Exclude a field from django rest framework serializer

Question

In the following serializer, I have a nested serializer [ ContainerSerializer ] field and I want to exclude a field from (container) ContainerSerializer but I don't want any change in ContainerSerializer . How can I do that?

class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = ContainerSerializer()
    class Meta:
        model = BLcontainer

Answer 1

Create another serializer say BLContainerSerializer and exclude fields there. Then use this in your BLcontainerMergedSerializer . Hope this helps.

class BLContainerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Container
        exclude = ('field1', )


class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = BLContainerSerializer()
    class Meta:
        model = BLcontainer

Answer 2

There is a fields meta property:

class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = ContainerSerializer()
    class Meta:
        model = BLcontainer
        fields = ('field1', 'field2')
