Adding content to a layout from a partial
layout, ruby-on-rails
Solution
You have to use the content_for tag.
<% content_for :head do -%>
*your code here*
<% end -%>
So, the code you put inside will apear on the head of your html file.

Problem
Suppose I have an application layout, and in their I yield for :head content as follows: ``` <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8" /> <title></title> <%= stylesheet_link_tag 'scaffold' %> <%= yield(:head) %> </head> ``` Suppose in that same application layout I call a partial to render the main menu. ``` <body> <p style="color: green"><%= flash[:notice] %></p> <!-- Main Menu --> <%= render :partial => 'menu/menu_main' %> </body> ``` Is there any way, from within my _menu_main.erb partial to add content to the :head section of my application layout (say to add some css)?
