Site-Wide Global Variables in Ruby on Rails

For the sites built using PHP, it’s common practice to include a common config.php file which contains global variables accessible on every page, for example:

<?php
// config.php
$site_name = "Random Sequence";
$site_url = "http://www.randomsequence.com";
?>

To display these global variables in a view:

<?php echo $site_name; ?>
<?php echo $site_url; ?>

To replicate this functionality in Rails, you can define methods in the site-wide /app/helpers/application_helper.rb, for example:




Methods added to this helper will be available to all templates in the application.



module ApplicationHelper
  def site_name
    "Random Sequence"
  end



def site_url
    "http://www.randomsequence.com"
  end

end

To use these helpers in your view:

<%= site_name %>
<%= site_url %>
