javascript - Can't update object in database -

i'm trying update array in 1 of database objects.

i'm checking object before making put request. object won't update in mongodb database.

client/entry/newentry.controller.js:

$scope.save = function(form) {     $scope.submitted = true;     $scope.entry.date = date.now;     $scope.entry.writer = $scope.getcurrentuser;     $scope.entry.type = 'chapter';     gethighestarticleid();     $scope.entry.articleid = articleid;      if(form.$valid) {       $http.post('/api/entrys', $scope.entry)         .success(function(data){           console.log(' -- posted entry --');           console.log('data: ', data);           $scope.entry = data;            console.log($scope.entry.orphan);           if($scope.entry.orphan == false){               $scope.parent.children.push($scope.entry);                console.log(' -- parent update --');               console.log($scope.parent);                $http.put('/api/entrys/' + $scope.parent._id)                 .success(function(data){                   console.log(' -- updated parent --');                   console.log(data);                 });           }         });     } }; 

entry api/entry/index.js:

'use strict';  var express = require('express'); var controller = require('./entry.controller');  var router = express.router();  router.get('/', controller.index); router.get('/:id', controller.show); router.get('/:id/children/', controller.getchildren); router.get('/type/:type', controller.getbytype); router.get('/type/:type/orphan/:hasparent', controller.getbytypeandorphan); router.post('/', controller.create); router.put('/:id', controller.update); router.patch('/:id', controller.update); router.delete('/:id', controller.destroy);  module.exports = router; 

api/entry/entry.controller.js:

// updates existing entry in db. exports.update = function(req, res) {   if(req.body._id) {        delete req.body._id;    }   entry.findbyid(req.params.id, function (err, entry) {     if (err) {          return handleerror(res, err);      }      if(!entry) {          return res.send(404);      }      var updated = _.merge(entry, req.body);      updated.save(function (err) {       if (err) {            return handleerror(res, err);        }       return res.json(200, entry);     });   }); };

edit

routes.js:

/**  * main application routes  */  'use strict';  var errors = require('./components/errors');  module.exports = function(app) {    // insert routes below   app.use('/api/languages', require('./api/language'));   app.use('/api/forums', require('./api/forum'));   app.use('/api/entrys', require('./api/entry'));   app.use('/api/things', require('./api/thing'));   app.use('/api/users', require('./api/user'));    app.use('/auth', require('./auth'));    // undefined asset or api routes should return 404   app.route('/:url(api|auth|components|app|bower_components|assets)/*')    .get(errors[404]);    // other routes should redirect index.html   app.route('/*')     .get(function(req, res) {       res.sendfile(app.get('apppath') + '/index.html');     }); }; 

found answer. problem in 3 places. first in call api

$http.put('/api/entrys/' + $scope.parent._id)    .success(function(data){       console.log(' -- updated parent --');       console.log(data); }); 

should instead be

$http.put('/api/entrys/' + $scope.parent._id, $scope.parent)    .success(function(data){       console.log(' -- updated parent --');       console.log(data); }); 

the second problem child object. passed entire object, needed id, push should change this

$scope.parent.children.push($scope.entry); 

to this

$scope.parent.children.push($scope.entry._id); 

finally update function needed informed handling sub-document. meant had add function

// updates existing entry in db. exports.update = function(req, res) {   if(req.body._id) {        delete req.body._id;    }   entry.findbyid(req.params.id, function (err, entry) {     if (err) {          return handleerror(res, err);      }      if(!entry) {          return res.send(404);      }      var updated = _.merge(entry, req.body);      entry.markmodified('children');      updated.save(function (err) {       if (err) {            return handleerror(res, err);        }       return res.json(200, entry);     });   }); };
