Find, .map and Distinct

@rate_types = PerformerCategoryRate.find( :all,
:conditions => [
“performer_category_id = ?”,
@calc_sheet_performer_line.performer_category.id ],
:select => “DISTINCT
rate_type_id, min(id)”,
:group => “rate_type_id” ).map
{ |pc| [pc.rate_type.name, pc.id ] }

I’m sure it’s something simple, but when I use the above command, and
assign @rate_types to a select group, the value is not set on the items,
however the name is.

Anyone know what I’m doing wrong?
