Question

right now, i do this in command line:

var obj = db.mycollect.find({id="231412"});
obj.abc = 'new value';
obj.save();

3 lines of code..

is there a simpler way to do this?

e.g. db.mycollect.find({id=12345}).save({abc:'new value'});

Answer 1

db.mycollect.update({id=12345}, {"$set": {abc:'new value'}});

This is not only one line but also atomic. With your solution if somebody updates the document after you’ve read it but before storing it that modification will be lost.
