBackend:
    def authenticate(self, username=None, password=None):
        if '@' in username:
            kwargs = {'email': username}
        else:
            kwargs = {'username': username}
        try:
            user = User.objects.get(**kwargs)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

与普通的python继承不同,Django中不允许使用字段名“hide”

只需使用抽象用户提供的密码字段,并在保存方法或表单/ api中进行任何自定义保存/检查
