Fill all three blanks to write a serializer that validates a book's title length and includes an author field.

Django

from rest_framework import serializers

class BookSerializer(serializers.Serializer):
    title = serializers.[1](max_length=100)
    author = serializers.[2](max_length=50)

    def validate_title(self, value):
        if len(value) < [3]:
            raise serializers.ValidationError("Title too short")
        return value

Setting minimum length as a string instead of number

Both title and author are text fields, so use CharField. The minimum title length is set to 5.
