[Solidus 3.2.2] Hello Everyone, I'm doing a fork of the

Spree::Admin::ImagesController

but I get the error

AbstractController::ActionNotFound (The action 'index' could not be found

Indeed by looking in Spree:Admin:ImagesController and Spree:Admin:ResourceController I don't find a index function, I wonder where and how the index action is defined ?

Hi Sabo 👋 I agree that the index action hasn’t been defined in both the controllers, but I think the

images#index

route is available due to the current route definition here: https://github.com/solidusio/solidus/blob/v3.2.2/backend/config/routes.rb#L42-L46 (here is an example of all the routes created through a

resources

definition) Is it possible that you are unintentionally trying to perform the index action in your fork?

Hello @rainer thank you for the response I had intentionnally trying to perform the index action, the goal is for the fork to reproduce the same behavior than

images#index

I (think) understand how the roads are made, but I don't understand how the index action of

Spree::Admin::ImagesController

work because it's not defined neither in ImagesController nor in ResourceController For the "fork" in my route.rb I have:

namespace :admin do
    resources :kits do
      resources :images, controller: 'images_kit' do
        post :update_positions, on: :collection 
      end
    end 
  end

and

admin_kit_images   GET   /admin/kits/:kit_id/images(.:format)   spree/admin/images_kit#index

Perhaps because I changed the controller name to '_images_kit'_ (the fork) the view in admin/images/index is not found ?

Perhaps because I changed the controller name to ‘_images_kit’_ (the fork) the view in admin/images/index is not found ?

Yes I think you are right 👍 I quickly tried to remove the admin/images/index.html.erb and I got the same exception, you may need to try adding a dedicated admin/images_kit/index.html.erb view in your scenario

Yes, it's "working" now I have the error:

NameError in Spree::Admin::ImagesKitController#index
uninitialized constant Spree::ImagesKit

Extracted source (around line #280)
    # unknown.
    def constantize(camel_cased_word)
      Object.const_get(camel_cased_word)
    end

activesupport (7.0.4) lib/active_support/inflector/methods.rb:280:in `const_get'

There is a

model_class

method in `Spree:Admin:ResourceController`: https://github.com/solidusio/solidus/blob/v3.2.2/backend/app/controllers/spree/admin/resource_controller.rb#L144-L146 In your case, starting from the controller name,

model_class

is probably trying to constantize

"Spree::ImagesKit"

. If you want to continue using the

Spree::Image

model, in your

Spree::Admin::ImagesKitController

you can override the

model_class

method with something like this:

private

def model_class
  Spree::Image
end

Thank you @rainer it's working like a charm ;)
