gorm golang有两张相同的桌子吗

我正在尝试使用golang gorm在（我的）sql表中创建一个自引用。目前，我的代码如下所示：

type Person struct {
    gorm.Model
    Name string
    Children []*Person `gorm:"ForeignKey:ParentID"`
    ParentID uint
}

func main() {
    /* code to get database connection omitted */

    p := &Person{Name:"Sally"}
    db.Create(p)

    children := []*Person{ {Name:"Jane", ParentID:p.ID},
        {Name:"Tom", ParentID:p.ID}}

    for _, child := range children {
        db.Create(child)
    }

    var children2 []*Person

    db.Model(p).Related(children2, "ParentID")
}

type Person struct {
  gorm.Model
  Name string
  Children []*Person `gorm:"many2many: children;association_jointable_foreignkey:children_id"`
}

代码失败，出现错误“reflect.Value.Set using unaddressable Value”

有人知道如何使用go gorm来维持这种关系吗

非常感谢：）

幸运的是，gorm最近添加了此功能（参考：）

在您的情况下，应该是这样的：

type Person struct {
    gorm.Model
    Name string
    Children []*Person `gorm:"ForeignKey:ParentID"`
    ParentID uint
}

func main() {
    /* code to get database connection omitted */

    p := &Person{Name:"Sally"}
    db.Create(p)

    children := []*Person{ {Name:"Jane", ParentID:p.ID},
        {Name:"Tom", ParentID:p.ID}}

    for _, child := range children {
        db.Create(child)
    }

    var children2 []*Person

    db.Model(p).Related(children2, "ParentID")
}

type Person struct {
  gorm.Model
  Name string
  Children []*Person `gorm:"many2many: children;association_jointable_foreignkey:children_id"`
}
