How to render / fetch JSON data

[lpe]

In my Stimulus Controllers I need to fill in a field in a form (create / edit) with informations based on a select. Typically a description based on the product id. This is what I usally do via a change event action :
... .fetch(/products/${id}) .then((response) => response.json()) ...
How can I add json rendering (normally in the controller) on Avo without side effects (as I See' You shouldn't need to modify it in order to use Avo.').
Thx by advance for your help.

You can add actions to a controller. We should remove that message.

Thx. It seems that we ca'nt override the show method with something like :

def show
        respond_to do |format|
            format.html ...
            format.json ...
            end
    end

Right ? So I suppose I need a specific method to be able to fetch a record in json ?
Thx by advance.

Hey @lpe. Apologies for not mentioning it.

Yes. you would need to create a separate route and controller action.

if defined? ::Avo
  Avo::Engine.routes.draw do
    scope :resources do
      get "products/api/index", to: "products#api_index"
    end
  end
end

This is just a sample of the controller method. You can go wild or make your own controller.

For v3.0 we're thinking of improving this.

Thank you!
