Question

In the spring security generated class UserRole or SecUserSecRole (you could call it whatever you choose) there is a command to make a new UserRole() and save it with .save(flush:flush, insert:true)

What does that mean? What is it doing differently from .save(flush:true)?

Answer 1

From the Grails docs:

insert (optional) – When set to true will force Hibernate to do a SQL
INSERT, this is useful in certain situations when legacy databases
(such as AS/400) are involved and Hibernate cannot detect whether to
do an INSERT or an UPDATE
