Question

Actually, this is my problem. I have a rails app with a MainController, a HttpHelper and a ServiceHelper.

main_controller.rb

class MainController < ApplicationController
    include ServiceHelper
    def my_method
        Service.make_stuff
    end
end

service_helper.rb

module ServiceHelper
    class Service
        include HttpHelper
        def self.make_stuff
            http__foo
        end
    end
end
Service = ServiceHelper::Service

http_helper.rb

module HttpHelper
    def http__foo
        #stuff
        params[:bar].nil?
    end
end

If everything work well, this code should tell me if the :bar param exist, but I have a problem. Firstly, this code doesn’t work, it tells me that http__foo is not defined, certainly because the include HttpHelper in Service doesn’t work.

My second probleme is that if the include works, there will probably be a problem with the params variable. If I call this method (http__foo) in the controller, it will be fine, but I call this from a subclass, then I’m not sure it’s be reliable.

Answer 1

make_stuff is a class method. http_foo is an instance method. Hence, when you call http__foo from your make_stuff, it is like calling Service.http_foo() which is not defined. What is defined is Service.new.http_foo().

I don’t know what you want to do but in my humble opinion, by watching your code, it does not seem you are really familiar with Rails MVC concept and creating a MainController (why not use ApplicationController?), as well as the way you use your helpers is weird to me. It might be a good idea to restart from scratch.
