ruby - `threadsafe!` rails 中缺少方法

转载作者：数据小太阳更新时间：2023-10-29 07:44:02

为了在 Rails 中启用多线程，我在 development.rb 中设置了 config.threadsafe!。

我收到一条错误消息:

'method_missing': undefined method `threadsafe!' (NoMethodError)

我使用的是 rails 4.1.1 和 ruby 2.0.0。请任何人帮助我解决这个问题的理由和方法。

development.rb:

Rails.application.configure do
  config.cache_classes = false
  config.threadsafe! 
  config.eager_load = false
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.active_record.migration_error = :page_load
  config.assets.debug = true
  config.assets.raise_runtime_errors = true
end

错误:

最佳答案

config.threadsafe! 不再需要，已被删除。 Rails 默认是线程安全的。它在这个配置选项上所做的一切被证明对多进程单线程部署也有效，所以现在它只做这个操作。
