ActiveRecord 7.1 added first-party support for composite primary keys, which changed the way the
primary_key
method behaves; specifically, in cases where a model or table has a composite primary key, this will return an array of attributes rather than just one.Given this gem already has support for composite primary keys through the
composite_primary_keys
gem, I just extracted out the work done there to support Rails 7.1's approach.Closes #685.
