Ruby on Rails

Thanks Colin for your answer

let me draw the big picture :
in my iatme controller ,before the display ( scope and pagination) , I
searched for geolocalized data of item ( with distance from the
search), and I get a sorted array of Item Ids, (already sorted on the
distance : item_ids = [ 5, 2, 1, 10, ...] )


then I display the items using Kaminari pagination ( Kaminary doesn't
paginate an array )

@items = Item.geo_filtered_with(geo_ids).page params[:page]

and my model scope is :

scope :geo_filtered_with, lambda { |item_ids|
where(:id => item_ids)
}

so I wonder if the result of the scope will keep the same order as the
item_ids
which means :
items.id IN [ 5, 2, 1, 10, ...] will always get items records 5, 2,
1, 10 .... in this order

that's why I did not specified a sort order with the scope, is it
clear ?
