About

If I find myself doing something over and over in Rails or if I come across a good best practice, then I'd document it here for future reference.

flash.md

Flash

Create the file shared/_flash_message.html.erb and add the following:

<div class="flash_messages">
  <% flash.each do |key, value| %>
    <%= content_tag(:div, value, class: "flash flash_#{key}") %>
  <% end %>
</div>

In layouts/application.html.erb we render the flash messages as follows:

<%= render 'shared/flash_messages' unless flash.empty? %>
