(Quick Reference) # 6.5.3 Default Sort Order - Reference Documentation Authors: Graeme Rocher, Peter Ledbrook, Marc Palmer, Jeff Brown, Luke Daley, Burt Beckwith, Lari Hotari Version: 2.3.8 ## 6.5.3 Default Sort Order You can sort objects using query arguments such as those found in the list method:
    def airports = Airport.list(sort:'name')
However, you can also declare the default sort order for a collection in the mapping:
    class Airport {
        …
        static mapping = {
            sort "name"
        }
    }
The above means that all collections of `Airport` instances will by default be sorted by the airport name. If you also want to change the sort order , use this syntax:
    class Airport {
        …
        static mapping = {
            sort name: "desc"
        }
    }
Finally, you can configure sorting at the association level:

    class Airport {
        …
        static hasMany = [flights: Flight]    static mapping = {
            flights sort: 'number', order: 'desc'
        }
    }
In this case, the `flights` collection will always be sorted in descending order of flight number. These mappings will not work for default unidirectional one-to-many or many-to-many relationships because they involve a join table. See this issue for more details. Consider using a `SortedSet` or queries with sort parameters to fetch the data you need. | Quick Reference (hide)
