如何将URL插入Flash消息？ [英] How to insert URL into flash messages?

问题描述

我阅读了这个（1）和这个（2）但我希望有一个简单的方法要做到这一点......那就有效！ （（1）和（2））都不适用于我。

I read this (1) and this (2) but I'd like to have a simple method to do that... and that works! Both ( (1) and (2) ) does not works for me.

我想添加一个指向'root_path'的链接。

I want to add a link to the 'root_path'.

推荐答案

你需要做两件事：首先，构建一个带有链接的flash消息，正如你所期望的那样：

You need to do two things: First, construct a flash message with a link in it, as you'd expect:

flash[:notice] = "Settings updated! <a href=\"#{root_path}\">Go home</a>."

然后，在您的视图中，您需要将其作为原始内容回显。这会跳过Rails 3自动转义受污染的字符串，因此请确保您永远不会通过此闪存传递用户输入：

Then, in your view, you'll need to echo it as raw content. This skips Rails 3's automatic escaping of tainted strings, so be sure you never pass user input through this flash:

<%=raw flash[:notice] %>
