Flash Message Conductor

A simple pattern for managing flash messages in your Ruby on Rails application.

Installation

This branch is only used for Rails 3. Still using Rails 2? Use https://github.com/planetargon/flash-message-conductor/tree/rails2 instead.

Add this line to your application's Gemfile:

gem "flash-message-conductor", "~> 2.0.1"

And then execute:

$ bundle

Or install it yourself as:

gem install flash-message-conductor

  add_message('foo')

Is the equivalent of:

  flash[:message] = 'foo'

Flash methods Keep, discard, and now are also supported

  add_message('foo', :state => :keep)

Is the equivalent of:

  flash[:message] = 'foo'
  flash.keep(:message)

Rails Controller helpers included:

  add_message(message)
  add_notice(message)
  add_error(message)
  add_alert(message)

  <%= render_flash_messages %>

Produces:

  <div id="flash_messages">
      <p class="message">You have successfully done XYZ...</p>
  </div>

Or... if you set an error:

  <div id="flash_messages">
      <p class="error">Oops! Something went bonkers!<p>
  </div>

Or:

  <% if flash_message_set? -%>
    # do something
  <% end -%>
