Pretty URLs with FriendlyId
If you are tired of model ids in the URL, overriding to_param can only get you so far. The friendly_id plugin can help by making it easy to generate a URL slug and maintain a history.

How I Test

Ransack allows you to easily build complex search forms. It also helps in adding sortable links and building a dynamic advanced search page.

There are many approaches to locking down an API. Here I start off with HTTP Basic authentication then move on to generating a unique token which can be passed through a URL parameter or HTTP header.

Non Active Record Model
This episode will show you how to make a model which isn't based on Active Record. You may want to do this if a resource isn't backed by the database.
