Django 1.6 到 1.11 Admin.py 迁移

Question

我正在尝试将旧的 Django 1.6 admin.py 代码移植到 Django 1.11 中，无论出于何种原因，它在 1.11 上都不起作用。我将下面的代码发送给您，因此你们中的一些人可能会给我一些关于旧代码可能无法在 Django 1.11 上运行的区域的观点。提前感谢您的任何提示。

Answer 1

结果很简单。在我上面的代码中，有一些方法，比如...

def 查询集（自我，请求）：

... 这在 Django 1.6 中很好。但是 Django 1.11 的正确覆盖应该是...

def get_queryset(self, request):
