How to include order helper into different controllers?

Question

In my Rails application I have this:

class ProjectsController < ApplicationController

  include ApplicationHelper

  def index
    @payments = current_user.projects.custom_order
  end

  ...

end

module ApplicationHelper

  def custom_order 
    order("name ASC")
  end

end

However, in my index view I get this error:

undefined method 'custom_order' for #<Class:0x007f8be606ff80>

How can this be done?

I would like to keep the custom_order method in a helper module because I am using it across various different controllers.

Thanks for any help.

Okay . Just realized that it won't work. You cannot make order in helper method. As when you are doing .projects ... Then class is activerecords of class Project. Which is a model. Unless you use scope you cannot order any active record. — Pankhuri Kaushik, Dec 04 '13 at 19:54
Try to extend active record base class to add custom order method . http://stackoverflow.com/questions/2328984/rails-extending-activerecordbase. Refer this .. http://stackoverflow.com/questions/2328984/rails-extending-activerecordbase — Pankhuri Kaushik, Dec 04 '13 at 20:01

I know what you mean, but the right way is use model scopes:

class Project < ActiveRecord::Base
  #...

  scope :custom_order, order('name ASC')

  #...
end

Thanks but my intention is to use that scope across various different controllers. And to be honest my `custom_order` method is a bit more dynamic than the one I posted above for reasons of brevity. – Tintin81 Dec 04 '13 at 19:41

Move it to application controller.and make it a helper method.

Or include application helper module in application controller. So you will be able to access all application helper methods in all controllers.

I am doing that already. But it's not working and gives me the above error. – Tintin81 Dec 04 '13 at 19:44

Normally View Helpers are meant for rendering html based outputs, There you couldn't expect your model based queries.

Once you write a helper method in Application helper, It can be called in Any views.

Change your query like this

@payments = current_user.projects.order("name")

Or otherwise In your model Make it with scope.

scope :custom_order, order('name ASC')
