how to resolve error in sub documents mongoose/express -

-

i developing web application based on mean stack, have care add , edit operations, particularly sub documents of field "order", console tells me "reference" undefined on line "order.reference" : req.body.order.reference, , don't know how sub documents. when add or modify of "order" fields got error, when add fields without exception works. here mongoose diagram:

var mongoose = require('mongoose') , schema = mongoose.schema;  var contactschema = new schema({   name: {type: string},   order: {     reference : {type : string},     adresse : {type : string} ,     product : {type : string}   } });  var contactmodel = mongoose.model('contact', contactschema);  mongoose.connect('mongodb://localhost/contact');  exports.add = function(req, res) {     var contact = req.body;     contact = new contactmodel({       name: req.body.name,             "order.reference" : req.body.order.reference,       "order.adresse" : req.body.order.adresse,       "order.product" : req.body.order.product     });      contact.save(function (err) {       if (!err) {         res.json(true);       } else {         console.log(err);         res.json(false);       }     });     return res.jsonp(req.body); };  exports.edit = function (req, res) {   var id = req.params.id;   if (id) {     contactmodel.findbyid(id, { upsert: true }, function (err, contact) {        contact.name = req.body.name,       contact.order.reference = req.body.order.reference,       contact.order.adresse = req.body.order.adresse ,       contact.order.product = req.body.order.product           contact.save(function (err) {         if (!err) {           res.json(true);         } else {           res.json(false);           console.log(err);         }       });      });   } };

thank time, can provide angular code , html

you'll want use express , body parser: how extract post data in node.js?

note: believe written express 3 , syntax little different express 4
