Setting which functions as a post. It has the variables: Title:string Description:text, Photo:image and Paragraph:text.
设置哪个功能作为帖子。它有变量：标题：字符串描述：文本，照片：图像和段落：文本。
I have another controller which controls my Home, About, News and contact.
On my Home, I'm trying to access the title of the setting with the id 3. I can't figure it out. Do i need to define the controls for the settings in the page controller as well? How can I access it?.
我有另一个控制器来控制我的家，关于，新闻和联系。在我家，我正在尝试访问ID为3的设置标题。我无法弄明白。我是否还需要为页面控制器中的设置定义控件？我该如何访问它？
Here is my code at the Home,

<% @setting.(id[3]) do |setting| %>
<h2><%= setting.title %></h2>
<% end %>
Error: Undified local varible or method 'id' for #<#
错误：＃<＃的Undified local varible或method'id'

If you want to display single record then there is no need to have loop, so you can try this.
如果你想显示单个记录，那么就不需要循环，所以你可以试试这个。
<% setting = Setting.find(3) %>
<h2><%= setting.title %></h2>
