Question

为所有网页呈现操作（即“新闻”）的正确方法是什么？我想要这样的东西：

application.html.erb

<!DOCTYPE html>
<html>
...
 <div class="side">
  <%= render :template => 'news/index' %> 
 </div>
 <div class="main">
  <%= yield %>
 </div>
...
</html>

和news_controller.rb

class NewsController < ApplicationController
  def index
   @news_previews = News.news_for_quick_preview
    render :layout => false 
  end
end

但是现在它没有用。 @news_previews =＆gt;零

Answer 1

在应用程序控制器中添加before_filter :load_news

before_filter :load_news 
def load_news
  @news_previews = News.news_for_quick_preview
end

在所有页面上渲染操作
