Composed natural keys

[sfeu]

Hi,

there is still a problem with natural keys. If there is more than one key
defined, the common query does not work anymore.

    it "should find elements with two natural keys" do
      class Foo
        include DataMapper::Resource
        property :key1,   String, :key => true
        property :key2, String, :key => true
      end
      DataMapper.finalize

      Foo.create(:key1 => "value1", :key2 => 'value2')
      Foo.first(:key1 => "value1").key2.should == 'value2'
    end

+1332267068.573186 (db 15) "select" "15"
+1332267068.573313 (db 15) "incr" "foos:key1:key2:serial"
+1332267068.573524 (db 15) "sadd" "foos:key1:key2:all" "value1value2"
+1332267068.573687 (db 15) "hmset" "foos:value1value2" "key1" "value1" "key2" "value2"
+1332267068.574434 (db 15) "sismember" "foos:key1:key2:all" "value1"
+1332267068.575936 (db 15) "select" "15"
+1332267068.576032 (db 15) "flushdb"

composite key look-up fails as well

Foo.get("value1","value2").key2.should == 'value2'
