Hi Pankaj, I don't know how to do this with named_scope, but maybe you'll like this:
class User
has_many :pending_friends, :through => :friendship, :source => :friend,
:conditions => {'friendships.is_accepted' => 'true'}
end
However, you can't do sth. like
@user.pending_friends << @friend
anymore in this way. See:
