how do .group()?

[AbS_]

Hi,
How i can do something like this:
db.posts.group({key: {region:true}, $reduce: function(){}, initial:
{}})

on Mongoose?

I have the same question.  This possible, digging into the docs and code base couldn't find anything.  My gut is just do separate queries for each 'group'.  Can anyone shine some light on this?

[Jeroen Bourgois]

Yes, I would need it to. Any updates on how to achieve this? Makes a
big difference if you have to get +5000 documents from the db, filter
them in your app and do the grouping yourself. Really slow :(

Got it!

Model.find({}, [fields], {'group': 'FIELD'}, function(err, logs) {
...
});

Is this still working with 1.3.7?

I have list of People and I want them to be grouped by lastname, so i
did:

People.find({},[],{'group': 'lastname'},function(err,people){
...
});

But it returns the same like:

People.find({},function(err,people){
...
});

and there is no error.

Bump... Has anyone achive that in version 2.5.x?

you can use this:

Model.collection.group(keys, condition, initial, reduce, finalize,
command, callback);
