The ACES Train from NY to AC takes longer than driving. Its hard to convince someone of the convenience and pollution impacts of taking a train when it takes longer than driving. COM’ON ‘MERICA your trains suck.

Don’t you hate that lipsum.com makes you choose 5 paragraphs and hit “Generate Lorem Ipsum” before giving you Lorem Ipsum? TAKE FOREVER. Now you can reference loremipsum.erictarn.com instead for all your ipsum needs.

A less annoying database.yml file when you use the same database for all three environments

defaults: &defaults
    adapter: mysql
    encoding: utf8
    reconnect: false
    pool: 5
    username: admin
    password: welcome1

development:
    database: friendster_dev
    <<: *defaults

test:
    database: friendster_test
    <<: *defaults

production:
    database: friendster
    <<: *defaults

How come its always so hard to find documentation for the database.yml file?

/test/fixtures/users.yml

<%
  def auto_increment
    @id ||= 0; @id += 1
  end
%>
tommy:
  id: <%= auto_increment %>
  email: tommy@thedocks.com
  created_at: <%= 6.months.ago.to_s(:db) %>
gina:
  id: <%= auto_increment %>
  email: gina@jerseydiner.com
  created_at: <%= 1.minute.ago.to_s(:db) %>

/test/unit/user_test.rb

fixtures :users

def test_can_access_tommy_fixture
  assert(users(:tommy) != nil)
end

Import your fixture records into the current environment: rake db:fixtures:load

Sometimes when things get crazy, you need to reference the default stuff.
