Ruby on Rails: Controller Not Evaluating Method

Question

The next comment button should be directed to http://localhost:3000/articles/14/comments/70 .

What it currently executes is: http://localhost:3000/articles/14/comments/56/next_comment

How does one fix this?

#button
= link_to "next comment", next_comment_article_comment_path(@article, @comment)

#controller
class CommentsController < ApplicationController

  def next_comment 
    @comment ||= @scope.next(@comment)
  end

  def scope
    @scope ||= @article.comments
  end
end

UPDATE

#routes.rb
resources :articles do
 resources :comments do
  member do
    get 'next_comment'
  end
 end
end

Answer 1

Run rake routes and check if there is a route to next_comment_article_comment_path(@article, @comment)

And try whith: article_comment_next_comment_path(@article, @comment)
