DisplayFlashHelper ================== Just a little helper to make it easier to display notice, warning, and error messages. It will only show flash[:success], flash[:notice], flash[:warning], or flash[:error] messages. There are some default styles and icons that can be used. rake display_helper:setup Example ======= In your controller: def create do_somthing flash[:notice] = 'Something has been done.' end In your view (layout or template): <%= display_flash %> And it will create: <div id="flash"> <div class="notice">Something has been done.</div> </div> Include the stylesheet in the <head> section of your layout: <%= stylesheet_link_tag 'display_flash_helper' %> or Geoffrey Dagley's original stylesheet: <%= stylesheet_link_tag 'flash_styles' %> Configuring =========== Options for display_flash_helper are optional and get their default values from the DisplayFlashHelper.flash_options hash. You can write to this hash to override default values on the global level: DisplayFlashHelper.flash_options[:error_class] = 'my_error' Available options (and their defaults) are: :flash_types => [:success, :notice, :warning, :error] :success_class => 'success' :notice_class => 'notice' :warning_class => 'warning' :error_class => 'error' :flash_id => 'flash' Default flash messages ====================== Add the following to ApplicationController (app/controllers/application.rb): include DisplayFlashHelper::FlashHelperMethods The following flash helper methods are now available for controllers instead of the static flash[:notice] = 'Note was successfully created.'-like messages: flash_created(@object) flash_create_failed(@object) flash_updated(@object) flash_update_failed(@object) Add the following to your I18n locale file (e.g. RAILS_ROOT/config/locales/#{I18n.locale}.local.yml): display_flash_helper: created: "{{obj}} was successfully created." create_failed: "{{obj}} could not be created." updated: "{{obj}} was successfully updated." update_failed: "{{obj}} could not be updated." TODO ==== - Use Rails I18n in flash helper methods; You may want to define/translate human names for objects in your I18n locale file; for example: activerecord: models: user: "Employee" ... - Use CSS sprite to combine images into one Notes ===== Style thanks to Janko Jovanovic's post http://www.jankoatwarpspeed.com/post/2008/05/22/CSS-Message-Boxes-for-different-message-types.aspx Knob Buttons Toolbar icons from http://itweek.deviantart.com/art/Knob-Buttons-Toolbar-icons-73463960 Silk Icons from http://famfamfam.com/lab/icons/silk/, released under the Creative Commons Attribution 2.5 License To display transparent png images correctly in IE6, see Angus Turnbull's solution http://www.twinhelix.com/css/iepngfix/ Copyright (c) 2008 Geoffrey Dagley, released under the MIT license
