Answer 1

You need to create an Object for Company to assign its properties
var news = new Categories();
var company = new Company();
news.company = company;
news.name = 'test category'
company.name = 'test company';
console.log(company);
console log
{ name: 'test category',
company: { _id: 5a61629b74f8df0bd73142ba, images: [] },
_id: 5a61629b74f8df0bd73142b9 }
{ name: 'test company', _id: 5a61629b74f8df0bd73142ba, images: [] }

You can post your data in json format and use bodyParser.json() middleware in your app.js, and your backend code can be this:
router.post('/', function(req, res, next) {
var news = new Categories(req.body); // create record directly with the json data
console.log(req.body.company.name); //just access it directly
news.save(function (err) {
if(err) {
console.error(err);
res.json({result: 0});
return;
}
res.json({result: 1});
});
});
and json format can be this:
{
"company": {
"name": "test company name",
"url": "http://test.com",
"image": []
},
"name": "test name"
}
