What I would like to happen is every single time a new file is uploaded, user.space_used is updated.
我希望发生的是每次上传一个新文件时，用户。space_used更新。
But that doesn't happen right now. In order to get an update, I have to manually run user.update_space at the console to update a specific user, or use an array to cycle through all the users and update it like that.
但这种情况现在还没有发生。为了获得更新，我必须手动运行用户。控制台的update_space用于更新特定的用户，或者使用一个数组循环遍历所有的用户并像这样更新它。
How do I get it to do it at the right time - also, it would be nice if I could verify that the space_used column on the User model has the total sum of the filesizes of all the files uploaded for that user on the Upload model.
如何让它在正确的时间完成它呢?另外，如果我能验证用户模型上的space_used列拥有上传模型上所有用户上传的文件的总和，那就太好了。
My user model looks like this:
我的用户模型是这样的:

Thanks.
谢谢。
Edit1: Btw, I am using paperclip to manage the uploads.
顺便说一句，我正在使用paperclip管理上传。
Edit2: In the Upload.rb model, I changed the before_save to the after_post_process callback for paperclip and it still doesn't work.
Edit2:在上传。rb模型，我将before_save更改为paperclip的after_post_process回调，它仍然不起作用。

Seems like Paperclip's after_post_process callback would be what you want.
似乎Paperclip的after_post_process回调是您想要的。
