ruby rake with rails 在生产中缺少常量，但在开发环境中工作

Question

我有一个 rake 任务在开发环境中运行正常，但在生产环境中运行不正常。

task :sample_test_quote => :environment do

  QuoterTester.test

end

QuoterTester 是一个带有类方法测试的模型类。

在 dev 下运行任务正常，如下所示:

rake sample_test_quote

而在产品下，我得到了这个:

$ RAILS_ENV=production rake sample_test_quote --trace
** Invoke sample_test_quote (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sample_test_quote
rake aborted!
uninitialized constant QuoterTester

我正在使用 JRuby 1.6.5 和 mysql - prod 和 dev database.yml 的设置几乎相同。同样使用 Gemfile - 见下文。

从这里question ，我猜这是项目中某个类的问题。

那么，关于如何追踪哪个类(class)有什么技巧吗？

奇怪的是，rails server/console 都在生产环境中工作——我原以为它们也会失败。

TIA，克里斯

如果启用了 config.threadsafe!，当 Rake 任务在生产模式下运行时，这是一个相当常见的问题，这应该适用于 JRuby 应用。

一个可能的解决方法是编辑您的环境，以便仅在您运行 Rake 任务时禁用 config.threadsafe!(您可以为此目的构建您自己的环境变量)。
