Customize serializer

[ccapeng]

I am looking at how to customize serializer

How do I have data from two join tables?

In the restframework, I can do like :

class BookSerializer(serializers.ModelSerializer):
    category_name = serializers.CharField(source='category.name', read_only=True)
    publisher_name = serializers.CharField(source='publisher.name', read_only=True)
    author_last_name = serializers.CharField(source='author.last_name', read_only=True)
    author_first_name = serializers.CharField(source='author.first_name', read_only=True)

    class Meta:
        model = Book
        fields = (
            'id', 
            'title', 
            'category', 
            'category_name', 
            'publisher', 
            'publisher_name', 
            'author', 
            'author_last_name', 
            'author_first_name'
        )

How should I do in grpc?

I almost got my django-grpc + react CRUD working.
