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.
