Rails Layout Extension, release 0.5.1 (Mar. 2009)

Feature

• simplifying content_for usage by extracting key/value pair from content_for data like YAML and setting them as content_for variables ��content_for��ʹ�ã���������YAML��key/value��ʽ����content_for����
• let erb file can determine layout by changing the default behavior of layout determining, just like java's sitemesh ͨ���ı�Ĭ�ϵ�layout��ȡ��ʽ��ʹerbҲ���Զ���layout������java��sitemesh
• use controller method if helper method requested from erb not exists ERB����helper�ķ��������ڣ����Զ�����controller�ķ���
• support theme template for field tag ֧��field tag������ģ��

Setup

• rlayout as gem put the following line into your rails initializer, or bottom of environment.rb ���������д���ӵ�rails��initializer�����environment.rb����� require 'rlayout'

• rlayout as plugin nothing need to do ����Ҫ��ʲô��

Usage

• simplifying content_for

<% content_for :config do %> title: This is my title panel: This is my panel <% end %>

that will do the same thing as the following:

<%- content_for :title do -%> This is my title <%- end -%> <%- content_for :panel do -%> This is my panel <%- end -%>

• determining layout in erb file <% content_for :config do %> #note��key layout won't be transferred to a content_for variable, it is only used to determine a view layout layout: happy <% end %>

• use theme template of field tag

class YourController form_theme :xhtml end

and see related code in folder "example/templates", the theme can be defined in tag with :theme, that will override theme definition in controller
