DRF: How to get object in ModelSerializer.validate()

Question

I need to get the current object in ModelSerializer.validate() when it's being updated(not created)

Currently, I'm using self._args[0]

class UserInfoSerializer(serializers.ModelSerializer):

    class Meta:
        model = UserInfo
        fields = ('id', 'Username')

    def validate(self, data):
        current_user = self._args[0]  # <--

It's something like self.get_object() in ViewSet

I wonder if there is a better way to get what I want, any idea? thanks

You can use the .instance attribute

Example:

class UserInfoSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserInfo
        fields = ('id', 'Username')

    def validate(self, data):
        


# initialization
s = UserInfoSerializer(data={"foo": "bar"}, )
