Friendly_id 和真实 ID [英] friendly_id and real id

问题描述

有没有办法从使用friendly_id修改的模型中获取真正的id列?

Is there any way to get the real id column from a model that is modified with friendly_id?

出于性能原因，我不想对其进行另一个数据库查询.

I don`t want to make another db query for it, in performance reasons.

推荐答案

从广义上讲，friendly_id 修改了 to_param 和 find 方法.接下来应该工作:

Broadly speaking friendly_id modifies to_param and find methods. Next should work:

@affiche = Affiche.find(params[:id]) # params[:id] is a slug
@id = @affiche.id
