Question

当我尝试在静态脚手架中创建新的Employee时，我收到以下错误：

错误500：内部服务器错误

URI       / file-tracker / employee / save Class       org.hibernate.StaleStateException消息       批量更新从update [0]返回意外的行数;实际行数：0;预期：1

第38行   的grails-app /控制器/组织/ simpragma / EmployeeController.groovy

围绕PageFragmentCachingFilter.java的第191行

有什么问题？

package org.xyz

class Employee {
    String name;
    String department;
    String role;
    String userId;
    String pw;

    static mapping = {
        table 'employee'
        version false
        id  name: 'userId'
        id generator: 'native'
    }

    static hasMany = [toAllocations: Allocation, fromAllocations: Allocation]

    static mappedBy = [toAllocations: 'toEmployee', fromAllocations: 'fromEmployee']
    static constraints = {
        department nullable : true
            role nullable : true    
    }
}

package org.xyz

class Allocation {

    static hasOne = [file:File, toEmployee:Employee, fromEmployee:Employee, remark:Remark]
    static mappedBy = [toEmployee: 'toAllocations', fromEmployee: 'fromAllocations' ]

    static constraints = {
        remark nullable: true
    }
}

package org.xyz

class File {
    String fileNumber;
    Date requestedDate;
    String requestedBy;
    String priority;
    Double budget;
    String requestedByDepartment;
    String subject;

    static mapping = {
        id  name: 'fileNumber'
        version false
        id generator: 'native'
    }   
    static hasMany = [allocations: Allocation]  
    static constraints = {
        fileNumber nullable : true
        priority nullable : true
        budget nullable : true
    }
}

package org.xyz

class Remark {
    String remark;
    Date remarkDate;

    static belongsTo =  [allocation: Allocation];
    static constraints = {
    }
}

就我而言，出于测试目的，我试图将自己的id分配给对象。如果在保存期间应该生成id，我就不能这样做。
