使用node express从mongodb检索数据

Question

在我的mongodb数据库中有4个集合。我可以使用每个集合逐个检索数据。现在，如何使用findone、getAll这样的关键字从同一代码中的不同集合中检索数据？我的模特。js如下所示。分贝-

模型1。js

const Schema=mongoose.Schema;
const customerSchema = new Schema({

    shop:{
        type : String,
        required : true,
    },
    name:{
        type : String,
        required : true,
    },

    area:{
        type : String,
        required : true,
    },
       {
    timestamps : true
    }
);
const Customer = mongoose.model('customers',customerSchema);
module.exports = Customer;

模式2。js

const mongoose = require('mongoose');

const Schema=mongoose.Schema;
const distributorSchema = new Schema({


    fullName:{
        type : String,
        required : true,
    },
    warehouse:{
        type : String,
        required : true,
    },
   phoneNo:{
        type : String,
        required : true,
    },

    password:{
        type : String,
        required : true
    }
},
    {
    timestamps : true
    }
);
const Distributor = mongoose.model('distributors',distributorSchema);
module.exports = Distributor;

您可以在控制器中创建函数。像这样

export async function getDataFromTwoCollections(){

  let allData = {modelOneData : [], modelTwoData : []};
  let modelOneData = await Customer.find({}).exec();
  let modelTwoData = await Distributor.find({}).exec();
  allData.modelOneData = modelOneData 
  allData.modelTwoData  = modelOneData
  return allData
}
