The Grails Framework 5.1.8

(Quick Reference)

sort

Customizes the default property to sort by for query results.

class Book {
    ...
    static mapping = {
        sort "releaseDate"
    }
}

Usage: sort(string/map)

By default results are sorted by creation date, and you can specify the column to order by in a query:

def results = Book.list(sort:"title")

However, you can also configure the default sort property:

static mapping = {
    sort "title"
}

in which case the sort argument is no longer needed. You can also control the sort order:

static mapping = {
    sort title: "desc" // or "asc"
}
