Loopback：嵌套关系，在查询中获取父级

Question

所以我有这个场景

型号： - 竞赛 - 比赛赛季 - 匹配

比赛赛季在哪里：

  "relations": {
    "matches": {
      "type": "hasMany",
      "model": "match",
      "foreignKey": "competition-seasonId"
    },
    "competition": {
      "type": "belongsTo",
      "model": "competition",
      "foreignKey": ""
    }
  }

并且匹配有：

"relations": {
    "competition-season": {
      "type": "belongsTo",
      "model": "competition-season",
      "foreignKey": ""
    }
}

我要做的是在列出比赛时获取比赛对象，但是这样做

{
  include: ['competition-season']
}

现在我只是

[
  {
    id: 'xxxx',
    competition-seasonId: 'yyyy',
    competition-season: {
      competitionId: 'zzzz'
    }
  }
]

所以想得到比赛对象，而不仅仅是id

Answer 1

我自己想出来的！

include: [
  {
    relation: 'competition-season',
    scope: {
      include: 'competition'
    }
  }
]
