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?

Hello Paul, 2006/4/28, Paul B. <email@example.com>: [...] > def test_find > user = User.find(@admin.id) > assert_equals(@admin.id,user.id) > end > > end [...] > 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 -- Jean-FranÃ§ois.

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.
