DataMapper ORM v1.8.2

I'm not sure that will work for my situation. I have to be able to be able to separate the relationship between user_types and groups and then for each combination of user_type and group, I add as many resources as needed. So I tried making a model for groups_user_types_resources, with a resource_id and a groups_user_type_id, but I don't know how to use DM to access the join table.

If I do it with a join table with all three, won't that prevent me from separating the assigned user_types for each group from the assigned resources for that groups_user_types combination? Or are you suggesting that I use the table to either have a user_type_id and group_id (to represent the first combination), or all three (to represent a particular permission for a resource for that combination of user_type and group?
