In Rails when a resource create action fails and calls render :new, why must the URL change to the resource's index url?

Question

I have a resource called Books. It\'s listed as a resource properly in my routes file.

I have a new action, which gives the new view the standard:

@         


        

Answer 1

It can be fixed by using same url but different methods for new and create action.

In the routes file following code can be used.

resources :books do
  get :common_path_string, on: :collection, action: :new
  post :common_path_string, on: :collection, action: :create
end

Now you new page will render at url

books/common_path_string

In case any errors comes after validation, still the url will be same.

Also in the form instead using

books_path

use

url: common_path_string_books_path, method: :post

Choose common_path_string of your liking.
