Go 中的切片指针与 GAE Datastore 是否有良好的“关系”？

Question

根据App Engine 文档中的祖先查询，我可以执行以下操作：

type Team struct {

    Name string

}

type Player struct {

    Name string

}

// Save data first just for the test case

teamA := datastore.NewIncompleteKey(c, "Team", nil)

teamA, _ = datastore.Put(c, teamA, Team{"Team A"})

playerA := datastore.NewIncompleteKey(c, "Player", teamA)

playerA, _ = datastore.Put(c, playerA, Player{"Player A"})

playerB := datastore.NewIncompleteKey(c, "Player", teamA)

playerB , _ = datastore.Put(c, playerB, Player{"Player B"})

// query data

q := datastore.NewQuery("Team").Filter("Name=", "Team A").Limit(1).KeysOnly()

teams, _ := q.GetAll(c, nil)

q = datastore.NewQuery("Player").Ancestor(teams[0])

var players []Player

q.GetAll(c, &players)

但是......如果我想让 Team 包含一个指向玩家切片的指针，那么我会将它保存为 nil，当我查询它时，我会分配它，有点像这样：

type Team struct {

    Name string

    Players *[]Player `datastore:-`

}

type Player {

    Name string

}

// Save data first just for the test case

teamA := datastore.NewIncompleteKey(c, "Team", nil)

teamA, _ = datastore.Put(c, teamA, Team{"Team A", nil})

/* Saving player data goes here */

// query data

q := datastore.NewQuery("Team").Filter("Name=", "Team A").Limit(1)

var teams []Team

teamKeys, _ := q.GetAll(c, teams)

q = datastore.NewQuery("Player").Ancestor(teamKeys[0])

q.GetAll(c, teams[0].Players)

这是模拟关系的好方法吗？

对于我的应用程序，树状结构将是完美适合我手指的戒指。

或者……你还有什么建议吗？
