Rails - Apr 2006 - Bug in validates_associated?

Here is the setup:

Windows XP, InstantRails, MySQL 14.7, Ruby 1.8.4, Rails 1.1.2

MODEL:

class Office<ActiveRecord::Base
  has_many :users
end

class User<ActiveRecord::Base
  belongs_to :office

  validates_presence_of :office_id
  validates_associated  :office

  <....other stuff...>
end

UNIT_TEST test/unit/user_test.rb

  def test_associations
    u = User.new
    u.office_id = 2222 # Invalid office id
    assert !u.save     # Expected because of the invalid office id

    u.office_id = 2    # Valid office ID, found in fixtures
    assert u.save      # This works! So far, so good

    u.office_id = 2222
    assert !u.save     # THIS SHOULD FAIL, BUT DOES NOT
  end

Can someone explain this behavior?

thanks

You probably want to replace the two validation statements you''re
using with:
              validates_presence_of :office

The office attribute will be nil when office_id is not set to the
id of an existing office record, but validates_associated will
pass because there''s no associated object to check.
