通过重定向使闪存哈希持久化 [英] getting the flash hash to persist through redirects

问题描述

我的基本用例是做一些处理，设置flash[:notice]，然后重定向到一个新页面.据我所知，重定向重置了 flash 标签(如果我错了，请纠正我).有没有办法获得坚持?使用会话不是一种选择，我已经使用 cookie 解决了这个问题，但我认为必须有更好的方法.

My basic use case is do some processing, set flash[:notice], and then redirect to a new page. From what I can tell, redirects reset the flash tag (please correct me if I'm wrong). Is there a way to gain persistence? Using sessions isn't an option, and I have hacked around the problem using cookies, but I think there's got to be a better way.

推荐答案

Flash 散列仅在一次重定向或呈现中持续存在.所以你应该可以使用默认设置.

The flash hash persists for exactly one redirect or render. So you should be fine with the default settings.

如果你需要为另一个请求/重定向保留 flash 哈希，你可以调用 flash.keep.

If you need to keep the flash hash for another request/redirect, you can call flash.keep.

flash.keep # keep the entire flash hash around for an extra request.
flash.keep(:notice) # keep just flash[:notice] for an extra request.
