在 Flash 通知 Rails 控制器中添加换行符

Question

我需要在 Flash 通知中添加换行符。到目前为止我有这个

flash[:success] = "We will notify you when we go LIVE! #{<br />} Meantime, complete this quick survey so we can get to know your interest.

但这是不正确的。有谁知道如何在控制器中正确执行此操作？

我正在使用 ruby​​ 2.2.1p85 和 Rails 4.0.10

在编程中总是有一种肮脏的方式来做事。在这里您可以在闪存内创建多行阵列。

     flash[:success] = []
     flash[:success] = flash[:success] << "We will notify you when we go LIVE! "
     flash[:success] = flash[:success] << "Meantime, complete this quick survey so we can get to know your interest."

并像这样显示它

<% flash.each do |key, value| %>
  <% value.each do |text| %>
    <%= content_tag :div, text %>
  <% end %>
<% end %>   

这肯定会起作用。

但最好的方法是这样做

flash[:success] = "We will notify you when we go LIVE! <br> Meantime, complete this quick survey so we can get to know your interest.".html_safe

如果这也不起作用，请尝试其他方法

在控制器组中

flash[:success] = "We will notify you when we go LIVE! <br> Meantime, complete this quick survey so we can get to know your interest."  

并在视图中显示类似

 <% flash.each do | value| %>
    <%= content_tag :div, value.html_safe %>
 <% end %>
