我如何使用 content_for 在 :yield 中放入一些东西 [英] How can I use content_for to put something in :yield

问题描述

我使用的是 ruby​​ 1.9.2、rails3.

I am in ruby 1.9.2, rails3.

所以我的网站有一些结构，

So My website has some structures,

我想把菜单放在我的网页中间.

and I want to put menu in a middle of my webpage.

我正在做类似的事情(在 application.html.erb 文件中)

I am doing something like (within application.html.erb file)

blahblahblah
<div id="menu">
   <%= yield :menu %>
<div>
blahblhablah

我有一个文件 menu.html.erb，其中包含该站点的菜单结构.如果我想使用 ./layout 文件夹中的文件作为该 yield :menu 的一部分，我该怎么办?我想知道，是否必须为每个控制器以及每个函数使用 content_for ......顺便说一句，每个控制器的 menu.html.erb 会有所不同，所以这就是我放弃它的原因.

I have a file menu.html.erb which has menu structure for the site. What can I do if I want to use a file within ./layout folder to be used to be part of that yield :menu? I was wondering, if I have to use content_for for every controller, and within every functions... Btw, menu.html.erb will be different for each controller, so thats why I am yielding it.

总而言之，我只想在几乎所有地方都包含一个通用的共享 menu.html.erb.

In conclusion, I just want to include one common shared menu.html.erb pretty much everywhere.

推荐答案

您可以在视图中执行以下操作:

You could do something like this in your views:

<% content_for(:menu) do %>
  <%= render :partial => "/layouts/user_menu.html.erb" %> 
<% end %>

您可以尝试将其与 controller.controller_name 结合使用(不确定这是否适用于 Rails3)并自动为每个控制器加载不同的菜单.

You could try to combine this with controller.controller_name (not sure this works for Rails3) and load a different menu for each controller automatically.
