Existing property return undefined

I started the implementation of a RESTful API usin node.js, express, and mongodb. Everything went well until now, I've a route to authenticate an user as follow:

apiRoutes.post('/authenticate', function(req, res) {
    User.findOne({
        nickname: req.body.nickname
    }, function(err, user) {

        if (err) throw err;

        if (!user) {
            res.json({
                success: false,
                message: 'Authentication failed. User not found.'
            });
        } else if (user) {
            console.log(user);
            console.log(user.nickname);
            console.log(user.email);
            console.log(user.password);
            console.log(user.sexe);

            if (user.password != req.body.password) {
                res.json({
                    success: false,
                    message: 'Authentication failed. Wrong password.'
                });
            } else {
                var token = jwt.sign(user, app.get('salt'), {
                    expiresInMinutes: 1440 // expires in 24 hours
                });

                res.json({
                    success: true,
                    token: token
                });
            }
        }
    });
});

The user is retrieved, and loged in the console as follow:

{ sexe: 'H',
  email: '[email protected]',
  password: 'bambou',
  nickname: 'MrPanda',
  _id: 56cb703e7aef3f83c7dac0a7 }

which is perfect, but then, the three following consol.log return the three following lines:

MrPanda
[email protected]
undefined
H

I see absolutely no reason why the password is undefined at this point, I tried to change the attribute name to 'mdp', same issue... Any ideas ? Thanks

If you are using mongoose it does not return a plain JSON object. It is actually a special mongoose object and may not function how you expect.

You have two options:

  1. Convert the mongoose object to a JSON object.

    • Add {lean: true} to the Users options parameter.
    • OR JSON.stringify(user)
    • OR user.toJSON()

  2. Use the proper get() and set() methods (which you should be doing anyways).

    • user.get('password')
    • user.get('email')
    • user.get('name')

Try that and let me know if it doesn't work still.
