A very basic and simple solution for Bootstrap 4:

application_helper.rb

module ApplicationHelper
  def bootstrap_class_for(flash_type)
    {
      success: 'alert-success',
      error: 'alert-danger',
      alert: 'alert-warning',
      notice: 'alert-primary'
    }[flash_type.to_sym] || flash_type.to_s
  end
end

application.html.erb

<!DOCTYPE html>
<html>
  <head>
    <!-- . -->
    <!-- . -->
  </head>
  <body>
    <div class='container'>
      <% flash.each do |type, content| %>
        <%= render 'partials/flash', type: type, content: content %>
      <% end %>

      <%= yield %>
    </div>
  </body>
</html>

_app/views/partials/flash.html.erb

<div class="alert <%= bootstrap_class_for(type) %> alert-dismissible fade show" role="alert">
  <button type="button" class="close" data-dismiss="alert" data-aria-label="Close">
    <span aria-hidden="true">&times;</span>
  </button>
  <div class="text">
    <%= content %>
  </div>
</div>

Small typo with https://gist.github.com/suryart/7418454#gistcomment-2584737
correct file name is app/views/partials/_flash.html.erb (mind the underscore)
