ContentForOnce
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>
