объединение данных для 3 моделей с использованием mon goose, node js, express js

Question

Я хочу связать 3 модели "перевод * ca * 1022", "реквизиты субсчета", "банковские депозиты". То, что я хочу сделать, это то, что эти три имеют общий получить требуемый "Current_balance" «Current_balance» должен быть обновлен в 3 моделях, связав их. Это моя схема и контроллеры

BankdepositModel. js

var mongoose = require("mongoose");

var BankDepositsSchema = new mongoose.Schema(
  {
    source_sub_account: Array,
    amount: Number,
    cheque_notes: Number,
    to_bank_account: Array,
    amount_in_words: String,
    bank_Ref_no: String
  },
  {
    timestamps: true
  }
);

module.exports = mongoose.model("BankDeposits", BankDepositsSchema);

Subaccountdetailsmodel. js

var mongoose = require("mongoose");

var SubAccountDetailsSchema = new mongoose.Schema(
  {
    sub_account_name: String,
    current_balance: Number,
    account: Array
  },
  {
    timestamps: true
  }
);

module.exports = mongoose.model("SubAccountDetails", SubAccountDetailsSchema);

cashtransfermodel. js

var mongoose = require('mongoose');
var CashTransferSchema = new mongoose.Schema 
    ({
        source_sub_account:Array,
        description:String,
        recieved_by:String,
        amount:Number,
        date_time_transferred:Date,
        destination_sub_account:Array,
        amount_in_words:String,
            },
    {
        timestamps:true
    });
module.exports =mongoose.model('CashTransfer', CashTransferSchema);

Контроллер. js

var BankDeposits = require("../model/bankdepositmodel");

  BankDeposit.save()
    .then(data1 => {
      res.send(data1);
    })
    .catch(err => {

    });
};

//BankDeposit get

        foreignField: "current_balance",
        as: "balance"
      }
    }
  ])
    .then(appdata => {
      res.status(200).send(appdata); //On successful fetch, server responds with status 200
    })
    .catch(err => {

      });
    });
};

//CashTransfers Post Request
exports.create5 = (req, res) => {

 var Cash = new CashTransfer
