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

Try:

User.findOne({}, function(err, user){
  // user.key_to_delete = null; X
  `user.key_to_delete = undefined;`

  delete user.key_to_delete;

  user.save();
});
