ActiveRecord tests

I am trying to get a working copy of the rails core setup, but I cannot
get ActiveRecord tests to pass. I get a couple hundred errors most of
are:

ActiveRecord::StatementInvalid: Mysql::Error: #HY000Field ‘type’ doesn’t
have a default value: INSERT INTO projects (name, id) VALUES
(‘Active Record’, 1)

What do I need to do to get ActiveRecord tests to pass?
