ContentForOnce

Gem Version Build Status

Seems like content_for, content_for_once embed the HTML tags(especially, javascript_include_tag and stylesheet_link_tag) just only once.

Usage

Add this line to your Rails application's Gemfile:

gem 'content_for_once'

Prepare some layout file.

-# layout.html.haml
%html
  %head
    = yield :css
    = yield :js

Write content_for_once block, and write tags that you want to use it only once in the page.

-# sample.html.haml
- content_for_once :css do
  = stylesheet_link_tag "sample1"

= render 'sample_mini'

-# _sample_mini.html.haml
- content_for_once :css do
  = stylesheet_link_tag "sample1"
  = stylesheet_link_tag "sample2"

Then rendered page has unique tags!

<html>
  <head>
    <link rel='stylesheet' href='sample1.css'>
    <link rel='stylesheet' href='sample2.css'>
  </head>
<html>
