Rails 6 中的自动加载和 Zeitwerk 模式

Autoloading and Zeitwerk Mode in Rails 6

在 Rails 6 的 Zeitwerk 模式中,是否有任何代码贬值?

 class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.2

    # config/application.rb
    config.i18n.load_path += Dir[Rails.root.join("config", "locales", "**", "*.{rb,yml}")]
    config.i18n.fallbacks = true

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration can go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded after loading
    # the framework and any gems in your application.
    config.autoload_paths += ["#{config.root}/app/queries/"]


    # https://gist.github.com/maxim/6503591 (should remove this and fix)
    config.eager_load_paths << Rails.root.join("lib")

我了解到自动加载正在被删除,到目前为止它还没有引起问题,但我想删除不推荐使用的代码。如果折旧了,我该如何加载我的代码?

这里没有任何内容被弃用,但是值得一提的是 documentation:

The array of autoload paths can be extended by mutating config.autoload_paths, in config/application.rb, but nowadays this is discouraged.

Rails 5+ 不鼓励使用手动扩展 config.autoload_paths,因为它可能会在您的生产环境中引起潜在问题。讨论可以追溯到 2013 年,您可以阅读相关内容 here

From Rails 5+ app/ 下的所有目录默认自动加载。如果您想遵循 Rails 建议,则应删除此行

config.autoload_paths += ["#{config.root}/app/queries/"]

并将您的查询目录移动到 "#{Rails.root}/app" 文件夹下。
