Question

Suppose I have a document for example: var doc = Model.findOne({name:”name”});

Now if the document gets edited trough another connection the the database, doc doesn’t hold the right information. I do need it, so I have to “refresh” or “redownload” it from the database. Is there any way to do this with only the object “doc”?

Answer 1

Assuming doc contains the document instance to refresh, you can do this to generically refresh it:

doc.model(doc.constructor.modelName).findOne({_id: doc._id},
    function(err, newDoc) {
        if (!err) {
            doc = newDoc;
        }
    }
);

However, it’s better to not persist/cache Mongoose document instances beyond your immediate need for them. Cache the immutable _id of docs you need to quickly access, not the docs themselves.
