Django User.set_密码导致密码无效

我正在尝试编写一个序列化程序（在Django REST框架中）来更新用户的帐户详细信息。下面是update（）方法：

当我以“password”、“confirm_password”和“old_password”作为字段对视图执行补丁请求时，它似乎已经工作了。然后，当我再次尝试登录该帐户时，它失败了（使用旧密码和新密码）。当我检查管理员设置并查看我试图编辑的用户时，我得到以下信息：

密码格式无效或哈希算法未知。

未存储原始密码，因此无法查看此用户的密码 密码，但您可以使用此表单更改密码

我相信User.set\u password（）应该自动处理散列等操作，那么我为什么会出现这个错误呢？

您从

self.validated\u data

中删除了

password

，而不是从传递给超类的

update

方法的

validated\u data

中删除了

。试试这个：

validated_data.pop("password") # remove self, just leave validated_data

return super(UserInfoSerializer, self).update(instance, validated_data)

如果有人对使用我的代码感兴趣，以下是最终的工作代码：

def update(self, instance, validated_data):
    ...
    if all([item in validated_data for item in ["password", "confirm_password", "old_password"]]):
        user = authenticate(username=instance.username, password=validated_data["old_password"])
        if user is not None and user == instance:
            if validated_data["password"] == validated_data["confirm_password"]:
                validate_password(validated_data["password"])
                instance.set_password(validated_data["password"])
                instance.save()  # change the password on the current instance object, otherwise changes will be overwritten
                login(self.context["request"], instance)  # without this line, the user is auto-logged out upon changing their password
            else:
                raise serializers.ValidationError({"confirm_password": "Passwords do not match"})
        else:
            raise serializers.ValidationError({"old_password": "Password incorrect"})

    if "password" in validated_data:
        validated_data.pop("password")

    return super(UserInfoSerializer, self).update(instance, validated_data)

def update(self, instance, validated_data):
    ...
    if all([item in validated_data for item in ["password", "confirm_password", "old_password"]]):
        user = authenticate(username=instance.username, password=validated_data["old_password"])
        if user is not None and user == instance:
            if validated_data["password"] == validated_data["confirm_password"]:
                validate_password(validated_data["password"])
                instance.set_password(validated_data["password"])
                instance.save()  # change the password on the current instance object, otherwise changes will be overwritten
                login(self.context["request"], instance)  # without this line, the user is auto-logged out upon changing their password
            else:
                raise serializers.ValidationError({"confirm_password": "Passwords do not match"})
        else:
            raise serializers.ValidationError({"old_password": "Password incorrect"})

    if "password" in validated_data:
        validated_data.pop("password")

    return super(UserInfoSerializer, self).update(instance, validated_data)
