  # It also works through association's associations, like `joins` does:

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

Sinatra like routes in Rails controllers

A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.

dhh

class ActionDispatch::Routing::Mapper
  def draw(routes_name)
    instance_eval(File.read(Rails.root.join("config/routes/#{routes_name}.rb")))
  end
end

BCX::Application.routes.draw do
  draw :api
  draw :account
  draw :session
