I enforce referential integrity on db-side and uncheck “Referential Integrity” on phpm-side.
Question:
Is there any downside of not enforcing “Referential Integrity” on phpm-side?
The only difference between db side and PHPMaker side is, if you enable from db side, then the error message you will see in the generated web app will came from the db. Therefore, you probably need to handle the error message by changing the error message as you want.
