Currently, I have 3 models User Group Permission Users and Groups have a HABTM relationship and Groups and Permissions have a HABTM relationship. For purposes of authorization, I need to know if a user belongs to a particular group that has a particlar permission to determine if they can perform an operation. What's the best way to go about this?

Have the user ask its groups if any of them have the permission in question: target_permission = Permission.find(...) user.groups.any? do |group| group.permissions.include?(target_permission)} end
