Generic ModelCompanion
Pawan Kumar
Hi All,
Although the below code works after repeating it for various types of users such as APIUser, SystemUser etc.
object APIUser extends ModelCompanion[APIUser, ObjectId]{......}
object SystemUser extends ModelCompanion[SystemUser, ObjectId]{......}
Any thoughts on how to make it generic enough so that byId and other methods (common for all types of users) can be placed in one trait and used by all other user types?
Thanks
Pawan
