Rails - Nov 2012 - Active record queries, reverse lookup on has_many: :through =>

*User.rb*  
has_many :looking_for_whos, :class_name => "UserLookingForWho"
has_many :asset_looking_for_whos, :through => :looking_for_whos
belongs_to :asset_usertype 

In a controller i can do the following: 

*@users = User.where(asset_usertype_id: [current_user.looking_for_who_ids])*
to get all users who''s *asset_user_type_id* is in
*looking_for_who_ids*,
but the trick i would like to add a reverse lookup as well; to maker sure 
that Users selected *also* is 
looking for the current_user.asset_usertype_id. But i cant get my head 
around what to do, someone 
who could give me some pointers ?
