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 ?
