我有文件，比如这个：

我必须通过 _id 从 company.shops.staffs 数组中找到一名员工，并且我还想将公司中所有可用的商店包含到输出文档中。
这是我尝试的聚合：
this.companyManager.aggregate([
{"$match": {"shops.staffs._id": body.staffId}},
{"$unwind": "$shops"},
{"$unwind": "$shops.staffs"},
{"$match": {"shops.staffs._id": body.staffId}},
{"$project": {_id: "$shops.staffs._id", shops: "$shops", staff: "$staffs"}},
], function(error, result:Null<Array<Dynamic>>) {
trace(error);
trace(result);
if (result.length == 0) {
callback({status: Status.ERROR, data: result, error: "not found staff"});
} else {
callback({status: (error == null) ? Status.SUCCESS : Status.ERROR, data: result[0].staff, error: error});
}
});
但这只是包括工作人员所在的商店。
如何生成像这样的输出文档？：
{"staff":<staffData>,"shops":[shopsArray]}
//////已编辑////// 所以我需要从 shop.staff 数组中找到一个员工，并从 company.shops 数组中找到所有商店，并将其放入文档中，如下所示：
{
"staff": {
"permissions": [
"staffServing"
],
"_id": ObjectId("5c7a6248b2e01c744f8b67b5"),
"email": "varadi83gabor@gmail.com",
"modifyed": null,
"name": "12e12e",
"nickname": "qweqwe",
"password": "202cb962ac59075b964b07152d234b70",
"registered": ISODate("2019-03-02T11:00:25.956Z"),
"status": "active"
},
"shops": [<SHOPS DOCUMENTS>]
}
我希望现在已经清楚了，谢谢！
【问题讨论】：

真的不太清楚你想在这里做什么。您是否可能试图获取一个人（或多个人）工作的“所有商店”的所有详细信息？按原样分组“每人”？然后你会想要所有的细节吗？即包括在每个商店工作的所有其他人。
"$staffs"甚至不是一个有效的字段并没有真正的帮助，所以甚至不清楚你期望你当前的代码产生什么。 -
我想通过 id: (done) 找到一名员工，并包括公司内所有可用的商店。我需要这个来将选定的员工转移到另一家商店。

您能否在edit your question 提供更多详细信息，然后发表评论以通知您何时完成。这比试图在 cmets 中写一个长篇故事（或呈现数据）要好。
