== What?
class User < ActiveRecord::Base
scoped_proxy :role do |role|
{
:find => { :conditions => ['role = ?', role] }
}
end
scoped_proxy :deleted, :find => {
:conditions => 'deleted_at is not null'
}
end
admins = User.role('admin')
admins.count # => 12
admins.find(:all) # => [ ... ]
User.deleted.count # => a number

Swiss.rb is a small project for a small country. Here we'll release all sorts of small projects that we would not release otherwise - partly issued by the local ruby user group, partly things we develop for applications.
ScopedProxy is a small plugin for ActiveRecord that allows you to name a set of sql conditions (like role('admin')) and then access it through that name. Really the logical consequence of with_scope!
This latest version has default proxies that take effect when no other proxy is in effect. This is quite useful for always restricting search, not just when using a named proxy.
