<em>Powerful, Effective, and Efficient Full-Stack Web Development</em>
As a Rails developer, you care about user experience and performance,
but you also want simple and maintainable code. Achieve all that by
embracing the full stack of web development, from styling with
Bootstrap, building an interactive user interface with AngularJS, to
storing data quickly and reliably in PostgreSQL. Take a holistic view of
full-stack development to create usable, high-performing applications,
and learn to use these technologies effectively in a Ruby on Rails
environment.

Anything that XML can do, JSON can too...
edit app/controllers/products_controller.rb
def who_bought
@product = Product.find(params[:id])
@latest_order = @product.orders.order(:updated_at).last
if stale?(@latest_order)
respond_to do |format|
format.html
format.xml { render xml: @product.to_xml(include: :orders) }
format.atom
format.json { render json: @product.to_json(include: :orders) }
end
end
end
Fetch the data in JSON format
curl --max-time 15 --silent --user dave:secret http://localhost:3000/products/2/who_bought.json

Customize the xml
edit app/views/products/who_bought.xml.builder
xml.order_list(:for_product => @product.title) do
for o in @product.orders
xml.order do
xml.name(o.name)
xml.email(o.email)
end
end
end
Change the rendering to use templates
edit app/controllers/products_controller.rb
def who_bought
@product = Product.find(params[:id])
@latest_order = @product.orders.order(:updated_at).last
if stale?(@latest_order)
respond_to do |format|
format.html
format.xml
format.atom
format.json { render json: @product.to_json(include: :orders) }
end
end
end
Fetch the (much streamlined) XML
curl --max-time 15 --silent --user dave:secret http://localhost:3000/products/2/who_bought.xml
<order_list for_product="Rails, Angular, Postgres, and Bootstrap">
