You are having the ,
after the name of BDetail
model in BDetailSerializer
serializer. Remove that and your code will work.
Suggestion: Inherit serializers.ModelSerializer
in your BDetailSerializer
serializer instead of serializers.HyperlinkedModelSerializer
i.e. :
class BDetailSerializer(serializers.ModelSerializer):
class Meta:
model = BDetail
fields = ('lat', 'lng')
