Alias name for nested resources rails routes

Question

I have batch_class model, and under that articles, assignments resources are there. The routes.rb look like this.

resources :batch_classes do
  member do 
    resources :articles, except: [:index] 
    resources :assignments
 end

end

The problem is I am not getting desired URL route. My rake routes for edit assignments shows this.

/batch_classes/:id/assignments/:id/edit(.:format)

with alias name of edit_assignment_path. However, my expected route is

/batch_classes/:batch_class_id/assignments/:id/edit(.:format).

Please help.

Take `resources :assignments` out of member block and do check again — Imran Ahmad, Jun 03 '19 at 04:13

You can have nested routes by just putting nested resource inside parent resources.

resources :batch_classes do
  resources :assignments
end

Then, you surely will have a route called edit_batch_class_assignment_path and you can pass in instances as edit_batch_class_assignment_path(@batch_class, @assignment)

The desired path route can be achieved by taking resources :assignments out of the member block.

resources :batch_classes do
  resources :assignments
  member do 
    #...
  end
end

Going through this document is highly recommended for correct implementation.

I was following this documentation, i am afraid they have put wrong info here. https://guides.rubyonrails.org/v3.2.2/routing.html#nested-resources check the tables under nested-resources section. they have used same `:id` twice in edit route. – Rajan Verma - Aarvy Jun 03 '19 at 09:38
It has been fixed now. – Imran Ahmad Jun 04 '19 at 04:40
The issue is not there in the current version of doc but 3.2.2. – Imran Ahmad Jun 04 '19 at 04:43
