Where to find Mongo Collection in Express? - mongodb

Question

I'm reviewing some old code I wrote in Express/Mongo/Mongoose (based on an online tutorial) and can't locate the portion of code which dictates which Collection in MongoDB gets written to.
I have a Database, UsersDB and within that database there are several Collections. The Collection that keeps growing every time the code executes user.save is the users Collection. But I can't find any reference in my code base to the users collection.
The only place in my code where I save a User is:
var app = require('../app');
var util = require('util');
var User = require('../models/user'),
Auth = User.Auth,
Name = User.Name,
Email= User.Email,
Phone = User.Phone,
Address = User.Address,
Company = User.Company,
PersonalData = User.PersonalData,
Id = User.Id,
Photo = User.Photo,
Member = User.Member,
CreditCard = User.CreditCard,
UserObj = User.User;
var moment = require('moment');
var async = require('async');
. . .
. . .
exports.user_create_post = [
(req,res, next) => {
console.log("Request: " + util.inspect(req.body));
},
//VALIDATE
body('mainEmail', 'Must be valid email.').isLength({min: 5}).trim(),
//SANITIZE
sanitizeBody('*').escape(),
//POPULATE NEW DOCUMENT
(req,res,next) => {
const errors = validationResult(req);
var auth = new Auth(
dateEffective: {value: moment(Date.now()).format("YYYY-MM-DD hh:mm:ss SSS"), attr: {hidden: true, label: ""}},
username: {"value": req.body.username, "attr": {hidden: false, label: "Username: "}},
password: {"value": req.body.password, "attr": {hidden: false, label: "Password: "}},
mainEmail: {"value": req.body.mainEmail, "attr": {hidden: false, label: "Email: "}}
});
var user = new UserObj(
{authData: [auth]}
);
if (!errors.isEmpty()) {
const errorFormatter = ({ location, msg, param, value, nestedErrors }) => {
// Build your resulting errors however you want! String, object, whatever - it works!
return `${location}[${param}]: ${msg}`;
};
const result = validationResult(req).formatWith(errorFormatter);
if (!result.isEmpty()) {
return res.json({ errors: result.array() });
}
}
else {
user.save(function(err){
if (err) { return next(err);}
});
res.redirect("http://localhost:4200/two-fa/"+user._id);
}
}
I also have a Models module (user.js):
. . .
. . .
. . .
module.exports = {
Auth: mongoose.model('Auth', AuthSchema),
Name: mongoose.model('Name', NameSchema),
Email: mongoose.model('Email', EmailSchema),
Phone: mongoose.model('Phone', PhoneSchema),
Address: mongoose.model('Address', AddressSchema),
Company: mongoose.model('Company', CompanySchema),
PersonalData: mongoose.model('PersonalData', PersonalDataSchema),
Id: mongoose.model('Id', IdSchema),
Photo: mongoose.model('Photo', PhoneSchema),
Member: mongoose.model('Member', MemberSchema),
CreditCard: mongoose.model('CreditCard', CreditCardSchema),
User: mongoose.model('User', UserSchema)
}
I did a search on my entire code, and nowhere is there any mention of users, which is the Collection that's getting written to.
Where should I look to try to trace how the users collection is getting written to?
Thank you!

As per how-to-access-a-preexisting-collection-with-mongoose, if a 3rd argument to mongoose.model is not provided, then Mongo automatically "pluralizes" the model name to give the name of the Collection.
