def b = Book.get(1) b.title = "Blah" b.discard() // changes won't be applied now
Discards any changes that have been made to a persistent instance.
discard method informs the persistence context that the instance should not be saved. The
discard method is equivalent to using Hibernate’s evict method.
|Note that this method will not clean or reset the object with the original values; it will just prevent it from being automatically saved by Grails.|
