DetailSerializer to have listserializer property - django

Question

I want to add json data from the listserializer to the DetailSerializer class. The serializer looks something like this:
serializer.py
class ListSerializer(serializers.ModelSerializer):
class Meta:
model = Fastest_laps
fields = '__all__'
class DetailSerializer(serializers.ModelSerializer):
listserializer = ListSerializer( read_only=True, many=True)
class Meta:
model = Driver
fields =
('place_of_birth','driver','listserializer','picture')
But i dont really see the data once i view it, i only see the detailserializer data( Driver model)
class Fastest_laps(models.Model):
driver_name = models.CharField(max_length=25, null=True)
grand_prix = models.CharField(max_length=15, blank=True)
car_model = models.CharField(max_length=50)
time_taken = models.CharField(blank=True, max_length=8)
def __str__(self):
return self.driver_name
class Driver(models.Model):
place_of_birth = models.CharField(max_length=25)
driver = models.ForeignKey(Fastest_laps,
db_column='driver_name')
picture = models.ImageField(blank=True, null=True)
def __str__(self):
return str(self.driver)
api.py
class FastLapsSet(ModelViewSet):
queryset = Fastest_laps.objects.all()
serializer_class = ListSerializer
class DriverSet(ModelViewSet):
queryset = Driver.objects.all()
serializer_class = DetailSerializer

Answer 1

you should rename your property as model name field:
class DetailSerializer(serializers.ModelSerializer):
driver = ListSerializer(read_only=True)
# ^^^
class Meta:
model = Driver
fields =
('place_of_birth','driver','driver','picture')
or add the source attribute:
class DetailSerializer(serializers.ModelSerializer):
listserializer = ListSerializer(source='driver', read_only=True)
#^^^^
class Meta:
model = Driver
fields =
('place_of_birth','driver','listserializer','picture')
