validates_uniqueness_of does not pass unit test

I am doing some very very basic unit testing. If I take away the uniqueness validation, the tests pass. Could this be a bug in Edge Rails?

Hi, could you post the test?

Thanks,

In my model: validates_uniqueness_of :number, :scope => :school_id

Unit test: def test_student_CRUD     student = Student.new :school_id => @john.school_id, :number => @john.number

    assert student.save     student_copy = Student.find(student.id)     assert_equal student.number, student_copy.number     student.number = "7777"     assert student.save     assert student.destroy   end

Fixture: john_doe:   id: 1   school_id: 1   account_id: 1   family_id: NULL   first_name: John   last_name: Doe   number: 9999

Thanks for any help!

So what actually happens when you run this test, and what are you
expecting it to do?

My reading says that it should fail on the first student.save line.
(And the test will, of course, pass if you remove the uniqueness
validation.)

You are correct, it fails on the on the save. If I remove it, it does pass. I want it to pass with the validation.

Why does it fail on the student.save line? the number is unique as there are no other student fixtures.
