我不知道如何在碧玉报告中呈现来自 Grails 的列表属性
我的域类如下所示：
class Project {
String name
String division
List divisions
String toString(){
"$name"
}
static hasMany = [divisions : Division ]
...
而划分域类就到这里了
class Division {
String name
String divisionResponsible
String createDate
...
项目控制器看起来像这样
class ProjectController {
def scaffold = true
def index = {
redirect(action : list)
}
def createReport = {
def projectreport = Project.getAll([params.project_id])
chain(controller:'jasper',action:'index',model:[data:projectreport],params:params)
}
}
我用 iReport 创建了一个 jasper 报告，效果很好。我在列表中添加了字段，它们通过访问例如 $F{name} 显示在报告中，但我不知道如何添加部门列表。我想要一个每行一个元素的列表。
更新jrxml 文件添加：

更新 2：
我设法通过在碧玉报告中使用以下变量来访问列表元素
$F{divisions.[0].name}
$F{divisions.[1].name}
现在的问题是，这在真实报告中并不能真正使用，因为我不知道列表中有多少元素。
有没有办法遍历碧玉报告中的列表元素？
