Question

我需要在闪存通知中添加换行符。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＆amp; Rails 4.0.10

Answer 1

在编程中总是有一种肮脏的方法。在这里你可以在flash中创建多线阵列。

     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

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

这肯定会奏效。

但最好的办法就是这个

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

如果这也不起作用，那就试试另一种方式

在控制器集

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

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

Answer 2

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

Answer 3

添加<br/>标记而不进行插值，它将起作用。

"We will notify you when we go LIVE! <br/> Meantime, complete this quick survey so we can get to know your interest."
