access_grant_class is broken.

[Exterm1nate]

Steps to reproduce

# config/initializers/doorkeeper.rb
Doorkeeper.configure do
  access_grant_class "Oauth::AccessGrant"
end

# app/models/oauth/access_grant.rb
require "doorkeeper/orm/active_record/mixins/access_grant"

module Oauth
  class AccessGrant < ActiveRecord::Base
    include ::Doorkeeper::Orm::ActiveRecord::Mixins::AccessGrant

  end
end

When starting application an error occures:

NameError: uninitialized constant Oauth
    Object.const_get(camel_cased_word)

I tried to require model in the initializer and the error changed:

Doorkeeper::MissingConfiguration: Configuration for doorkeeper missing. Do you have doorkeeper initializer?

With other two classes (access_token_class, application_class) application starts correctly.
Seems that lib/doorkeeper/openid_connect/orm/active_record.rb:35 is not working.

System configuration

Rails version: 7.0.3

Ruby version: 3.1.2

Doorkeeper version: 5.5.4

Doorkeeper OpenID version: 1.8.2

Thanks for reporting this!

Could be related to @nov changes here #168, I'll take a look closer a little bit later

I couldn't reproduced the error in this sample app.

Are you missing app/models/oauth.rb which defines Oauth constant?

[Exterm1nate]

I debuged my application and came to the conclusion that the problem is in the Sorcery gem.
Updated your sample app to demonstrate it.

Ah, because you have oauth gem, OAuth is already defined...

[Exterm1nate]

It doesn't matter what class is provided.

The same issue for any other model, without Oauth namespace.

Doorkeeper.configure do
  access_grant_class "ApplicationRecord"
end

It seems because of Sorcery bug, which should be fixed in Sorcery v1.

Does doorkeeper-openid_connect need some changes?

Think we can close this.
