Get values of object using lodash

Question

I've to use lodash for get the values of this object: http://pastebin.com/raw.php?i=U1Z8tzY0

As you can see, I have one big object. I need to get all the autonomias names with the activo property set to true".

I've tried to use a lot of functions without result. I'm stuck.

And I can't find the way to do it properly after few days.

I expect all the autonomias with the activo: true: { "andalucia", "aragon", "asturias", "canarias", etc }. In this file all is set to true, but in a near real example some "autonomias" are going to set to false. — Baumannzone

The following snippet should do the trick:

var res =  _(data)
             .chain()
                .result('autonomias')
                .filter({ activo: true }) 
                .pluck('name')
             .value();

Here is a demo.

You could also use native Array methods:

var res = data.autonomias.filter(function (el) {
    return el.activo === true;
}).map(function (el) {
    return el.name;
});

I know, but needed to use lodash. Thanks you.
