1. Use the collection keyword with partials
2. Pass a collection to the render method
3. Handle empty collections

Let's go back to our store domain. We had an admin portion of the site where admins could check on their orders and invoices. We've changed it slightly so that, rather than static pages with stubs for orders, we've seeded the database with actual order data. Let's refactor the admin portion of the store to use partials and render collections.

We've provided a seed file so you can have some data to play around with –– run rake db:seed to seed the database.

1. Refactor the invoices/index.html.erb view to render a collection of partials with _invoice.html.erb.
2. Refactor the orders/index.html.erb view to render a collection of partials with _order.html.erb.
