How do I get the name of the container to show instead of the id?-CodePudding

So I am trying to figure out how to display the ForeignKey name in the view I have thought about using map method and get the object from the ID and getting the name from said ID, but that doesn't seem to work. I could be doing it wrong but I am not quite sure.

JSON Response

[
    {
        "id": 3,
        "name": "Coke",
        "description": "Cocaine Drink",
        "container": 3
    },
    {
        "id": 4,
        "name": "Another One",
        "description": "Dj Khaled Drink",
        "container": 3
    },
    {
        "id": 5,
        "name": "Testy",
        "description": "Westy",
        "container": 4
    }
]

View

class ListDrinks(APIView):

    authentication_classes = []
    permission_classes = []
    
    def get(self, request, format=None):
        drinks = Drink.objects.all()
        serializer = DrinkSerializer(map(DrinksId, drinks), many=True)
        return Response(serializer.data)

    def post(self, request, format=None):
        serializer = DrinkSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Models

class Container(models.Model):
    name = models.CharField(max_length=200)

    def __str__(self):
        return self.name


class Drink(models.Model):
    name = models.CharField(max_length=200)
    description = models.CharField(max_length=500)
    container = models.ForeignKey(
        Container, on_delete=models.CASCADE, null=True)

    def __str__(self):
        return self.name

Serializers


class DrinkSerializer(serializers.ModelSerializer):
    class Meta:
        model = Drink
        fields = ['id', 'name', 'description', 'container']


class ContainerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Container
        fields = ['id', 'name']

CodePudding user response：

First of all you can use ListCreateAPIView for your view check it later.

And for your question check this out and update the DrinkSerializer to this

class DrinkSerializer(serializers.ModelSerializer):
    container = serializers.CharField(source="container.name", read_only=True)
    class Meta:
        model = Drink
        fields = ['id', 'name', 'description', 'container']

And you can do this, I think is better.

    ...
    def get(self, request, format=None):
        serializer = DrinkSerializer(Drink.objects.all(), many=True)
        ...
