聚合mongoDB集合：通过第一个集合（映射），每个键都指向另一个集合ID

Question

我仍然有一个 mongod noSQL ，如下所示：

db.bynder_jobs.aggregate([
  { $match: { campaignID: { $eq: "12087c22-260a-4fb8-834e-d231c4c277a3" } } },
  {
    $lookup: {
      localField: "presetID",
      from: "job_presets",
      foreignField: "ID",
      as: "joincollection"
    }
  },
  {
    $lookup: {
      localField: "createdByID",
      from: "users",
      foreignField: "ID",
      as: "joincollection2"
    }
  },
  {
    $lookup: {
      localField: "campaignID",
      from: "campaign",
      foreignField: "ID",
      as: "joincollection3"
    }
  },
  {
    $lookup: {
      localField: "campaignID",
      from: "campaign",
      foreignField: "ID",
      as: "joincollection3"
    }
  }
  //{"$lookup":{"localField":"jobMetaproperties","from":"campaign","foreignField":"ID","as":"joincollection3"}}
]);

我还有一个集合（AllMetaData），所以我想映射所有bynder_jobs。 jobMetaproperties（array）键指向AllMetaData id，并获取AllMetaData.lavel接受所有jobMetaproperties键。
