I have a question on this task. It is task #3 out of 3. I keep getting Bummer! GameSerializer has the wrong fields; PlayerSerializer has the wrong fields
from django.db.models import Avg
from rest_framework import serializers
from . import models
class GameSerializer(serializers.ModelSerializer):
average_score = serializers.SerializerMethodField()
class Meta:
fields = ('id', 'name', 'average_score')
model = models.Game
def get_average_score(self, obj):
average = obj.scores.aggregate(Avg('score')).get('score__avg')
if average is None:
return 0
return average
return round(average*2)/2
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['parent_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
