node.js - mongoose stringify removes empty elements -

i retreiving mongoose object empty values mongo db :

{ _id: 53049728456d4416243bf65f,   usercreated: {},   status: { usercreated: {} },   user: 'patrice', } 

which fine because there no data.

but when stringify json.stringify(obj) :

{ _id: 53049728456d4416243bf65f,   user: 'patrice' } 

the keys usercreated , status haven't been stringified , don't appear in output...

any idea comes , how arrount ?

my model :

new mongoose.schema({   user: type: string, default: '',   status: {     name: { type: string, default: '' },     usercreated: {       time: { type: date, default: date.now }     }   },   usercreated: {     time: { type: date, default: date.now }   } }) 

p.

json.stringify doesn't strip empty objects, mongoose specific.

i'd recommend trying .toobject() or .tojson()

http://mongoosejs.com/docs/api.html#document_document-toobject

this 1 called during .stringify cutting out empty objects. http://mongoosejs.com/docs/api.html#document_document-tojson

so try first:

json.stringify(obj.toobject());
