轨道3：Ajax的更新视图部分 [英] Rails 3: Ajax-updating a view with a partial

问题描述

我在做什么毛病下面的Ajax请求......？

what am I doing wrong with the following Ajax request...?

<%= link_to 'Business Analysis', it_business_analysis_path, :remote => true %>

的路线：

match 'it/business_analysis' => 'informationtechnology#business_analysis', :as => :it_business_analysis

控制器：

class InformationtechnologyController < ApplicationController  
  def business_analysis

    render :update do |page|
      page.replace_html 'page_content', :partial => 'business_analysis'
    end

  end
end

的看法：

<div id="page_content">
</div>

的部分被称为：

_business_analysis.html.erb

的错误：

Action Controller: Exception caught

<h1>Template is missing</h1>
<p>Missing template informationtechnology/update, application/update with {:formats=&gt;[:js, &quot;application/ecmascript&quot;, &quot;application/x-ecmascript&quot;, :html, :text, :js, :css, :ics, :csv, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json], :handlers=&gt;[:builder, :coffee, :erb], :locale=&gt;[:en, :en]}. Searched in: * &quot;/home/<user_name>/Websites/<project_name>/app/views&quot;

看来Rails是寻找一个名为更新的看法 - 为什么？如何解决这个问题

It seems Rails is looking for a view called "update" - why and how do I fix this?

非常感谢！ 汤姆

推荐答案

好了，任何人具有类似isssue，我找到了解决办法：

Ok, for anybody having a similar isssue, I found the solution:

的问题是，在Rails3，原型置换与jQuery。为此以下code是不再有效：

The problem is that, in Rails3, Prototype was replaced with jQuery. Therefor the following code is no longer valid:

render :update do |page|
  page.replace_html 'page_content', :partial => 'business_analysis'
end

下面的2个链接会解释如何处理jQuery的细节：
