uninitialized constant Pundit::Authorization

[albertski]

Below is a simplified version of a concern I use in my Controllers.

module One
  module Two
    module PunditAuthorization
      extend ActiveSupport::Concern
      include Pundit::Authorization
    end
  end
end

When I upgraded to Rails 7, I got the following error:

my-engine/controllers/concerns/one/two/pundit_authorization.rb:6:in `<module:PunditAuthorization>': uninitialized constant One::Two::PunditAuthorization::Pundit (NameError)

      include Pundit::Authorization
              ^^^^^^^^^^^^^^^

The issue disappears if I use include Pundit instead of include Pundit::Authorization. Should we be using include Pundit::Authorization in Rails 7?

No, include Pundit is deprecated and will be removed in a future release.

With the limited information provided my first guess is that you might be using an old version of Pundit?

[albertski]

Thanks. I am using the latest (v2.3.1). The pundit gem is included in one of our engine gems so let me keep digging to see if something isn't set up correctly on our end.

[Burgestrand]

I didn't notice the hint in the error, but there's one:

uninitialized constant One::Two::PunditAuthorization::Pundit

I'm not sure why include Pundit::Authorization would be different from include Pundit in your case; but because of this error message I'm guessing include ::Pundit::Authorization would work here (note the prefix ::).

Sorry for the late response @Burgestrand and thanks for the suggestion.

Turns out I wasn't using the latest version of Pundit. I had multiple gems requiring pundit and one of them was still on an older version. I have it working with include Pundit::Authorization.

Thanks for replying, that's good news!
