Model.find is not a function in mongoose

I am new in node and mongodb. I am trying to query a different model(Event) from another model(Company).

Basically in Event model there is a field called company. I would like to get the company where id is an Event ID.

I have all the event IDs in an array.

 let eventIds = [ 5b76a8139dc71a4a12564cd2,
  5b9a1685c239342d4635466c,
  5b8e753bdbccf803e906aaeb ]

Event Schema --

var EventSchema = new Schema({
        title:{type:String,require:true,index:true},
        description:{type:String,require:false},
        companies:[
            {type:Schema.Types.ObjectId,ref:"Company",require:true,index:true}
        ]
});

In company model --

var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    Event = require('./event.js');

var CompanySchema = new Schema({
        name:{type:String,require:true,index:true},
        description:{type:String,require:false}},{
        //no auto indexing at the beginning
        autoIndex:true,

        //no strict to save changes in the valuesBeforeChange field.
        strict:false}
);

CompanySchema.static("searchCompanies",function(callback,criteria){

    "use strict";
    var That = this;
    var query = That.find();

    async.waterfall([

         function(callback){
             let eventIds =  [5b76a8139dc71a4a12564cd2,5b9a1685c239342d4635466c,5b8e753bdbccf803e906aaeb ];
             Event.find({ $in: eventIds}, function(err, docs){
                   console.log(docs);
             });
     }

],function(err,companyResultObj){
         callback(err,companyResultObj);
    });
});

I am getting Event.find is not a function error message. How can I query a different model(event) from another model(company)

Any help is highly appreciated.

If you're importing your model from an index.js or index.ts file, you had better import the file as:

import YourModel from "./<file>/index"

This worked for me:

In my project I pass a Model into some middleware and started seeing this issue so I used mongoose.model('Name of Model')

example: .get(advancedResults(mongoose.model('Store'), 'stores'), getStores)

Not sure why but I had to do this in the following way.

Event.find({ $in: eventIds}, function(err, docs){

To

mongoose.model('Event').find({_id:eventIds}, function(err, docs){

which returned 3 documents which are correct.

How are you exporting your EventModel? Assuming you are exporting it like as a module (module.exports = { EventModel }), you want to go "const Event = require('./event.js').EventModel;"

Then simply go with "Event.find(..."

Use alias when you require file

EventModel = require('./event.js');
then 
EventModel.find({ $in: eventIds}, function(err, docs){
   console.log(docs);
});
