Question

With django-rest-framework 3.0 and having these simple models:

class Book(models.Model):
    title = models.CharField(max_length=50)


class         


        

Answer 1

You can simply use drf-writable-nested. It automatically make your nested serializers writable and updatable.

in you serializers.py:

from drf_writable_nested import WritableNestedModelSerializer

class RequestSerializer(WritableNestedModelSerializer):
    book_id = serializers.IntegerField()
    page = PageSerializer(many=True)


class PageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Page

And that's it!

Also the library supports using only one of the create and update logics if you don't need both.
