How can I customize Django ORM serializers?

You can customize Django ORM serializers by overriding the to_representation and create methods in your serializer class.

Can you give me an example of overriding the to_representation method?

Sure! Here's a simple example:

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

    def to_representation(self, instance):
        representation = super().to_representation(instance)
        representation['custom_field'] = 'Custom Value'
        return representation

What about customizing the create method?

To customize the create method, you can do something like this:

def create(self, validated_data):
    instance = MyModel(**validated_data)
    instance.custom_field = 'Custom Value'
    instance.save()
    return instance

Thanks! How do I handle validation errors in serializers?

You can handle validation errors by overriding the validate method in your serializer. You can raise serializers.ValidationError for any invalid data.
