django-rest-framework how to make model serializer fields required

Question

I have a model that I\'m filling out step by step, it means I\'m making a form wizard.

Because of that most fields in this model are required but have null=Tru

You need to override the field specifically and add your own validator. You can read here for more detail http://www.django-rest-framework.org/api-guide/serializers/#specifying-fields-explicitly. This is the example code.

def required(value):
    if value is None:
        raise serializers.ValidationError('This field is required')

class GameRecord(serializers.ModelSerializer):
    score = IntegerField(validators=[required])

    class Meta:
        model = Game
