model populate and lean

[Edu]

Hi

Is it possible to use model populate and lean()?

I've read on the documentation that

Model.findOne().lean().populate(whatever).exec(...) 

the result will be a plain javascript object, right?

but, how can I use the lean option on model populate? for instance:

User.populate(user,{path:'messages'},function(err,user){...}); // I want user to be lean

help please!

A few ways:

1: 

inside your callback, do:

user = user.toObject();

user is now a plain javascript object.

2: on your schema, do:

schema.set('toObject', { getters: true });

and ALL objects returned from the schema will be plain objects.

Hi Nik,

I need lean() option in order to avoid casting to MongooseDocuments and increase performance.

I'm afraid that with your solution what the code would do is cast to MongooseDocument and then cast to javascript Object. Am I right?

Is there any way to telling mongoose to do a lean populate?

thanks!

User.populate(user, { path: '..', options: { lean: true}},

cb)

Need to update the docs.
