Question

I am adding an admin namespace with a few controllers, so our stuff can edit contents from the backend.

For example, I have a Book model, and a books_controller allowing guests browse. Now I am adding an admin/books_controller, providing a backend for admins to edit books.

  namespace :admin do
    resources :books, except: :show
  end
  resources: books, only: [:index, :show]

Currently for all the link_to and form_for in the admin_books_controller views, I need to add the namespace :admin like this:

<%= form_for([:admin, @post]) do |f| %>

(in the normal controller it would be form_for(@post))

It gets a bit repetitive, and I am wondering if I can set it somewhere in the admin controller so all the link_to within that controller will route in the admin namespace?

Answer 1

If you scope the model under the namespace, that should automatically be reflected in the form generator.

So something like rails g model admin/book will generate a book model nested under the admin namespace.

If you then build a form atop that object, something like form_for Admin::Book.new this should target any appropriately nested routes, such as:

namespace :admin do
  resources :books
end

I hope this gives some indication of a direction that you can try out.

Best regards.
