我有两个简单的域类:
class Isa95EquipmentSpecification {
String equipmentClass
String equipment
String description
Float quantity
String quantityUOM
List<Isa95EquipmentSpecificationProperty> equipmentSpecificationProperties
static embedded = ['equipmentSpecificationProperties']
static constraints = {
equipment nullable: true, validator: {val, obj -> if (null == val && null == obj.equipmentClass) return ['bothNullable']}
equipmentClass nullable: true, validator: {val, obj -> if (null == val && null == obj.equipment) return ['bothNullable']}
description nullable: true
quantity nullable: true
quantityUOM nullable: true
}
}
和子域名:
class Isa95EquipmentSpecificationProperty {
String name
String description
String value
String valueUOM
Double quantity
String quantityUOM
static constraints = {
name nullable: false
description nullable: true
value nullable: false
valueUOM nullable: false
quantity nullable: true
quantityUOM nullable: true
}
}
我希望构建一个嵌入属性的组合文档我可以保存它只在父级上运行save()操作,但它不起作用。
我尝试在grails控制台上运行:
def prop1 = new isa95.productdefinition.Isa95EquipmentSpecificationProperty(name: 'prop-1', value: 'mad', valueUOM: '-')
def prop2 = new isa95.productdefinition.Isa95EquipmentSpecificationProperty(name: 'prop-2', value: 12.32, valueUOM: 'kilograms')
def spec = new isa95.productdefinition.Isa95EquipmentSpecification(equipment: '41500', description: 'eq-test', equipmentSpecificationProperties: [prop1, prop2])
spec.save(failOnError: true)
脚本运行正常但在db中我找到了这个。我期望找到使用嵌套列表填充的equipmentSpecificationProperies:
{ "_id" : NumberLong(9), "description" : "eq-test", "equipment" : "14500", "equipmentSpecificationProperties" : [ null, null ], "version" : 0 }
答案 0 :(得分:0)
指定列表类型:
List<Isa95EquipmentSpecificationProperty> equipmentSpecificationProperties
