推荐答案

leelum1 和 aman kumar 的答案对我有很大帮助，因为我有同样的问题。我将添加一个有关如何使用他们的答案的特定示例。在下面的代码中，我尝试获取所有具有 category 属性的产品，并在 cat 变量上传递相同的字符串

Answers from leelum1 and aman kumar helped me a lot, since I had the same question. I would add a particular example of how I used their answers. In the code below I try to obtain all the products that have as category attribute the same string passed on the cat variable from the url.

class ListProductsView(generics.ListCreateAPIView):
    serializer_class = ProductSerializer
    def get_queryset(self):
        queryset = Product.objects.filter(category=self.kwargs['cat'])
        return queryset

这解决了我使用url中的变量过滤对象的问题。

That solved my problem of filtering objects by using variables from the url.
