# File actionpack/lib/action_controller/metal/flash.rb, line 32 def add_flash_types(*types) types.each do |type| next if _flash_types.include?(type) define_method(type) do request.flash[type] end helper_method(type) if respond_to?(:helper_method) self._flash_types += [type] end end
Creates new flash types. You can pass as many types as you want to create flash types other than the default
notice in your controllers and views. For instance:
# in application_controller.rb class ApplicationController < ActionController::Base add_flash_types :warning end # in your controller redirect_to user_path(@user), warning: "Incomplete profile" # in your view <%= warning %>
This method will automatically define a new method for each of the given names, and it will be available in your views.
