hello I am just new in learning about mongo db and node js
but actually I am facing a very bad error
like this is my router users.js
var express = require('express');
var router = express.Router();
const { check, validationResult } = require('express-validator');
const User = require('../models/User');
const passport = require('passport');
/* GET users listing. */
router.get('/signup', function (req, res, next) {
var massagesError = req.flash('error')
res.render('signup', { massages: massagesError })
});
router.post('/signup', [
check('name').not().isEmpty().withMessage('Please Enter Your Name'),
check('email').not().isEmpty().withMessage('Please Enter Your Email'),
check('email').isEmail().withMessage('Please Enter Valid Email'),
check('password').not().isEmpty().withMessage('Please Enter your Password'),
check('password').isLength({ min: 8 }).withMessage('Please Enter Password more than 8 characters'),
check('confirm-password').custom((value, { req }) => {
if (value !== req.body.password) {
throw new Error('Password and confirm-password do not match');
}
return true;
}),
check('phoneNumber').not().isEmpty().withMessage('Please Enter your Phone Number'),
check('phoneNumber').isMobilePhone().withMessage('please enter Valid Phone Numeber'),
check('userType').isIn(['sponsor', 'student']).withMessage('Please select a valid user type')
], (req, res, next) => {
const errors = validationResult(req);
if (!errors.isEmpty()) {
var validationMassages = [];
for (var i = 0; i < errors.errors.length; i++) {
validationMassages.push(errors.errors[i].msg)
}
req.flash('error', validationMassages);
res.redirect('signup')
console.log(validationMassages);
return;
}
const user = new User({
name: req.body.name,
email: req.body.email,
password: new User().hashPassword(req.body.password),
phoneNumber: req.body.phoneNumber,
userType: req.body.userType
})
User.findOne({ email: req.body.email })
.then(result => {
if (result) {
// User with the provided email already exists
req.flash('error', 'this email already exist')
res.redirect('signup')
return;
}
user.save()
.then(doc => {
res.send(doc);
})
.catch(error => {
console.log(error);
res.status(500).send('An error occurred while saving the user');
})
})
})
router.get('/profile', (req, res, next) => {
res.render('profile')
});
router.get('/signin', (req, res, next) => {
res.render('signin');
})
router.post('/signin', passport.authenticate('local-signin',
{session:false,
successRedirect: 'profile',
failureRedirect: 'signin',
failureFlash : true,
}))
module.exports = router;
and this is my passport file passport.js
const passport = require('passport');
const localStrategy = require('passport-local').Strategy;
const User = require('../models/User');
passport.use('local-signin', new localStrategy({
usernameField: 'email', // default is username, override to accept email
passwordField: 'password',
passReqToCallback: true // allows us to access req in the call back
}, async (req, email, password, done) => {
// Check if user and password is valid
let user = await User.findBy('email', email)
let passwordValid = user && bcrypt.compareSync(password, user.passwordHash)
// If password valid call done and serialize user.id to req.user property
if (passwordValid) {
return done(null, {
id: user.id
})
}
// If invalid call done with false and flash message
return done(null, false, {
message: 'Invalid email and/or password'
});
}))
every time I try to signin with already existing user in the database the system alwasy redirect me to the failurRedirect even if it correct
