Sails js,find user using either email or username - sails.js

Question

I am trying to login user using either username or email i.e user can enter either email or password and should be able to log in. However, so far I am able to use one of them.
Here is the code tried so far.
authenticate: function (req, res) {
var username = req.body.username;
var email = req.body.email;
users.findOne({
or: [
{username: username},
{email: email}
]
}).exec(function(err, user) {
console.log(user);
if (err) {
return res.json({err});
} else if (!user) {
var err = new Error('User not found.');
err.status = 401;
return res.json({err});
} else {
require('bcrypt').compare(req.body.password, user.password, function(err, result) {
if(result === true) {
return res.json({user});
} else {
return res.json({err});
}
});
}
});
}

Though sails waterline is not as powerful as direct access to any one db, it can do what you want here and much more. The docs give some good examples of what's possible.
I don't know exactly how you are passing in the username or email to your request object, but something like this should work:
authenticate: function(req, res) {
var username = req.param('username'); // or however you get this
var email = req.param('email'); // or however you get this
Users.findOne({
or: [{username: username}, {email: email}]
}).exec(function(err, user) {
// handle the error, or make use of found user...
});
}
You can also handle the case where user hands you an input that could be either a username or email...
var identifier = req.param('identifier'); // could be a username or an email
And then modify your or array to:
or: [{username: identifer}, {email: identifier}]
if you use the action 2 style, you can do
```
var identifier = inputs.identifier;
var userRecord = await User.findOne({
or : [{username: identifier}, {email: identifier}]
});
