CType has many Field Field has many Ctype

and of course the tables used are fields, ctypes, and ctypes_fields. Normally, the ctypes_fields table should contain only ids referencing the other two tables. However, i'd like to put there a "options" field that will contain some content for the concrete instance only. I walked through all DataMapper tuts but I could'n find relevant info on how I could extract these specific values (the ones in the relation table)

Ben bu ilişki tablo için ayrı bir model oluşturmak ya da bunu yapmak için akıllı bir yol var mıdır?
