Helping devs understand concerns faster

A May Of WTFs

There is getting started app example here. So what I’m proposing is to expend this “getting started” section and showcase how other parts(including concerns) can be used in the context of real application.

For example on thing could be how controller concerns could be used on the scoped controllers:

class Posts::CommentsController < ApplicationController
  include PostScoped
  
  ...
end

class Posts::ParticipantsController < ApplicationController
  include PostScoped
  
  ...
end

module PostScoped
  extend ActiveSupport::Concern

  included do
    before_action :set_post
  end

  def set_post
    @post = Post.find(params[:post_id])
  end
end
