Where to use Ruby methods for Rails controllers?

Question

I have some Ruby methods that need certain (or all) controllers. I tried putting them in /app/helpers/application_helper.rb . I used this for the methods that will be used in the views. But controllers do not see these methods. Is there another place I should put them, or do I need to access these helper methods in different ways?

Using the latest stable Rails.

Answer 1

You must define a method inside the ApplicationController .

Answer 2

For Rails 4, problems are the way to go. There is a decent article here http://richonrails.com/articles/rails-4-code-concerns-in-active-record-models

In essence, if you look in your folder with controllers, you will see a folder with problems. Create a module there in these lines

 module EventsHelper def do_something end end 

Then in the controller just turn it on

 class BadgeController < ApplicationController include EventsHelper ... end 

Answer 3

you must define the methods inside the application controller, if you have several methods, then you can follow these steps

 class ApplicationController < ActionController::Base helper_method :first_method helper_method :second_method def first_method ... #your code end def second_method ... #your code end end 

You can also include auxiliary files as shown below.

 class YourController < ApplicationController include OneHelper include TwoHelper end 

Answer 4

You can call any helper methods from the controller using view_context , for example

 view_context.my_helper_method 

Answer 5

Ryan Bigg's answer is good.

Another possible solution is to add helpers to your controller:

 class YourController < ApplicationController include OneHelper include TwoHelper end
