Rails 5.0.0.beta1 发布，Action Cable/API 模式

jopen 8年前

Rails 5.0！Rails 团队前几天刚刚庆祝 Rails 1.0发布十周年，现在只是测试版本， 但是 Rails 5.0.0.beta1 已经在生产环境运行 Basecamp 3。

Rails 5.0 Beta1 版本主要改进：全新处理 WebSockets 框架 Action Cable；新 API 模式 --api；Rails 命令都提供在 bin/rails 。

其他值得关注的新特性：

  • New Attributes API by Sean Griffin.

  • The test runner now reports failures inline, so you don't have to complete the suite to see what went wrong.

  • ApplicationRecord has been born as a default parent class of all models created by the generators.

  • ActiveRecord::Relation#in_batches makes it much easier to deal with record work in batches at a time to lessen memory overloads.

  • Post.where('id = 1').or(Post.where('id = 2')) gives you exactly what you'd think!

  • No more accidentally halting Active Record callbacks because the last statement is false. Now you throw(:abort) explicitly!
