Answer 1

To import model instance and call method, for example

modelfile.js

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const NotificationSchema = new Schema({
    count: Number,
    color: String,
    icon: String,
    name: String,
    date: {type: Date, default: Date.now },
    read: Boolean
});

module.exports = mongoose.model('notifications', NotificationSchema);

queryfile.js

const Notification = require('./models/model-notifications');

function totalInsert(online) {
  let query = { name: 'viewed count' };
  Notification.find(query,(err,result)=>{
    if(!err){
      totalCount.count = online + result.length;
      totalCount.save((err,result)=>{
        if(!err){
          io.emit('total visitor', totalCount);
        }
      });
    }
  });
}

Make sure that you have exported your Model/Schema correctly.

module.exports = User

After this above step make sure to require the Model/Schema.js file in your index.js(Main Route File)

const Task = require('./models/task')

Below are some snippets for the explanation. All the best.!

i faced this issue . to solve this , you need to understand one logic . you need to call .find as promise to model which is imported from models file.

example:

const member = require('..// path to model')

//model initiation
const Member = new member();

exports.searchMembers = function (req,res) {


Member.find({},(err,docs)=>{
    res.status(200).json(docs)
})

}

this code dont work because i called find() to initiated schema

code that works :

exports.searchMembers = function (req,res) {


member.find({},(err,docs)=>{
    res.status(200).json(docs)
})

}

here i called .find() directly to imported model

Answer 4

Your module export is incorrect

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var listSchema = new Schema({
    name: { type: String, default: datestring + " List" }
});

**mongoose.exports = mongoose.model('List', listSchema);** <!-- this is wrong -->

it should be

**module.exports = mongoose.model('List', listSchema)**

Answer 5

You've defined incorrect module.exports.

mongoose.exports = mongoose.model('List', listSchema);

This should be

module.exports = mongoose.model("List", listSchema);
