grails中缺少PropertyException

当我试图显示我的一个域的视图时出现问题。我建立了一个求和一些数量的方法，但我有这个错误，我不知道如何修复它。我知道可变奖励不存在，但我在我的领域中有这个价值。这是控制器中唯一给出错误的方法的代码

URI /Rewards/customer/show/1
Class groovy.lang.MissingPropertyException
Message No such property: awards for class: rewards.Customer

Around line 14 of grails-app/services/rewards/CalculationsService.groovy
11: 
12: def getTotalPoints(customerInstance){
13:     def totalAwards = 0
14:     customerInstance.awards.each{
15:         totalAwards = totalAwards + it.points
16:     }
17:     customerInstance.totalPoints = totalAwards

Around line 33 of grails-app/controllers/rewards/CustomerController.groovy
30: 
31: def show(Long id){
32:     def customerInstance = Customer.get(id)
33:     customerInstance = calculationsService.getTotalPoints(customerInstance)
34:     [customerInstance: customerInstance]
35: }
36: 

控制器（CustomerController.groovy）

模特儿

class Customer {

    String firstName
    String lastName
    Long phone
    String email
    Integer totalPoints
    static hastMany = [awards:Award, orders:OnlineOrder]

    static constraints = {
        phone()
        firstName(nullable: true)
        lastName(nullable: true)
        email(nullable: true, email: true)
        totalPoints(nullable: true)
    }
}

模范奖

package rewards

class Award {
    Date awardDate
    String type
    Integer points
    static belongsTo = [customer:Customer]

    static constraints = {
    }
}

服务（CalculationService.groovy）

您在客户域中拼写的

有许多

错误

static hastMany = [awards:Award, orders:OnlineOrder]

应该是

static hasMany = [awards:Award, orders:OnlineOrder]

---

您能提供模型客户的代码吗？模型客户类客户{String firstName String lastName Long phone String email Integer totalPoints static hastMany=[awards:awards，orders:OnlineOrder]静态约束={phone（）firstName（null:true）lastName（nullable:true）email（nullable:true，email:true）totalPoints（nullable:true）}尝试运行grails clean，看看它是否有帮助否，我清理了项目，但我有相同的错误您添加了“奖励”吗属性？您是否在数据库中插入了没有此属性的客户？如果是，您需要清理数据库

static hastMany = [awards:Award, orders:OnlineOrder]

static hasMany = [awards:Award, orders:OnlineOrder]
