RoR API RABL collection to array

RABL Current Code :

object @region
attributes :id, :name, :latitude, :longitude, :region_id
child :sub_regions do
  attributes :name
end

I get the following output :

{
    "id": 1,
    "name": "test",
    "latitude": "30.932351",
    "longitude": "92.83391",
    "region_id": 1,
    "sub_regions": [{
            "name": "1"
        }, {
            "name": "2"
        }, {
            "name": "3"
        }, {
            "name": "4"
        }, {
            "name": "5"
        }, {
            "name": "6"
        }, {
            "name": "7"
        }
    ]
}

I want to remove name attribute and just display the values as an array But what I want is to convert the collection to an array like the output here :

{
    id: 1,
    name: "test",
    latitude: "30.932351",
    longitude: "92.83391",
    region_id: 1,
    sub_regions: [
            "1",
            "2",
            "3",
            "4",
            "5",
            "6",
            "7"
    ]
}

The closest I can get to this is by this RABL code :

code :sub_regions do |s|
  s["name"]
end


{
    {
          id: 1,
          name: "test",
          "latitude": "30.932351",
          "longitude": "92.83391",
          region_id: 1,
          sub_regions: "1"
    }

}

By the above code block in show.json.rabl it displays only the first element, how do i make it an array with all the elements?

joe nayyar had the right idea in his answer, but there's a cleaner way than using object false.

child :sub_regions do
  attributes :name
end

becomes...

node :sub_regions do |region|
  region.sub_regions.collect(&:name)
end

For anyone lazy roaming around for solution like me, as RABL is on top of the ruby code base you can do something like:

object false 
node :region, :object_root => false do 
{:id => @region.id, :name => @region.name, :latitude=> @region.latitude, :region_id =>  @region.region_id, :sub_regions=>@region.sub_regions.collect(&:name)}
end

It is because you used object @region when you should have used collection @region
