Deep has_many through

Hey everyone,

I tried searching for this and asking in #rubyonrails but got no answer.

Given: class Aye; has_many :bee; end class Bee; has_many :cees; end class Cee; has_many :dees end

Is this possible?: aye.dees

I know how that with has_many through you can get aye.cees but can it go further than that?

While searching I came accross http://wiki.rubyonrails.org/rails/pages/ThroughAssociations that talked about it (but this was a wish): class Manufacturer   # using an array specifies the order in which the relationships occur.   has_many :review_comments, :through => [:products, :reviews]   # For that matter, we should be able to string together as many relationships as we like.   # For example, for intergalactic commerce, we might want to find out which moons are associated with a given manufacturer.   has_many :moons, :through => [:distributors, :space_stations, :planets, :moons] end

Thanks, Ramon Tayag

Hi,

you provide your own answer :slight_smile:

class Aye   has_many :bees # plural !   has_many :cees, :through => :bees # this specifies which class is intermediary end class Bee   has_many :cees end class Cee   has_many :dees end

And then you can use Aye.dees.
