Complete Grails/Groovy newby here ...
My create screen has one Book per row (isbn, title). I want to
enforce unique isbn and unique name. I can code this contraint in the
Book class, but when I Book.findByIsbn(val), I am only searching on
the persisted Books, not on those that have not yet been saved. If I
have the same Book multiple times on the create screen, but none of
which are saved, then no error is detected by the contraints. When I
call save(), the first one is saved and the others are discarded.
The screen is defined as an array of Strings. Should I be using a
Command object - Books, or maybe Book[] ?
I have been playing around with passing the array of input parameters
to the Book class for picking up by the contraints ....
I have been looking to put the validation in the BookController, but I
can't work out how to attach the error condition to the Book so that
it gets displayed on the screen.
I think I'm tying myself in knots ... time to ask for some help
Thanks
Martin
