node.js - Mongoose not returning full dataset -

i have model set so:

var post = mongoose.schema({        "_uid": string,       "post_title": string,       "post_content": string,       "post_date": date,       "user": string,       "slug": string,       "attached_media": [[         {           "format": string,           "type": string,           "small": string,           "medium": string,           "large": string         }       ]],       "likes_count": number,       "likes": [         {.... 

the key part of attached_media array, whenever use .find({}) command mongoose none of array elements return data inside them. data inside them when use mongo command shell see arrays populated.

my find method:

post.statics.getall = function getall(next){   this.find({})   .sort({'post_date':'desc'})   .exec(function(err, doc){     if(err) console.log(err)     next(null, doc)   }) } 

mongoose returns:

[ { attached_media: [],     likes: [],     comments: [],     __v: 0,     _uid: '577e67d2a4387d0b1b480e2c',     user: 'aaron griffin',     post_title: 'this should couple of images',     post_date: tue jul 12 2016 13:40:06 gmt+0000 (utc),     post_content: '',     _id: 5784f33681adc21c121a94d1 },   { attached_media: [],     likes: [],     comments: [],     __v: 0,     _uid: '577e67d2a4387d0b1b480e2c',     user: 'aaron griffin',     post_title: 'hello',     post_date: tue jul 12 2016 13:34:03 gmt+0000 (utc),     post_content: '',     _id: 5784f1cb81adc21c121a94d0 } ] 

but should return (what mongo shell returns):

{ "_id" : objectid("5784f33681adc21c121a94d1"), "post_content" : "", "post_date" : isodate("2016-07-12t13:40:06.486z"), "post_title" : "this should couple of images", "user" : "aaron griffin", "_uid" : "577e67d2a4387d0b1b480e2c", "comments" : [ ], "likes" : [ ], "attached_media" : [ { "large" : "large_f087dd83f697e3742d249e45d47f102b.jpg", "medium" : "medium_f087dd83f697e3742d249e45d47f102b.jpg", "small" : "small_f087dd83f697e3742d249e45d47f102b.jpg", "type" : ".jpg", "format" : "image/jpeg" }, { "large" : "large_fe6dfb7bfcff38883badb800d049dc19.jpg", "medium" : "medium_fe6dfb7bfcff38883badb800d049dc19.jpg", "small" : "small_fe6dfb7bfcff38883badb800d049dc19.jpg", "type" : ".jpg", "format" : "image/jpeg" }, { "large" : "large_527b0b9eb14f4310e535eae2c6e48f4a.jpg", "medium" : "medium_527b0b9eb14f4310e535eae2c6e48f4a.jpg", "small" : "small_527b0b9eb14f4310e535eae2c6e48f4a.jpg", "type" : ".jpg", "format" : "image/jpeg" } ], "__v" : 0 } { "_id" : objectid("5784f1cb81adc21c121a94d0"), "post_content" : "", "post_date" : isodate("2016-07-12t13:34:03.848z"), "post_title" : "hello", "user" : "aaron griffin", "_uid" : "577e67d2a4387d0b1b480e2c", "comments" : [ ], "likes" : [ ], "attached_media" : [ { "large" : "large_c869348bfc5f12f4099a0f6e2d8941ae.jpg", "medium" : "medium_c869348bfc5f12f4099a0f6e2d8941ae.jpg", "small" : "small_c869348bfc5f12f4099a0f6e2d8941ae.jpg", "type" : ".jpg", "format" : "image/jpeg" } ], "__v" : 0 } 

the code runs , logs query:

router.get('/', function(req, res, next) {   if (req.user) {     if(req.user.registration_level == 1){       res.redirect('/signup/complete')     }     post.getall(function(err, posts){       // console.log(req.user)       console.log(posts)       res.render('dashboard', { title: 'member feed' , posts: posts, user: req.user });     })   } else {       res.render('index.ejs', { title: 'express' });   } }); 

if knows maybe why isn't working i'll appreciate :)

i not sure have used array of array there... can replace array of 1 level this.

var post = mongoose.schema({    "_uid": string,   "post_title": string,   "post_content": string,   "post_date": date,   "user": string,   "slug": string,   "attached_media": [     {       "format": string,       "type": string,       "small": string,       "medium": string,       "large": string     }   ],   "likes_count": number,   "likes": [     {....
