Use with Pundit

[davidkrider]

I've "taken the training wheels off" my Pundit setup by adding after_action :verify_authorized to my ApplicationPolicy (which blocks every path not explicitly allowed by policy). I'm using Devise with the two_factor_authentication plugin, and ActiveAdmin. So Devise authentications have now been "absorbed" into the /admin namespace, and the 2-factor controller lives somewhere in the mix. This has been working fine until I forced explicit definitions of policy. Now, when the app tries to serve the page to allow a user to enter the OTP, I get the following error:

I don't know what path/module/namespace/controller/model I'm supposed to be defining to allow this action for all users. How can I cover this path with a Pundit policy? I've tried creating just about every combination of file name, directory path (under /app/policies), and namespace inside the file, but nothing I try even gives me a different error message. Does anyone know the right way to handle this? I can't find a single example on the internet.

Hi, ActiveAdmin has separate authentication namespaces. It doesn't use DeviseController, but rather ActiveAdmin::Devise::SessionsController.

So that's why you can't just easy plug and play two_factor_authentication with AA.

Could you please give me project example? I could check it

The application is proprietary, and already in production, so I can't share it, and it would be hard to remove enough to make it sharable. It just seems like there should be a place in the Pundit gem where I can "see" what the policy name is that the library is trying to find, so that I can write it and place it in the code tree correctly. My best guess so far has been:

/app/policies/active_admin/two_factor_authentication_policy.rb

module ActiveAdmin
	
	class Devise::TwoFactorAuthenticationPolicy

		def show
			true
		end

	end
end

No, I mean you could make separate empty application just with active admin and pundit. And share that new app.
