python - How to serialize related models in Django Rest API? -

i have tried solutions. still cannot resolve it. here codes.

models.py

class car(models.model):     car_name = models.charfield(max_length=250)     car_description = models.charfield(max_length=250)       def __str__(self):         return self.car_name + ' - ' + str(self.pk)  class owners(models.model):     car = models.foreignkey(car, on_delete=models.cascade, default=0)     owner_name = models.charfield(max_length=250)     owner_desc = models.charfield(max_length=250)      def get_absolute_url(self):         return reverse('appname:index')      def __str__(self):         return self.owner_name + ' - ' +    self.owner_desc 

serializers.py

class ownersserializer(serializers.modelserializer):       class meta:         model = owners         fields = '__all__'   class carserializer(serializers.modelserializer):        owners = ownersserializer(many=true, read_only=true)     class meta:         model = car         fields = '__all__' 

views.py

class carlist(apiview):      def get(self, request):         cars = car.objects.all()         serializer = carserializer(cars, many=true)         return response(serializer.data)      def post(self):         pass     

i can't view 'owner' objects related object of 'car' class.

you need define related name on foreignkey create reverse reference.

class owners(models.model):      car = models.foreignkey(car, on_delete=models.cascade, default=0, related_name='owners')
