How to add favicon to ActiveAdmin in rails 3

Question

How can I add a favicon in Active Admin. I am using rails 3.2 and active admin 0.4.3

Answer 1

Though this question is about an older version of ActiveAdmin, as of this commit ActiveAdmin supports favicons in the initializer. Around line 145 of active_admin.rb for me:

  # == Setting a Favicon
  #
  # config.favicon = '/assets/favicon.ico'

HTH the next person who comes along. I almost did the top-voted answer...

Answer 2

Until they support favicon you can do the trick:

$(document).ready(function(){

  $('head').append("<link href='favicon.ico' rel='shortcut icon'>");

});
