Question

我试图在一个旧项目上实现passsport，并且scema被设置为嵌套用于不同的东西，例如下面的名称模式是我的子模式。（还有更多这只是一个例子）

var nameSchema = new Schema(
{
    _id: false,
    "firstname"     : {type: String, required: true},
    "lastname"      : {type: String, required: true}
});

// Schema setup
var schema = new Schema(
{
    local       :
    {
        name        :   nameSchema,
        email       :   { type: String, required: true, trim: true, unique: true, select: true},
        password    :   { type: String, required: true, trim: true, select: true},
        regDate     :   { type: Date, select: false, createdAt: true},
        alevel      :   { type: Number, min : 1, max : 5, default: 1, select: true },

    }
});

但是当我把它添加到我的本地策略时，我得到一个错误TypeError: Cannot set property 'firstname' of undefined如何实现嵌套的json策略。目前我所拥有的是：

 passport.use('local-signup', new LocalStrategy({
        usernameField : 'email',
        passwordField : 'password',
        aLevelField   : 'aLevel',
        namefield   : {
            firstnameField  : 'firstname',
            lastnameField   : 'lastname' 
        },
        passReqToCallback : true 
}, 
function(req, email, password, done) {
    process.nextTick(function() {
        User.findOne({ 'local.email' :  email }, function(err, user) {
            if (err){
                return done(err);
            }
            if (user){
                return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
            } else {
                var user = new User();
                user.local.email = email;
                user.local.password = password;
                user.local.aLevel = req.body.aLevel;
                user.local.name.firstname = req.body.firstname; // <-- error
                user.local.name.lastname = req.body.lastname;
                console.log('after define',user);

                user.save(function(err){
                    if (err){
                        console.log(err)
                        throw err;
                    }
                    return done(null, user);
                });
            }
        });    
    });

}));

只是因为任何人都会碰到这个并且无法弄明白。当我打电话给 user.local.name.firstname = req.body.firstname我可以假设这是试图访问.name.firstname，但因为它是空的，所以也没有设置.firstname。要解决它：

user.local.name = { firstname : req.body.firstname, lastname : req.body.lastname };

PassPortjs设置本地注册以使用嵌套的json
