Got AttributeError when attempting to get a value for field `hotel` on serializer `ResidenceSerializ-CodePudding

class Hotel (models.Model):
name = models.CharField()
country = models.CharField()
city = models.CharField()
street = models.CharField() 


class Residence(models.Model):
hotel_id = models.ForeignKey(Hotel, on_delete=models.DO_NOTHING, related_name='hotel')
house_number = models.CharField()

I created two models Hotel and Residence and I want to join them together

serializers.py

class HotelSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
      model = Hotel
      fields = ['name', 'country', 'city', 'street']


class ResidenceSerializer(serializers.HyperlinkedModelSerializer):
   hotel = HotelSerializer()

   class Meta:
     model = Residence
     fields = ['house_number', 'hotel']

In the serializers.py, I wrote this code

 views.py

 class ResidenceViewSet(viewsets.ModelViewSet):
 serializer_class = ResidenceSerializer
 queryset = Residence.objects.all()

In the serializers.py, I wrote this code but when I try to run my code I get this error: Got AttributeError when attempting to get a value for field hotel on serializer ResidenceSerializer. The serializer field might be named incorrectly and not match any attribute or key on the Residence instance. Original exception text was: 'Residence' object has no attribute 'hotel'. Can anyone help me?

CodePudding user response：

can you do the following changes

class RegisterResidenceSerializer(serializers.HyperlinkedModelSerializer):
   complex_id = RegisterComplexSerializer()

   class Meta:
     model = Residence
     fields = ['house_number_extension_1', 'complex_id']
