Polymorphic Rails reference for nested index action

Question

I have been trying to find this link for several hours. I have a polymorphic association in which there are both collections and an assortment.

Collection Model

has_many :designs, :as => :targetable

Assortment Model

has_many :designs, :as => :targetable

Design model

belongs_to :targetable, :polymorphic => true

To associate a show action with a design, the correct polymorphic path is:

link_to polymorphic_path([@targetable, @design])

But I can’t understand how to associate a design page with an index to show all the projects associated with it corresponding to the target.

Does anyone know a suitable link to get there?

Answer 1

Finally, I was able to find the answer.

polymorphic_path([@targetable, Design])

targetable/:targetable_id/designs
