How to change collection name in mongoose.model? - node.js

Question

Am new in Nodejs, Am trying to create user login system with mongoDB and passportjs. Here i want to change collection name.
i refer this video here
This is my code:
Database connection js
config/database.js
module.exports = {
database : 'mongodb://localhost:27017/my_first_project',
secret : 'Mysecret'
}
models/admin.js
const mongoose = require('mongoose');
let AdminSchema = mongoose.Schema({
name:{
type: String,
required: true
},
email:{
type: String,
required: true
},
username:{
type: String,
required: true
},
password:{
type: String,
required: true
},
created_on:{
type: Date,
default: Date.now
},
status:{
type: Number,
required: true,
validate : {
validator : Number.isInteger,
message : '{VALUE} is not an integer value'
}
}
});
const Admin = module.exports = mongoose.model('User', AdminSchema);
config/passport.js
const LocalStorage = require('passport-local').Strategy;
const User = require('../models/admin');
const config = require('../config/database');
const bcrypt = require('bcryptjs');
module.exports = function(passport){
//Local Strategy
passport.use(new LocalStorage(function(username, password, done){
//Check username
let query = {username:username};
console.log(query);
User.findOne(query, function(err, user){
console.log(user);
if(err) throw err;
if(!user)
{
return done(null, false, {message: 'No user found'});
}
//check password
bcrypt.compare(password, user.password, function(err, isMatch){
if(err) throw err;
if(isMatch){
return done(null, user);
}else{
return done(null, false, {message: 'Wrong password'});
}
});
});
}));
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
}
This is my database structure
When i user correct username and password for login passportjs shows null.
Need to change collection name as admin.
I don't know how to ask this question. If am asking wrong sorry for all.

You can use this structure.
API structure of mongoose.model is this:
Mongoose#model(name, [schema], [collection], [skipInit])
which means
mongoose.model('User', AdminSchema, 'admin');
//Here 3rd argument 'admin': as collection name
You can do with this too
let AdminSchema = mongoose.Schema({
username : String,
password : String.
.......
}, { collection: 'admin' });
See this link from the Mongoose documentation.
