If you use the convention of using :notice, :warning and :error with your flashes, then this simple helper will allow you to display your flashes easily, and it supports the storage of ActiveRecord::Errors in flash[:error] as well.
def display_standard_flashes(message = 'There were some problems with your submission:') if flash[:notice] flash_to_display, level = flash[:notice], 'notice' elsif flash[:warning] flash_to_display, level = flash[:warning], 'warning' elsif flash[:error] level = 'error' if flash[:error].instance_of? ActiveRecord::Errors flash_to_display = message flash_to_display << activerecord_error_list(flash[:error]) else flash_to_display = flash[:error] end else return end content_tag 'div', flash_to_display, :class => "flash #{level}" end def activerecord_error_list(errors) error_list = '<ul class="error_list">' error_list << errors.collect do |e, m| "<li>#{e.humanize unless e == "base"} #{m}</li>" end.to_s << '</ul>' error_list end
