I have three models. Admin, Stuff, Permission.
Each admin can do lots of stuff, but only if they have permission. I
have the following relationship set up:
class Admin
has_many :stuffs, :through => :permissions
end
class Stuff
has_many :admins, :through => :permissions
end
class Permission
belongs_to :admin
belongs_to :stuff
end
I want to be able to see the permissions an admin has so I call:
admin.stuff and expect an array of stuff they have permission to. Am
I completely missing the boat here?
Thanks,
Bryce

Then call: admin.stuff David -- Upcoming Rails training by Ruby Power and Light: Four-day Intro to Intermediate May 8-11, 2007 Edison, NJ http://www.rubypal.com/events/05082007 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi --> > Then call: > > > > admin.stuffWhoops, I meant admin.stuffs. I was thinking it but I guess my fingers just refused to type it :-) David -- Upcoming Rails training by Ruby Power and Light: Four-day Intro to Intermediate May 8-11, 2007 Edison, NJ http://www.rubypal.com/events/05082007 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
