Issue while trying to exclude articles with specific tag using Rails 5 and polymorphic association

ActiveRecord excluding polymorphic association issue

Considering this situation with Rails 5: I have an Article model and a Tag model. An article has many tags, and a tag can belong to many articles. My schema then looks like this:

class Article < ApplicationRecord
  has_many :taggings, as: :taggable
  has_many :tags, through: :taggings
end

Try to understand how to use RequireJS with tools creating single minified-concatenated script file.

Context

I have a bit experience in JavaScript development but I'm quite new in modern development tools such as Yeoman, Grunt or Bower. But I can create webapps with RequireJS, separate logic with Backbone.js and use templating with Handlebars. I am aware of what's going on.

I saw that these tools leads you to concat files, which is great, in my case I want to speak about JavaScript files. I can't understand how it works.

I love RequireJS

With RequireJS, I can separate files, for example if I'm using Backbone.js, every model, every view can be a file. If my application is big enough, some pages will need some models and some other pages will need some other models. And thanks to RequireJS I can load only the models (I mean the files, then) I need.
