mongoose. updating embedded document in array

Question

In the a official mongoose site I\'ve found how can I remove embedded document by _id in array:

post.comments.id(my_id).remove();
post.save(function (err) {
         


        

Answer 1

It shoud look something like this:

    YOURSCHEMA.update(
        { _id: "DocumentObjectid" , "ArrayName.id":"ArrayElementId" },
        { $set:{ "ArrayName.$.TheParameter":"newValue" } },
        { upsert: true }, 
        function(err){

        }
    );

In this exemple I'm searching an element with an id parameter, but it could be the actual _id parameter of type objectId.
