我面临 Grails 模型关联的问题。这是问题：

  • 订阅者和客户是从 PartyRole 扩展而来的。
  • 一个客户可能有很多订阅者，一个订阅者属于客户。
  • 一个Party可能有很多PartyRole。
  • Person 和 Organization 是从 Party 扩展而来的。
  • 一个人属于组织。
  • 一个人有许多个人资料，一个个人资料属于个人。

现在我想编辑当前登录的用户（订阅者），它基本上是组织类型，意味着具有组织属性，如 orgName 和 orgSize。

我可以使用登录用户（订阅者）找到人员（名字和姓氏）和个人资料（电子邮件）详细信息，但无法获取组织详细信息。代码如下。

 def profile = {
    Subscriber loggedinSubscriber = Subscriber.get( springSecurityService.principal.id )
    if (loggedinSubscriber == null){
      redirect(controller: "login" , action:"login");
    }
    else{
      println loggedinSubscriber
      Party person = Person?.get(loggedinSubscriber.party.id)
      Party org = Organization?.get(loggedinSubscriber.party.id)
      Profile profile = person?.profile
      [userInstance: person, authorityList: sortedRoles()]
    }
  }

当我尝试获取组织详细信息时

Party org = Organization?.get(loggedinSubscriber.party.id)

我得到了空值，但以同样的方式，我可以使用登录用户（订阅者）获取人员详细信息，并且两者都是从 Party 扩展的。`

关于如何获取组织详细信息的任何想法。

人：

package com.vproc.member

import com.vproc.enquiry.Enquiry;
import com.vproc.enquiry.Membership;
import com.vproc.enquiry.Notification;
import com.vproc.enquiry.Team;

class Person extends Party{

    String firstName
    String lastName

    Profile profile
    static belongsTo = [Organization]

    static constraints = {
        lastName nullable:true
        firstName blank:false

    }

}

**Organization:**

package com.vproc.member

import java.util.Date;

class Organization extends Party{

    String orgName 
    Person contact
    int orgSize
    boolean isVendor 

    static constraints = {
    }
}

轮廓：

package com.vproc.member

import java.util.Date;

import com.vproc.enquiry.Enquiry;
import com.vproc.enquiry.Membership;
import com.vproc.enquiry.Team;

class Profile {

    String emailAddress  //  field governed by privacy policy
    String phoneNumber   //  field governed by privacy policy
    Date dateCreated
    Date lastUpdated
    boolean isDefaultProfile
  String status
    static belongsTo = [person:Person]
    //ProfilePrivacyLevelEnum privacyLevel = ProfilePrivacyLevelEnum.Private

    static constraints = {
    }
}

只需更改 Person 域类

static belongsTo = [Organization]

至

static belongsTo = [organization:Organization]

并使用 person.organization 从人员实例访问组织信息
