redirect_to object in admin namespace

Question

In Rails you can pass an object to redirect_to if you've declared it as a resource in your routes:

redirect_to @post

I have a polymorphic object Attachment that belongs to an owner. @attachment.owner could be any object. I need to redirect to the attachment's owner, but both attachment and its owner are resources within an admin namespace:

namespace :admin do
  resources :attachments, :posts, :comments #etc
end

If I knew the @attachment.owner was a post, I could redirect_to admin_post_path(@attachment.owner), but since it could be any object, how to I do the redirect?

Answer 1

You can use polymorphic_path

polymorphic_path([:admin, @attachment.owner])
