Use jquery.csrf (https://github.com/swordray/jquery.csrf).

• Rails 5.1 or later

  $ yarn add jquery.csrf
  

  //= require jquery.csrf
  

• Rails 5.0 or before

  source 'https://rails-assets.org' do
    gem 'rails-assets-jquery.csrf'
  end
  

  //= require jquery.csrf
  

• Source code

  (function($) {
    $(document).ajaxSend(function(e, xhr, options) {
      var token = $('meta[name="csrf-token"]').attr('content');
      if (token) xhr.setRequestHeader('X-CSRF-Token', token);
    });
  })(jQuery);
