Little snippet to render flash messages using twitter bootstrap in Rails.

_flash_render.html.erb

<% [:notice, :error, :alert].each do |level| %>
  <% unless flash[level].blank? %>
    <div class="alert <%= flash_class(level) %>">
      <a class="close" href="#">×</a>
      <%= content_tag :p, flash[level] %>
    </div>
  <% end %>
<% end %>

application_helper.rb

module ApplicationHelper
  def flash_class(level)
    case level
    when :notice then "alert-info"
    when :error then "alert-error"
    when :alert then "alert-warning"
    end
  end
end

Nice!

Works perfect, thank you!

all inside view version (haml):

- flash_class = {notice: 'alert-info', error: 'alert-error', alert: 'alert-info'}
- [:notice, :error, :alert].each do |level|
  - unless flash[level].blank?
    %div{:class => "alert #{flash_class[level]}"}
      %a.close{:href => "#"} ×
      = content_tag :p, flash[level]
