How to apply 301 redirect to link that no longer exists because record was deleted

If I delete a product from the database, the link associated with it no longer works and returns a 404 error such as

https://www.luminoto.com/wallpapers/burnt-down-forrest-ca-2006

In rails, how can I make sure that all deleted products get redirected to my homepage saying that product longer exists?

if its just a matter of showing link which actually do not work..you can use link_to_if

Creates a link tag of the given name using a URL created by the set of options if condition is true, otherwise only the name is returned.

<%= link_to_if(@product.present?, "Show More", { controller: "sessions", action: "new" }) %>

You can do something like:

class ProductsController < ActionController::Base
  rescue_from ActiveRecord::RecordNotFound, with: :record_not_found

  private def record_not_found
    redirect_to controller: 'home', action: 'index', alert: 'Product no longer exists'
  end
end

Check http://guides.rubyonrails.org/action_controller_overview.html#rescue-from for more info.
