Datamapper DataMapper → 0.10.2

class NoId
  include DataMapper::Resource
  
  property :not_id, Integer, :key => true
  property :other_key, Integer, :key => true
end

irb(main):002:0> NoId.all :order => [:other_key]
 ~ (0.000036) SELECT "not_id", "other_key" FROM "no_ids" ORDER BY "other_key"

Seems ok...

irb(main):003:0> NoId.all :not_id => 1, :order => [:other_key]
 ~ (0.000554) SELECT "not_id", "other_key" FROM "no_ids" WHERE "not_id" = 1

The order by clause is ignored when any of the properties of the composite key are used in the conditions.
