how to order by data descending with findAll query using grails?

Question

Here is my code:

Notification.all.findAll{it.actionTeamBy != null && it.user.id == params?.getLong('user_id') && it.status == true}

Thank in advance!

Answer 1

You are looking for standard Iterable sorting that is done after the findAll call.

assert [3,4,2,7,4].sort() == [2, 3, 4, 4, 7]

So that would translate into something like this

Notification.all.findAll {
    it.actionTeamBy != null && it.status == true &&
            it.user.id == params?.getLong('user_id')
}.sort { a, b ->
    // implement sorting mechanism here
    // b.id <=> a.id // could work for you
}
