Grails 类的每个对象上的闭包

我试图对类的每个对象调用闭包，然后显示闭包返回的对象。 关闭日期为:

    def activitiesPlanned={
        cal.set(this.plannedStartDate)
        def planDateMonth=cal.get(Calendar.MONTH)
        def planDateYear=cal.get(Calendar.YEAR)
    }

我的电话是：

 def getActivitiesPlanned(int month,int year){
       countActivitiesPlanned=ProgressData.each{it.activitiesPlanned.findAllWhere(planDateMonth:month,planDateYear:year).count()}
    println countActivitiesPlanned
}

域类//编辑

package main
class ProgressData {
//String milestoneName
String taskId   //Added later
String taskDescription
String taskCategory
Integer plannedHours  
Integer actualHours      
Date plannedStartDate     
Date actualStartDate     
Date plannedEndDate     
Date actualEndDate     
Integer stepsCreated=0    
Integer stepsExecuted=0   
String status   //Originally Completed
String assignedTo
//String unplanned
String accepted //Added later
def ProgressData(){}

static constraints = {
   //milestoneName(blank:false)
   taskDescription(blank:false)
   taskCategory(blank:false)
   plannedHours(blank:false)
   actualHours(blank:false)
   id generator:"assigned",name:"taskId"
}

 Calendar cal=Calendar.getInstance()
 def activitiesPlanned={
        cal.set(this.plannedStartDate)
        def planDateMonth=cal.get(Calendar.MONTH)
        def planDateYear=cal.get(Calendar.YEAR)
    }
static hasMany=[defects:DefectData]

}

我得到：没有这样的属性：activitiesPlanned for class:main.ProgressData可能的解决方案：activitiesPlanned。可能有什么问题？

我想你不需要。每个{}而不是.sum{}

例如：

def listThing = [1,2,3]
def sumOfList = listThing.sum{it}
assert sumOfList == 6

另外，ProgressData是一个域类，因此不能使用它上面的.each{}。你必须做ProgressData.list.each{我指的是ProgressData.list.sum{我认为你在做的事情

另外，activitiesPlanned Close不会返回任何活动…

Progressdata是您的域类吗？您可以发布完整的代码示例。是的。Progressdata是我的域类。我将发布域类代码
