Ruby on Rails.如何只显示一次记录? [英] Ruby on Rails. How to show record only once?

问题描述

我想知道如何仅在创建后才显示记录.所以我只想展示一次.

I want to know how to show a record only exactly after it was created. So i want to show it only once.

看看吧.我有一个名为 Claim 的模型.用户创建新声明(用户是匿名的).我只想在用户创建它后才显示此声明，而不再显示.我该怎么做?

Just see. I have model called Claim. User creates new Claim (user is anonymous). I want to show this Claim only ofter user creates it and never again. How can I do it?

我认为我可以使用 flash hash，但我认为从用户数据创建符号还不够安全.

I think that I can use flash hash, but i think it is not enough secure to create symbols from user data.

推荐答案

您可以在模型上设置一个 viewed 属性，并在 show 操作中将其设置为 true.如果 viewed 为真，则跳过渲染视图.

You could have a viewed attribute on your model that you set to true in the show action. If viewed is true then skip rendering the view.

unless thingy.viewed 
  thingy.viewed = true
  thingy.save

  render like normal...
end
