Grails的順序由1到很多相關對象

Question

Grails的GSP我做這樣的事情

<g:each in="${testInstance?.testConfigs?}" var="t"> 

兩個類

class Test{ 
    static hasMany = [testConfigs:TestConfig] 
} 

class TestConfig { 
    Date dateCreated 
    Date lastUpdated 
    Test test 
    static constraints = { 
     dateCreated display:false 
     lastUpdated display:false 
     questionType inList:["Fill in the blanks","Multipl choice","True False"] 
    } 
} 

我怎樣才能改變每個循環，使testConfigs對象檢索的有序降序由dateCreated字段？

Answer 1

定義排序順序like it says in the docs不起作用嗎？

class Test{ 
    static hasMany = [testConfigs:TestConfig] 

    static mapping = { 
     testConfigs sort: 'dateCreated', order: 'desc' 
    } 
}
