I'm having trouble seeding my database using seed.rb, specifically where table relationships are concerned.

Here's a sample of the code:

# seed.rb
user = User.find_or_create_by_login(  
  :login => "myname",  
  :email => "[email protected]",  
  :user_type => "Admin",  
  :password => "admin",  
  :password_confirmation => "admin")

project = Project.find_or_create_by_user_id(
  :user_id => user.id,
  :name => "Test Project")

When project is created (along with other unrelated parameters I've left out from above), user_id is empty. How can I get this to work?
