le API design

A consumer needs to lookup a single user by their github name (jordanbyron). That consumer doesn't know the user's ID. There is a possibility to also search by email and twitter.

"/users.json?github=jordanbyron"
=> [{github: "jordanbyron", id: 1}]

When there are no results an empty array is returned

"/users.json?github=noexist"

# RSpec 2.0 syntax Cheet Sheet by http://ApproachE.com

# defining spec within a module will automatically pick Player::MovieList as a 'subject' (see below)
module Player
	describe MovieList, "with optional description" do
		  
	  it "is pending example, so that you can write ones quickly"
	  
	  it "is already working example that we want to suspend from failing temporarily" do
		pending("working on another feature that temporarily breaks this one")

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# and then use the :focus tag in your specs
