带有rails的ruby rake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 dev env 中运行正常，但在 prod 中却不行。

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 下运行任务可以正常工作，如下所示：

rake sample_test_quote

而在 prod 下，我明白了：

$ 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

我使用 JRuby 1.6.5 和 mysql - prod 和 dev database.yml 的设置几乎相同。也使用 Gemfile - 见下文。

从这个question，我猜它是项目中的一个类的问题。

那么，关于如何追踪哪个班级的任何提示？

奇怪的是，rails 服务器/控制台都在 prod 环境中工作 - 我原以为它们也会失败。

Answer 1

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，它应该适用于 JRuby 应用程序。

一种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!（您可以为此目的创建自己的环境变量）。
