Order being ignored by Rails with comma gem

Question

I have the following call using comma gem:

def by_location_csv
  @inventory_items=InventoryItem.where('location_id=? and is_deleted=false',params[:location_id]).order(:bin_number)
  render :csv => @inventory_items
end

but the order is ignored with this in the log:

Scoped order and limit are ignored, it's forced to be batch order and batch size

Is there any workaroud to this? can I pass in an option to up the batch size or just turn it off?

Answer 1

in your example, comma is being used during the rendering, not the ordering.

examine the sql generated by each of your chained scope methods to resolve the ordering.

Answer 2

A bit late, but for anyone else with the same issue then I've found all you need to do is append '.all' to the variable/query, e.g.

render :csv => @inventory_items.all
