//this method for add data to subdocument BlogPost.findById(req.params.postId, function (err, post) { var subDoc = post.comments.id(req.params.commentId); subDoc = req.body; post.save(function (err) { if (err) return res.status(500).send(err); res.send(post); }); }); // alternative second method you can use this BlogPost.findOneAndUpdate({_id: req.params.postId}, {$push:{ subDoc: req.body }}, (err, doc) => { // do something here });
