Today we had our weekly Artemis developer meeting.  Bill discussed his testing work with the auto_migrations plugin.  Seems it doesn’t handle certain changes made to the schema.rb, such as changing a null field to not null or changing the size of a varchar.  He’s going to try to whip it into shape using the meta data found in ActiveRecord::Base.connection.columns.

Later Jill came into mine and Bill’s office to discuss schema changes with regards to diseases and study groups.  David joined us after a short time.  Looks like we may use a polymorphic association for study_groups and anything connected to it.  Anything can appear under there, including non-disease studies such as ones for the Amish.

A brief discussion on how to pronounce “tuple” also occured.
