我能夠通過這種情況部分解決這個問題不幸的是，Preload() 函數似乎不適用于深入研究相關對象集。為了澄清，我有以下模型：    type Room struct {        gorm.Model        Name    string        Games   []Game `gorm:"ForeignKey:RoomID"`    }    type Game struct {        gorm.Model        RoomID   int `gorm:"index"`        Players  []Player `gorm:"ForeignKey:GameID"`    }    type Player struct {        gorm.Model        Name   string        GameID int `gorm:"index"`    }當我創建一個包含新房間、游戲和玩家對象的新對象時，我會返回以下數據（json 編碼）：    {"Value":{"ID":26,"CreatedAt":"2016-05-15T01:21:22.426234189-07:00","UpdatedAt":"2016-05-15T01:21:22.426234189-07:00","DeletedAt":null,"Name":"foo","Games":[{"ID":17,"CreatedAt":"2016-05-15T01:21:22.427026134-07:00","UpdatedAt":"2016-05-15T01:21:22.427026134-07:00","DeletedAt":null,"RoomID":26,"Turns":null,"Players":[{"ID":4,"CreatedAt":"2016-05-15T01:21:22.427560561-07:00","UpdatedAt":"2016-05-15T01:21:22.427560561-07:00","DeletedAt":null,"Name":"TestPlayer","GameID":17}],"Counter":1,"Assigned":false}],"Testing":false},"Error":null,"RowsAffected":1}但是，如果我嘗試使用 preload() 函數查詢結構，我會得到以下信息：    {"Value":{"ID":26,"CreatedAt":"2016-05-15T01:21:22.426234189-07:00","UpdatedAt":"2016-05-15T01:21:22.426234189-07:00","DeletedAt":null,"Name":"foo","Games":[{"ID":17,"CreatedAt":"2016-05-15T01:21:22.427026134-07:00","UpdatedAt":"2016-05-15T01:21:22.427026134-07:00","DeletedAt":null,"RoomID":26,"Turns":null,"Players":null,"Counter":1,"Assigned":false}],"Testing":false},"Error":null,"RowsAffected":1}請注意，Players 部分現在為空。這是我的房間注冊和房間查詢功能：    func RegisterRoom(w http.ResponseWriter, r *http.Request) {        err := r.ParseForm()        if err != nil {            // Handle error        }
