Handling has_one nested resource in Rails 3

Question

I got a User model and a About model. The about model is a page where users have more info about them that due its nature is more appropriate to have it on a separate model

Answer 1

When using a has_one, it might make sense to declare it as a singular resource in your routes. Meaning

resources :users do
  resource :about # notice "resource" and not "resources"
end

And if you want to override the paths for new/edit, add a :path_names option to the resource/resources-call:

resources :about, :path_names => { :new => 'add', :edit => 'edit' }

The official documentation has lots of other tips and tricks for routing as well.

Answer 2

You can use scope and controller blocks to cut down on the verbiage:

  scope "/:username" do
    controller :abouts do
      get 'about' => :show
      post 'about' => :create
      get 'about/add' => :new
      get 'about/edit' => :edit
    end
  end

which produces:

     about GET /:username/about(.:format) {:action=>"show", :controller=>"abouts"}
           POST /:username/about(.:format) {:action=>"create", :controller=>"abouts"}
 about_add GET /:username/about/add(.:format) {:controller=>"abouts", :action=>"new"}
about_edit GET /:username/about/edit(.:format) {:controller=>"abouts", :action=>"edit"}
