Rails 3自定义验证器应该存储在哪里？

我见过文档/网站显示，自定义验证器应该放在项目的 /lib或 /lib/validators目录中。我发现(通过阅读对另一篇文章的回答)它们似乎只在 config/initializers中起作用。是否有人知道，或有一个指针指向官方文件，显示自定义验证器应该居住在哪里？

Here's the official docs about custom validations. AFAIK its a good practice to keep them in the relevant models.

lib/validators seems by far the cleanest. However you may need to load them in before your models, so probably from an initializer.

If you add this to your /config/application.rb file:

config.autoload_paths += %W["#{config.root}/lib/validators/"]

Then Rails will automatically load your validators on start up (just like /config/initializers/), but you keep the clean structure of having your validators in one nice, well named spot.

最佳答案

If you place your custom validators in app/validators they will be automatically loaded without needing to alter your config/application.rb file.
