Mongoose populate after save

node.js mongodb mongoose populate

You should be able to use the Model's populate function to do this: http://mongoosejs.com/docs/api.html#model_Model.populate In the save handler for book, instead of:

book._creator = user;

you'd do something like:

Book.populate(book, {path:"_creator"}, function(err, book) { ... });

Probably too late an answer to help you, but I was stuck on this recently, and it might be useful for others.

The solution for me was to use execPopulate, like so

const t = new MyModel(value)return t.save().then(t => t.populate('my-path').execPopulate())

In case that anyone is still looking for this.

Mongoose 3.6 has introduced a lot of cool features to populate:

book.populate('_creator', function(err) { console.log(book._creator);});

or:

Book.populate(book, '_creator', function(err) { console.log(book._creator);});

But this way you would still query for the user again.

A little trick to accomplish it without extra queries would be:

book = book.toObject();book._creator = user;
