django 管理员覆盖 delete_model 不使用批量删除

Question

我想为特定模型实例禁用删除

我在 ModelAdmin 中覆盖了 delete_model 如下：

def delete_model(self, request, client):
    if client.schema_name == 'public':
        messages.set_level(request, messages.ERROR)
        messages.error(request, 'Suppression interdite pour la racine')
    else:
        super().delete_model(request, client)

当我在更改视图上单击删除按钮时有效

但不能使用批量删除，因为实例会在没有阻止的情况下被删除

我该如何解决这个问题？我还意识到 delete_model 没有被批量删除调用，这有点奇怪。

作为批量删除管理员操作documentation 已经警告您

The “delete selected objects” action uses QuerySet.delete() for efficiency reasons, which has an important caveat: your model’s delete() method will not be called.

If you wish to override this behavior, you can override ModelAdmin.delete_queryset() or write a custom action which does deletion in your preferred manner – for example, by calling Model.delete() for each of the selected items.

For more background on bulk deletion, see the documentation on object deletion.
