Listing objects field instead of Object in Django Rest Framework-CodePudding

I've got a model

class Like(models.Model):
    product = models.ForeignKey('ProductInStore', on_delete=models.PROTECT)
    user = models.ForeignKey('users.CustomUser', on_delete=models.PROTECT)

    class Meta:
        unique_together = ('product', 'user',)

and a serializer

class LikeSerializer(serializers.ModelSerializer):
    user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault())
    product = serializers.PrimaryKeyRelatedField(read_only=True)

    class Meta:
        model = Like
        fields = ('user', 'product',)

class UserLikedProductsApiList(generics.ListAPIView):
    queryset = Like.objects.all()
    serializer_class = LikeSerializer

And so if someone likes a product, adds it to favourites, it creates an Like object in database. And i want to create an endpoint users/me/likedProducts so that i can list all the products that self.user.request has liked. Meaning all the Like instances but instead of Like instances i want to show only Like.product instances. Lets say a person x has liked 4 items, and i want to show only 4 items in that list. Do you have any idea how to get around that in Django Rest Framework?

CodePudding user response：

you can change the queryset from like model to ProductInStore model the query would look like this: ProductInStore.objects.filter(id__in=Like.objects.filter(user=self.request.user).values_list('product',flat_true)) and you can use the default product serializer
