Errata: 2.3.2 app_component/engine.rb Formatting Fix Suggestions

[aaronkelton]

At the end of section 2.3.2 in the eBook, the code is correct, but the formatting was perplexing me for some time. The end for the initializer do..end looks like it closes the class definition. And the 2-space tabbing goes to 3 in the generators block.

I've updated mine to look as follows:

module AppComponent
  class Engine < ::Rails::Engine
    isolate_namespace AppComponent

    initializer :append_migrations do |app|
      unless app.root.to_s.match(root.to_s+File::SEPARATOR)
        app.config.paths["db/migrate"].concat(
            config.paths["db/migrate"].expanded)
      end
    end

    config.generators do |g|
      g.orm             :active_record
      g.template_engine :slim
      g.test_framework  :rspec
    end
  end
end

In the printed version of the book the end in line 10 isn't properly indented. Otherwise, it looks exactly like @chemturion's version.

Thanks!
