hibernate - 非空属性引用一个 transient 值-必须在当前操作之前保存 transient 实例

Question

我有以下域名

class User {

    Boolean accountLocked
    String password
    Boolean passwordExpired
    Boolean enabled
    String username
    String name
    String surname
    String gender
    String urlPicture
    String cellphone
    String address
    Integer pc
    String permission
    String email
    Date created
    Boolean accountExpired

    static hasMany = [
        customerOnlines: CustomerOnline,
        partners: Partner,
        roles: Role,
        salesmans: Salesman,
        subsidiaries: Subsidiary
    ]

    static mapping = {
        tablePerHierarchy false
        id generator: 'identity'
        table '`user`'
        password column: '`password`'
        email unique: true
    }

    static constraints = {
        accountLocked nullable: true, default: false
        password nullable: true
        passwordExpired nullable: true, default: false
        enabled nullable: true, default: true
        username nullable: true, maxSize: 45
        name nullable: true, maxSize: 45
        surname nullable: true, maxSize: 100
        gender nullable: true, maxSize: 15
        urlPicture nullable: true
        cellphone nullable: true, maxSize: 50
        address nullable: true
        pc nullable: true
        permission nullable: true
        created nullable: true
        accountExpired nullable: true, default: false
    }

    class Subsidiary {

        String subsidiaryName
        Date dob
        User user

        static hasMany = [
            partners: Partner,
            phones: Phone,
            salesmans: Salesman
        ]
        static belongsTo = [Partner, User]

        static mapping = {
            id generator: "identity"
            version false
        }

        static constraints = {
            subsidiaryName nullable: true, maxSize: 100
            dob nullable: true
        }

问题是在尝试创建新的子公司时

    def save(Subsidiary subsidiary) {

    System.out.println(params)
    def usuario = new User(name:params.name,surname:params.surname,address:params.address,cellphone:params.cellphone,gender:params.gender,username:params.username,password:params.password,pc:params.pc)
    usuario.save flush:true
    def subsidiaria= new Subsidiary(name:params.namesub,user:usuario)


    subsidiaria.save flush:true



    request.withFormat {
        form multipartForm {
            flash.message = message(code: 'default.created.message', args: [message(code: 'subsidiary.label', default: 'Subsidiary'), subsidiary.id])
            redirect view: 'create'
        }
        '*' { respond subsidiary, [status: CREATED] }
    }
}

我收到错误not-null属性，在 subsidiaria.save flush:true上引用了null或 transient 值，但是我找不到问题，即使我使用 usuario.addToSubsidiaries(subsidiaria).save()，它也仍然无法正常工作，并且
一直给我同样的错误。

我发现问题出在 Controller 本身上，不幸的是我不得不像这样放置两个表的所有参数

     user.accountLocked=params.accountLocked
     user.password=params.password
     user.passwordExpired=params.passwordExpired
     user.enabled=params.enabled
     user.username=params.username
     user.name=params.name
     user.surname=params.surname
     user.gender=params.gender
     user.urlPicture=params.urlPicture
     user.cellphone=params.cellphone
     user.address=params.address
     user.pc=params.pc
     user.permission=params.permission
     user.email=params.email
     user.created=params.created
     user.accountExpired=params.accountExpired

立即我像

     user.save flush:true
     user.addToSubsidiaries(subsidiary)
     user.save flush:true

之后，两个表都使用提供的新信息进行了更新，看来grails无法同时处理2个不同的bean。
