sorry my bad I didn't test with python2, 5ffc9e693c5f89759bc15e8cc8528922082fb511 fixes it, just rerun your migrations because I actually added the updatedAt column now.

(if the migration fails run 

$ rm -fr migrations/ && rm dev.db && flask db init && flask db migrate && flask db upgrade

thanks for bearing with me.
