Django Rest 框架：我应该使用 URL Slugs 还是查询参数来列出特定类别的项目？

Question

Right now I have a viewset that allows me to:

1. List all the products on: www.example.com/api/products
2. Retrieve the detail information of one product on: www.example.com/api/products/5

The problem is that in the mobile application the products will only be visible when you are inside a category and subcategory.

The product model looks something like this:

class Product(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()
    image = models.CharField(max_length=255)
    category = models.ForeignKey(ProductCategory, related_name='products', on_delete=models.CASCADE)
    subcategory = models.ForeignKey(ProductSubcategory, related_name='products', on_delete=models.CASCADE)

And the product Viewset looks like this:

class RoutineViewSet(mixins.ListModelMixin,
                     mixins.RetrieveModelMixin,
                     viewsets.GenericViewSet):

    queryset = models.Product.objects.all()   

    def get_serializer_class(self):
        if self.action == 'list':
            return serializers.ProductListSerializer
        else:
            return serializers.ProductDetailSerializer

Should I be using a slug or ID in the endpoint to get the items?

www.example.com/api/products/category/food/subcategory/snacks
www.example.com/api/products/category/2/subcategory/3

Or should I be using query parameters?

www.example.com/api/products/?category=2,subcategory=3

My instinct tells me that the easiest way would be to use query parameters and overwrite the "get_queryset" method to get different products depending on the query parameters. But I'm not sure if that is the standard way of doing something like this.

Thanks

you should define Sub Category @action in your View with detail=True
