Rails 3中的多层嵌套布局 [英] Multiple Level Nested Layout in Rails 3

问题描述

我有一个带有全局应用程序布局文件application.html.haml的应用程序.然后，我有多个控制器堆栈":用于我们的主站点，我们的管理门户和我们的业务站点.对于每个控制器，控制器都在模块内，并且都从相同的BaseController继承.每个堆栈都有其自己的布局文件.在堆栈中，某些控制器也具有布局文件.

I have an application with a global application layout file application.html.haml. I then have multiple "controller stacks": for our main site, our admin portal, and our business site. For each of these, controllers are within a module and all inherit from the same BaseController. Each stack has it's own layout file. Within the stack, some controllers have layout files as well.

我希望所有视图(除非另行指定)都可以在多层嵌套布局内渲染:应用程序，堆栈"，控制器".

I would like all views (unless otherwise specified) to render inside multiple levels of nested layouts : application, "stack", "controller".

例如，对于Site::BlogController#show动作，我希望使用Rails进行渲染:

For example, for the Site::BlogController#show action, I'd like rails to render:

/site/blog/show.html.haml内/layouts/site/blog.html.haml内/layouts/site.html.haml内/layouts/application.html.haml

我很难理解如何将/layouts/site.html.haml插入堆栈.看来，rails会自动将动作呈现在应用程序布局内的控制器布局内，但是，我看不到如何将布局插入"到渲染堆栈中.

I am having difficulty understanding how to insert /layouts/site.html.haml into the stack. It appears as though automatically, rails will render the action inside the controller layout inside the application layout, however, I can't see how to "insert" layouts into the render stack.

非常感谢您的帮助，但是，我已经阅读了所有Rails指南，但均无济于事，因此，链接到

Any help is greatly appreciated, however, I have read all the rails guides to no avail, so a link to http://guides.rubyonrails.org/layouts_and_rendering.html#using-nested-layouts will not really be helpful.

推荐答案

我重新阅读了我发布的链接( http://guides.rubyonrails.org/layouts_and_rendering.html#using-nested-layouts )，并意识到我错过了一个关键细节.

I reread the link i posted ( http://guides.rubyonrails.org/layouts_and_rendering.html#using-nested-layouts ) and realized I missed a key detail.

<%= render :file => 'layouts/application' %>

所以，在Site::BaseController中，我有一个呼叫给layout 'site'，在/layouts/site.html.haml中，我有一个呼叫

so, in Site::BaseController I have a call to layout 'site' and in /layouts/site.html.haml I have

= content_for :footer do
   -#Content for footer
= render :file => 'layouts/application'

然后在扩展了Site::BaseController的Site::BlogController中，我有layout 'site/blog'，在/layouts/site/blog.html.haml中我有

Then in Site::BlogController which extends Site::BaseController I have layout 'site/blog' and in /layouts/site/blog.html.haml I have

=content_for :header do
  %h1 HELLO WORLD!

= render :file => 'layouts/site'

然后将呈现如问题中所述嵌套的布局.很抱歉在我的问题中遗漏了这个.我应该读得更近些.

This then renders the layouts nested as described in the question. Sorry for missing this in my question. I should've read closer.
