stevenharman / factories.rb

Created November 30, 2011 18:42

What am I missing about Ruby blocks that the following happens in factory_girl?

	sequence(:username) { \|n\| "bob-#{n}" }
	email { \|u\| "#{u.username}@example.com" }
	password 'password123'

	# the following works:
	factory :bob do username 'bob' end

	# but this does not:

stevenharman / music_library.rb

Created December 11, 2011 01:41

When wrapping AR behind an intentional interface, go explicit or generic/idiomatic?

	belongs_to :user
	belongs_to :album
