I've got up to this point all fine and dandy, but I'm getting an error with the unit testing. I've copied and pasted all of the code from the examples and I'm still getting the same error. I'm on Mac OS X 10.5 btw.

Hermes:shovell graham$ rake test:units
(in /Users/graham/shovell)
rake aborted!
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.[]

(See full trace by running task with --trace)
Hermes:shovell graham$

And my story_test.rb:

require File.dirname(__FILE__) + '/../test_helper'

class StoryTest < Test::Unit::TestCase
  fixtures :stories

  def test_should_require_name
    s = Story.create(:name => nil)
    assert s.errors.on(:name)
  end
  
  def test_should_require_link
    s = Story.create(:link => nil)
    assert s.errors.on(:link)
  end
  
  def test_should_create_story
    s = Story.create(
      :name => 'My test submission',
      :link => 'http://www.testsubmission.com/')
    assert s.valid?
  end
end

Thanks a lot in advance!

After much head scratching, I found where the problem was - my db/database.yml wasn't indented properly. Only my development db had the proper indentation.

I didn't realise it would be so picky about these things - lesson learnt!

Yeah, it's one of the fun parts about YAML. It's pretty cool, actually, but I remember getting burnt by aspects like that when I first started using it. It's really quite simple, though, so you should have your brain wrapped around it in no time.
