MetaOnRails DRYs up your page meta tags. It is a very simple Rails plugin to help you customize your pages' meta tags a little bit easier.
Add this to your Gemfile:
gem "meta_on_rails"
Add the following code to the layout (e.g. app/views/layout/application.html.erb), be sure to put it in the head tag:
<head>
<%= display_meta(:keywords => "default,keywords", :description => "default description") %>
</head>
Default meta values can be set. In the above example, these two meta tags will be generated if they're not overridden on the views:
<meta name="description" content="default description" />
<meta name="keywords" content="default,keywords" />
Then add this code to the view to set meta tags on that page:
<% set_meta(:keywords => 'my,keyword', :generator => 'a bad <script /> generator') %>
The output html will be like this:
<meta name="generator" content="a bad generator" />
<meta name="description" content="default description" />
<meta name="keywords" content="my,keyword" />
Facebook support
<% set_meta(:title=>"my title", :facebook=>{:title=>"album title test", :type=>"og_mysite_dev:album"}) %>
The output html will be like this:
<meta name="title" content="my title"/>
<meta property="og:title" content="album title test"/>
<meta property="og:type" content="og_mysite_dev:album"/>
