Hi all,

We are moving from having to remember to manually set the modifiedBy and modifiedDate values in our EOs when they are modified to overriding willUpdate() and pulling the loggedInUser from ERXThreadStorage.

We are overriding willUpdate() in our K12GenericRecord which all our EOs extend.

for example (very simplified to get the point across) :

willUpdate() {
super.willUpdate();
setModifiedBy((SystemUser) ERXThreadStorage.valueForKey("loggedInUser"));
}


As you can see, we are casting the results of the ThreadStorage as SystemUser which itself is a subclass of K12GenericRecord.

It seems odd to be importing a subclass into it's own superclass, but it since a SystemUser really is a standard EO and therefor is-a K12GenericRecord, it also seems correct.

We're not doing anything horribly wrong here, are we?

I don't think that would cause a problem... but you could always use an interface instead if it does.


You might also benefit by checking out the ERCore audit trail stuff. That can do ec notification based auditing in the background without touching any code in your EOs... It will automatically capture modifiedBy, modifiedDate, type of modification(insert, update, delete), the eo changed, and the changed values. And all you've got to do is set the ERXAuditKeys in your model and register your user class as the "actor" whenever your session awake()s. It's pretty awesome stuff.
