显示快闪消息的最佳实践方法 [英] Best practice method of displaying flash messages

问题描述

我想知道显示 Flash 消息的最佳做法是什么.我见过的两种主要方法是使用类似这种脚手架生成的代码

<%= notice %>

或将这样的代码放在您的应用程序标题中.

<% if !flash.empty?％＞<div id="闪存"><% flash.keys.each do |k|％＞<div class="<%= k %>"><%=闪光[k]%>

<%结束%>

<%结束%>

在我看来，第一种方法增加了更多的灵活性，而后者提高了代码的可读性并消除了冗余.有没有大多数 Rails 开发人员更喜欢的方法?作为一个附带问题，脚手架如何实施通知?它只是访问闪存哈希的助手吗?当您可以直接使用闪存哈希时，为什么还要麻烦使用助手?谢谢

解决方案

我是这样做的:

<% flash.each do |key, value|％＞<%= content_tag :div, value, class: "flash #{key}" %><%结束%>

I'm wondering what's the best practice for displaying flash messages. The two main ways I've seen are using something like this scaffold generated code

<p id="notice"><%= notice %></p>

or placing code like this in your application header.

<% if !flash.empty? %>
    <div id="flash"> 
        <% flash.keys.each do |k| %> 
            <div class="<%= k %>">
                <%= flash[k] %>
            </div>  
        <% end %>   
    </div>
<% end %>

It appears to me that the first method adds more flexibility while the latter improves code readability and eliminates redundancy. Is there a method most rails developers prefer? As a side question how does scaffolding implement notice? Is it just a helper that accesses the flash hash? Why go through the trouble of using the helper when you can directly use the flash hash? Thanks

解决方案

I'm doing it this way:

<% flash.each do |key, value| %>
  <%= content_tag :div, value, class: "flash #{key}" %>
<% end %>
