I installed the DataMapper ORM, it works well, but i would like to join two tabes but i don't know how to succeed.

I have one table:
pk: id_category

The second table
pk: id_category
pk: id_shop

I just want to join to produce a sql query like: SELECT * FROM ps_category AS c LEFT JOIN
ps_category_lang AS cl ON c.id_category = cl.id_category ;

I have two model CategoryModel and Category who inherit DataMapper.
Can you please tell me how to do this?
Thank you
