Remove sub-document from Mongo with mongoose

Question

I am trying to remove an item from a collection that is stored in a mongoose document. My document looks like this:

{
  \"__v\": 3,
  \"_id\": \"5221040475f         


        

Answer 1

Subdocuments now have a remove function. Use as follows from the spec:

var doc = parent.children.id(id).remove();
parent.save(function (err) {
  if (err) return handleError(err);
  console.log('the sub-doc was removed')
});
