Delete a key from a MongoDB document using Mongoose

Question

I\'m using the Mongoose Library for accessing MongoDB with node.js

Is there a way to remove a key from a document? i.e. not just set the value to n

Answer 1

if you want to remove a key from collection try this method. this worked for me

 db.getCollection('myDatabaseTestCollectionName').update({"FieldToDelete": {$exists: true}}, {$unset:{"FieldToDelete":1}}, false, true);
