Regarding pull request #84 ( alternative fields for login)

[deveshsinghal22]

i have added the new field for usernameQueryFields

UserSchema.plugin(passportLocalMongoose,{
        'usernameField' : 'mobile',
        'usernameQueryFields' : ['email']
    }
);

This is working fine for login but at the time of signup using the above config it is throwing error
BadRequestError: Field mobile is not set when i pass the {email : '[email protected]'} in user. register function.

In my application flow, user have only 2 fields in signup form. one for email/mobile and another for password. if user enter a email then it goes to the email field of userSchema otherwise it goes to mobile field.

I was asking for something like this

    schema.statics.register = function(user, password, cb) {
        // Create an instance of this in case user isn't already an instance
        if (!(user instanceof this)) {
            user = new this(user);
        }

        // check each username query field
        var usernameFieldFound = false,
            usernameField;
        for (var i = 0; i < options.usernameQueryFields.length && !usernameFieldFound; i++) {
            if (user.get(options.usernameQueryFields[i])) {
                usernameField = options.usernameQueryFields[i];
                usernameFieldFound = true;
            }
        }

        if(!usernameFieldFound) {
            //@todo need to refactor this
            return cb(new BadRequestError(util.format(options.missingUsernameError, options.usernameField)));
        }

        /*if (!user.get(options.usernameField)) {
            return cb(new BadRequestError(util.format(options.missingUsernameError, options.usernameField)));
        }*/

        var self = this;
        self.findByUsername(user.get(usernameField), function(err, existingUser) {
            if (err) { return cb(err); }

            if (existingUser) {
                return cb(new BadRequestError(util.format(options.userExistsError, options.usernameField, user.get(options.usernameField))));
            }
            user.setPassword(password, function(err, user) {
                if (err) {
                    return cb(err);
                }

                user.save(function(err) {
                    if (err) {
                        return cb(err);
                    }
                    cb(null, user);
                });
            });
        });
    };

I'm having the same issue. Looks like it works fine for the default 'username' field, but not for a custom field.

I'm using Passport-Local-Mongoose v1.2.0
