Mongoose : Inserting JS object directly into db

Ok so I have a JS object that is being POSTed via AJAX to the nodejs backend. I want to insert this js object directly into my mongoose db as the object keys already match up perfectly with the db schema.

I currently have this (not dynamic and overly complex):

app.post('/items/submit/new-item', function(req, res){
    var formContents = req.body.formContents,
        itemModel = db.model('item'),
        newitem = new itemModel();

    newitem.item_ID    开发者_开发技巧     = "";
    newitem.item_title      = formContents.item_title;
    newitem.item_abv        = formContents.item_abv;
    newitem.item_desc       = formContents.item_desc;
    newitem.item_est        = formContents.item_est;
    newitem.item_origin     = formContents.item_origin;
    newitem.item_rating     = formContents.item_rating;
    newitem.item_dateAdded  = Date.now();

    newitem.save(function(err){
        if(err){ throw err; }
        console.log('saved');
    })

    res.send('item saved');
});

But want to trim it down to something like this (sexy and dynamic):

app.post('/items/submit/new-item', function(req, res){
    var formContents = req.body.formContents,

    formContents.save(function(err){
        if(err){ throw err; }
        console.log('saved');
    })

    res.send('item saved');
});

If you use a plugin like this with mongoose (http://tomblobaum.tumblr.com/post/10551728245/filter-strict-schema-plugin-for-mongoose-js) you can just put together an array in your form, like newitem[item_title] and newitem[item_abv] -- or item[title] and item[abv]

You could also just pass the whole req.body if the elements match up there. That MongooseStrict plugin will filter out any values not explicitly set in your schema, but it still leaves checking types and validation up to mongoose. With proper validation methods set in your schema, you will be safe from any injection attacks.

EDIT: Assuming you have implemented the plugin, you should be able to use this code.

app.post('/items/submit/new-item', function(req, res){
  new itemModel(req.body.formContents).save(function (e) {
    res.send('item saved');
  });
});
