## Question:

Tag: ruby,ruby-on-rails-4,method-overriding

In rails app, how are helpers included in viewcontrollers, and what's the order of includion(which helper is included first, second, so on)?

Also, are all helpers available to views? If so, does the inclusion order same as the view's corresponding controller?

Any controller can have a corresponding helper.

For example if you have a controller named Question (questions_controller.rb), it can have a helper named questions_helper.rb. The question helper is accesible only to the views corresponding to the question controller.

Besides you will have an Application helper (application_helper.rb) which is accessible to all the views in the application.

All helpers are not available to views by default. But you can include other helpers in a helper like this:

module MyHelper
include QuestionsHelper
end


You can also use a helper inside a controller like:

class MyController < ApplicationController
include MyHelper

def my_method
...
end
end
