Question

我正在尝试将旧的Django 1.6 admin.py代码移植到Django 1.11中，无论出于什么原因，它都无法在1.11上运行。我发送给你下面的代码，所以你们中的一些人可能会给我一些旧代码的区域，这些区域可能不适用于Django 1.11。提前感谢任何暗示。

Answer 1

事实证明这很简单。在我上面的代码中，有一些方法，比如......

def queryset（self，request）：

......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）：

Django 1.6到1.11 Admin.py迁移
