Hello Eric,
why not simply think of the workitem as a task ?
It is much simpler.

As said, why not simply think of the "workitem" as a "task" ?

Why are you using SQL statements directly ?
In Rails you have ActiveRecord, it's an ORM. ORM means "Object to Relational

Please teach yourself about ActiveRecord.
