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。
