    "__v" : 0
}

Мне нужно найти одного из сотрудников из массива company.shops.staffs по _id, и я также хочу включить все доступные магазины от компании довыходной документ.

Вот агрегация, которую я пробую:

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});
                }
            });

, но это всего лишь магазин сотрудников, где работают.

Как я могу генерировать oputputdoc, как этот?:

{"staff":<staffData>,"shops":[shopsArray]}

////// EDITED ////// Поэтому мне нужно найти сотрудников из массива shops.staff и всех магазинов из массива company.shopsи поместите его в документ следующим образом:

{
    "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>]
}

Надеюсь, теперь все ясно, спасибо!

Попробуйте это

Я использовал map и filter

db.companyManager.aggregate([
    {
        '$addFields': {
            'staff': {
                '$filter': {
                    'input': {
                        '$map': {
                            'input': '$shops', 
                            'as': 'shop', 
                            'in': {
                                'staffs': {
                                    '$filter': {
                                        'input': '$$shop.staffs', 
                                        'as': 'staff', 
                                        'cond': {
                                            '$eq': [
                                                '$$staff._id', body.staffId
                                            ]
                                        }
                                    }
                                }

                    }, 
                    'as': 'staff', 
                    'cond': {
                        '$gt': [
                            {
                                '$size': '$$staff.staffs'
                            }, 0
                        ]
                    }
                }
            }
        }
    },
    {$unwind: "$staff"},
    {$project:  {_id:0, staff: "$staff.staffs", shops: "$shops"} },
    {$unwind: "$staff"}
])
