django-rest-framework 如何处理多个 URL 参数？

Question

如何使用具有多个 URL 参数的通用视图？喜欢

GET /author/{author_id}/book/{book_id}

class Book(generics.RetrieveAPIView):

    queryset = Book.objects.all()
    serializer_class = BookSerializer
    lookup_field = 'book_id'
    lookup_url_kwarg = 'book_id'

    # lookup_field = 'author_id' for author
    # lookup_url_kwarg = 'author_id'

Answer 1

您需要在 URL 结构中使用命名组，并可能覆盖get()视图的方法。
