问题描述

after_create 和 after_save 是否与每个功能相同?

Are after_create and after_save the same as per functionality?

我想在用户创建帐户后对其电子邮件进行操作.

I want to do an operation with the email of a user after its account creation.

我想在它保存在数据库中时做那个操作.

I want to do that operation when it is saved in the database.

哪个更适合使用:after_create 或 after_save?

which is preferable to use: after_create or after_save?

推荐答案

after_create 只工作一次 - 就在第一次创建记录之后.

after_create only works once - just after the record is first created.

after_save 每次保存对象时都有效 - 即使您在多年后才更新它

after_save works every time you save the object - even if you're just updating it many years later

因此，如果您只想执行此电子邮件操作一次(然后再也不执行)，请使用 after_create.

So if you want to do this email operation only just the once (and then never again) then use after_create.

如果你想每次保存对象时都这样做，那么在after_save

If you want to do it every time the object is saved, then do it in after_save
