I need to add validation to the PlayerSerializer to check that, if a Player is added with an age below 13, the parent_approval value is True. If the Player isn't valid, I should throw a serializers.ValidationError with "Children under 13 require parental approval" as the error message.
This calls for object-level validation with the validate
method, correct? I'm not sure what I'm doing wrong.
from rest_framework import serializers
from . import models
class GameSerializer(serializers.ModelSerializer):
class Meta:
fields = ('id', 'name')
model = models.Game
class PlayerSerializer(serializers.ModelSerializer):
class Meta:
fields = ('id', 'name', 'age', 'parent_approval')
model = models.Player
def validate(self, data):
if data['age'] < 13 and not data['parental_approval']:
raise serializers.ValidationError(
'Children under 13 require parental approval')
return data
class ScoreSerializer(serializers.ModelSerializer):
game = serializers.HyperlinkedRelatedField(
read_only=True, view_name='apiv2:game-detail')
player = serializers.HyperlinkedRelatedField(
read_only=True, view_name='apiv2:player-detail')
class Meta:
fields = ('id', 'game', 'player', 'score')
model = models.Score

if data['age'] < 13 and not data['parental_approval']:
