node.js - mongoose: Sorting by id -

mongo db reorders documents when ever document updated. dint want happen found using order _id homecoming documents in consistent order. not able sort. below find query finds posts created particular user , trying sort _id. code:

app.get('/posts/:user_id',function(req,res){ posts.find({ 'creator.user_id':req.params.user_id },[],{ sort: { '_id': -1 } },function(err,userpost){ if(err) res.send(err); res.json(userpost); }) });

the sec parameter fields select. need add together options 3rd parameter:

posts.find({'creator.user_id': req.params.user_id}, null, {sort: {'_id': -1}}, function(err,userpost) { if(err) res.send(err); res.json(userpost); });

alternatively can utilize sort() function:

posts.find({'creator.user_id': req.params.user_id}).sort({'_id': -1}).exec(function(err,userpost) { if(err) res.send(err); res.json(userpost); });
