Hi,
Could anyone share the impelmentation of your JPA demo in GAE?
Actually I encounter some problem during deploy them in GAE.
a. The keys, GAE do not like Long as Key in OneToMany relation, So I use the
Key type provided by GAE
b. Model.mergeAndFlush(author) did not work as I expected. It could not
update, and only do insert. So I changed the code
if (author.id == null) {
Model.persistAndFlush(author)
} else {
val tmp = Model.find(classOf[Author], author.id)
tmp.get.name = author.name
Model.mergeAndFlush(tmp.get)
}
I think it is some attach/detach problem.
Thanks
