Django 1.6 到 1.11 Admin.py 迁移

Posted 2023-02-24

【中文标题】Django 1.6 到 1.11 Admin.py 迁移

【英文标题】：Django 1.6 to 1.11 Admin.py migration

【发布时间】：2018-04-13 16:46:37

【问题描述】：

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。

【问题讨论】：

请不要把代码扔给我们检查。如果您有多个问题，请将您的代码分成几个问题，并告诉我们您尝试了什么、确切的错误消息是什么、抛出它的行等。

立即升级 5 个主要版本永远不会奏效，您应该逐步升级。

无论如何，您需要告诉我们您遇到的实际问题以及遇到的错误。

第一个在 1.6 中有效而在 1.11 中无效的东西就在顶部。方法 def queryset(self, request): in class FilteredUserAdmin(admin.ModelAdmin): 在 1.11 中没有被调用。

【参考方案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):
