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) {
// embedded comment with id `my_id` removed!
});
I'm interested how can I update instead removing this one?
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.

You could do
var comment = post.comments.id(my_id);
comment.author = 'Bruce Wayne';
post.save(function (err) {
// emmbeded comment with author updated
});
Update to latest docs on dealing with sub documents in Mongoose. http://mongoosejs.com/docs/subdocs.html
var Parent = mongoose.model('Parent');
var parent = new Parent;
// create a comment
parent.children.push({ name: 'Liesl' });
var subdoc = parent.children[0];
console.log(subdoc) // { _id: '501d86090d371bab2c0341c5', name: 'Liesl' }
subdoc.isNew; // true
parent.save(function (err) {
if (err) return handleError(err)
console.log('Success!');
});
