Has_many :through ... am I missing something here?

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

You need to make sure that Admin and Stuff each has_many :permisisons.
Otherwise there’s nothing for them to have_many of each other
:through.

Then call:

admin.stuff

Thanks a lot. That helped get me out of a rut.

Whoops, I meant admin.stuffs. I was thinking it but I guess my
fingers just refused to type it :slight_smile:
