我正在使用Ruby 2.1.1和Rails 4.1.0.rc1.当执行时rails c,它被锁定.

使用Ctrl-C停止,我得到了错误日志:

~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.2/lib/spring/client/run.rb:47:in `gets': Interrupt
    from ~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.2/lib/spring/client/run.rb:47:in `verify_server_version'

    from bin/rails:3:in `load'
    from bin/rails:3:in `<main>'

弹簧拆除后,rails c恢复.

例如,编辑config/locales/en.yml

en:
  activerecord:
    models:
      user: User
    attributes:
      user:
        name: Name

你可以得到

User.model_name.human # => User

User.human_attribute_name('name') # => Name

但是如何编写Rails 4.1 枚举 I18n值？

错误信息是

xxx.swift:171:45: Cannot convert the expression's type 'NSMutableDictionary!' to type 'StringLiteralConvertible'

代码是

GAI.sharedInstance().defaultTracker.send(GAIDictionaryBuilder.createEventWithCategory("Category", action: "action", label: nil, value: nil).build())

谷歌分析 SDK 版本是

pod 'GoogleAnalytics-iOS-SDK', '3.0.9'

• Xcode 5.1(5B130a)

• iOS 7.1

• 使用CocoaPods

  pod 'Google-AdMob-Ads-SDK'
  

  Run Code Online (Sandbox Code Playgroud)

使用日志编译失败:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_SKStoreProductViewController", referenced from:
      objc-class-ref in libGoogleAdMobAds.a(GADOpener.o)
  "_SKStoreProductParameterITunesItemIdentifier", referenced from:
      -[GADOpener openInAppStore:fallbackURLString:] in libGoogleAdMobAds.a(GADOpener.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

例如,Rails将:'zh-CN'视为:zh

在config/application.rb中

config.i18n.fallbacks = [:'zh-CN'] # or ['zh-CN'.to_sym]

ActionView :: Helpers :: FormBuilder#label将引发

:zh is not a valid locale

我正在使用Rails 4.1.0.rc1,Ruby 2.1.1并保持最新的宝石.
