This is a followup to Easiest way to copy/clone a mongoose document instance?, which isn't working for me.
The following code throws a "cannot edit Mongo _id" field, rather than wiping the ._id and creating a new document in the collection.
Is there a better way to clone all values of a document into a new document, for further use/testing/etc?
I'm on Mongoose 3.8.12/Express 4.0, and I have also tested this on creating a new ObjectID in the 'undefined' s1._id field below.
router.route('/:sessionId/test/:testId')
.post(function(req,res){
Session.findById(req.params.sessionId).exec(
function(err, session) {
var s1 = new Session();
s1 = session;
s1._id = undefined;
console.log('posting new test', s1._id); // your JSON
s1.save(function(err) {
if (err)
res.send(err);
res.json( 'new session ', req.body );
});
}
);
});
