Ruby on Rails: Declare a controller method as a helper
From Rails doc (http://api.rubyonrails.org/classes/AbstractController/Helpers/ClassMethods.html).
The following makes the current_user controller method available to the view:
class ApplicationController < ActionController::Base
helper_method :current_user, :logged_in?
def current_user
@current_user ||= User.find_by_id(session[:user])
end
def logged_in?
current_user != nil
end
endIn a view:
<% if logged_in? -%>
Welcome, <%= current_user.name %>
<% end -%>Written by Yannis Jaquet
