Django Rest Framework Model Id Field In Nested Relationship Serializer

I'm usign Django Rest Framework where I have the following two serializers: class ServiceSerializer(serializers.ModelSerializer): id = serializers.ReadOnlyField() class M

Solution 1:

Ok - I think I found the answer after ... carefully reading the docs :)

So according to the docs the id field could be set to a ModelField like this:

id = serializers.ModelField(model_field=ServiceType()._meta.get_field('id'))

Indeed, after adding this line the id field is present in validated_data :)

Solution 2:

The accepted answer works but is unnecessarily complicated. You can just change the ID field to not be readonly. E.g. something like this will do:

id = serializers.IntegerField(required=False)

Solution 3:

You have set id as a ReadOnlyField. That's why id does not appear in validated data. Just remove this line:

id = serializers.ReadOnlyField()

Solution 4:

The more straightforward option:

id = serializers.IntegerField(write_only=False)
