type ObjectX struct {
	Id int64    `gorm:"Id"`                              // id
	ParentId   int64    `gorm:"Parent_Id"`        // 父节点id
	Name       string   `gorm:"Name"`              // 名称
	Parent     *ObjectX `gorm:"foreignKey:ParentId;references:Id` // 关联查询父节点
查询语句是
var records []*ObjectX
err = db.Model(&ObjectX{}).Preload(clause.Associations).Scan(&records ).Error	
结果提示报错
 invalid field found for struct main.ObjectX's field Parent: define a valid foreign key for relations or implement the Valuer/Scanner interface  
我如何写这种自关联的结构呢？
