In my current Rails project, I use the aegis gem for rights management. And I almost got mad, wondering, why it wouldn’t work..\n@(ruby)[permissions.rb]
permission :access_photo do |user_or_group,photo|
allow :user do
user_or_group.allowed_photos.first == photo
end
end@

which was called like this (I know, it’s a little bit unDRY):

user.may_access_photo?(user,photo)

After some nerve-wracking debugging, I realized, that the first block parameter of the permission block is reserved for the “self”-user, on which you ask..
