Tried modularising an old rails app. Decided to put some parts in packages while the other parts are in the conventional rails format. After, i run packwerk check but started in run into the issues have detailed below.

Folder structure

  • app
    • controllers
    • models
    • mailers
    • packages
      • package_name
        • app
          - models
          - controllers
        • spec

added to config/application.rb

    config.autoload_paths += Dir[Rails.root / "app/packages/*/app/*"]
    config.autoload_paths += Dir[Rails.root / "app/packages/*/spec/*"]
    config.autoload_paths += Dir[Rails.root / "lib"]

On running packwerk check you get this error We could not extract autoload paths from your Rails app. This is likely a configuration error. (RuntimeError)

When i run bin/rails zeitwerk:check , it indicates that the files in the packages needs to be eagerly loaded. When i do that, i get NameError: uninitialized constant for some files.
