nested routes for namespaces

gistfile1.rb

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

BCX::Application.routes.draw do  
  draw :projects # => config/routes/projects.rb

  namespace :admin do
    draw :projects # => config/routes/admin/projects.rb
  end

  root to: 'projects#index'
end

I've been experimenting, and this doesn't work with a simple substitution because scope[:path] returns the scope prefixed with a slash. I have found that the following works though:

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

BCX::Application.routes.draw do  
  scope "/admin" do
    draw :projects # => config/routes/admin/projects.rb
  end
end

Bonus is that it works for namespace too! :-)

BCX::Application.routes.draw do  
  namespace :admin do
    draw :projects # => config/routes/admin/projects.rb
  end
end

Hey, that's awesome! I've updated my routes file and it works.
