使用Express和Mongoose将表单数据发送到现有MongoDB文档的数组

Question

我试图创建一个Mongo文档，然后更新文档表单，使其具有附加属性，其中一个属性有一个对象数组。

var UserSchema = new mongoose.Schema({
     username: { type: String, lowercase: true }
    , password: { type: String }
    , email: { type: String, lowercase: true }
    , phone: { type: String }
    , newsletter: Boolean
    , created: { type: Date, default:   Date.now }
    , address: [{
        nickname: { type: String }
        , streetAddress: { type: String }
        , streetAddress2: { type: String }
        , state: { type: String }
        , zip: { type: String }
    }]    
});

module.exports = exports = function(){
    //create account
    this.createAndSave = function (req, res ) {
        new User({
            username: req.body.username
            , password: req.body.password
            , email: req.body.email
            , phone: req.body.phone
            , address: [{
               nickname: req.body.nickname
               , streetAddress: req.body.streetAddress
               , streetAddress2: req.body.streetAddress2
               , state: req.body.state
               , zip: req.body.zip
            }]
        }).save(function (err, user){
            if (err) throw err;
            req.session.isLoggedIn = true;
            req.session.user = user.username;
            res.redirect('/account/' + user.username)
        })
    }

//update account
this.updateRequest = function (req, res) {
    User.update({username: req.user.username}, {
        username: req.body.username
        , email: req.body.email
        , phone: req.body.phone
        , newsletter: req.body.newsletter
        , address: [{
           nickname: req.body.nickname
           , streetAddress: req.body.streetAddress
           , streetAddress2: req.body.streetAddress2
           , state: req.body.state
           , zip: req.body.zip
        }]
      }, function (err) {
        res.redirect("/account/" + req.body.username);
    });
}

h1 Edit User
#{user}
form(method="POST", action="/account/#{user.username}")
    input(type="hidden", name="_method", value="PUT")
    .form-group
        label(for="username") Name
        input#name.form-control(type="text", name="username", value= user.username )

    .form-group
        label(for="email") Email
        input#email.form-control(type="email", name="email", value= user.email )

        input#phone.form-control(type="text", name="phone", value= user.phone )

        input#newsletter(type="checkbox", name="newsletter", checked=(true===false ? "checked" : undefined))

    if(user.address.length > 0)
            for (var i = 0; i < user.shippingAddresses.length; i++) {}>)
                .form-group
                    label Street Address
                    input#address.form-control(type="text", name="streetAddress", value= user.shippingAddresses[i].streetAddress )

                .form-group
                    label Address Continued
                    input#address2.form-control(type="text", name="streetAddress2", value= user.shippingAddresses[i].streetAddress2 )

                .form-group
                    label Zip Code
                    input#zip.form-control(type="text", name="zip", value= user.shippingAddresses[i].zip )
    else
                .form-group
                    label Location Nick Name
                    input#address.form-control(type="text", name="nickname", value= )

                .form-group
                    label Street Address
                    input#address.form-control(type="text", name="streetAddress", value= )

                .form-group
                    label Address Cont.
                    input#address2.form-control(type="text", name="streetAddress2", value= )
                .form-group
                    label State
                    input#state.form-control(type="text", name="state", value= )
                .form-group
                    label Zip Code
                    input#zip.form-control(type="text", name="zip", value= )


    button(type="submit") Update Account

另外需要注意的是，我无法从更新函数中获得任何更新的数据来保存到Mongo。

谢了！

这是我想出的解决办法。我找到要更新的文档，并将一个对象推送到存储数组的属性。

示例方法：

this.addAddress = function (req, res) {
    var newAddress = {
           nickname: req.body.nickname,
           streetAddress: req.body.streetAddress,
           streetAddress2: req.body.streetAddress2,
           state: req.body.state,
           zip: req.body.zip
    }
    User.update({username: req.session.user}, { $push : {
            address: newAddress
        }}, {upsert: true}, function ( err ) {
                if(err){
                        console.log(err);
                }else{
                        console.log("Successfully added");
                }
        })
}
