Rails - Apr 2006 - Accessing fixtures from unit tests

I have set up some fixtures in test/fixtures/users.xml:

# Read about fixtures at http://ar.rubyonrails.org/classes/Fixtures.html
admin:
  id: 1
  username: admin
  password: admin
pbarry:
  id: 2
  username: pbarry

I have a unit test for my user model:

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

class UserTest < Test::Unit::TestCase
  fixtures :users

  def test_find
    user = User.find(@admin.id)
    assert_equals(@admin.id,user.id)
  end

end


When I run the test, I get this:

C:\ruby\workspace\lms>ruby test/unit/user_test.rb
Loaded suite test/unit/user_test
Started
E
Finished in 0.156 seconds.

  1) Error:
test_find(UserTest):
RuntimeError: Called id for nil, which would mistakenly be 4 -- if you
really wanted the id of nil, use object_id
    test/unit/user_test.rb:7:in `test_find''

1 tests, 0 assertions, 0 failures, 1 errors

Why is @admin nil?  Shouldn''t it be populated from the fixture?

Because the instantiated fixtures are disabled by default.
You shoud use sth like :

  admin = users(:admin)
  user = User.find(admin.id)
  assert_equals admin.id, user.id

Thanks, that did it.  This must be one of those new to Rails 1.1 things?  We
desparately need a new version of Agile Web Dev with Rails updated for 1.1.
I know the plan was to not "break the book", but I think there a
number of
these little details that have unfortunately done that.
