id field in django rest framework serializer

Question

I\'m using django rest framework and just creating a simple serializer like this:

class PackageSerializer(serializers.HyperlinkedModelSerializer):

    class         


        

Answer 1

According to the Django Rest Framework Documentation:

The default implicitly-generated id field is marked as read_only. This causes it to be removed on updates.

Thus, if you need the id field in an update method, you must not declare it as read-only but use a read-write field instead:

class PackageSerializer(serializers.ModelSerializer):
    id = serializers.IntegerField()
