ruby-on-rails - Rails 开发环境 Resque.enqueue 不创建作业

Question

我遇到了同样的问题 Rails custom environment Resque.enqueue does not create jobs ，但那里的解决方案对我不起作用。

我正在为几个异步作业使用 Resque。它在 staging 环境中工作得很好，但由于某种原因它在 development 环境中停止工作。

例如，如果我运行以下命令:

$ rails c development

> Resque.enqueue(MyLovelyJob, 1)

没有排队。我使用 resque-web

检查 Resque

如果我在暂存阶段运行它 - 它工作得很好。

$ rails c staging

> Resque.enqueue(MyLovelyJob, 1)

我已经尝试复制 2 环境，它们似乎使用完全相同的配置(database.yml、config/environment 等)，但 development 仍然无法正常工作。

如果我这样做

 > Resque.enqueue(UpdateInstancesData, 2)
 > => true
 
 > Resque.info
 > => {
 >       :pending => 0,
 >     :processed => 0,
 >        :queues => 0,
 >       :workers => 1,
 >       :working => 0,
 >        :failed => 0,
 >       :servers => [
 >       [0] "redis://127.0.0.1:6379/0"
 >   ],
 >   :environment => "development"
 > }

有什么建议可以去哪里调试吗？

我正在通过工头运行应用程序。我的 Procfile 看起来像:

faye: rackup faye.ru -s thin -E production

worker1: bundle exec rake resque:work QUEUE=* VERBOSE=1

worker2: bundle exec rake resque:work QUEUE=* VERBOSE=1

clock: bundle exec rake resque:scheduler VERBOSE=1

web: bundle exec rails s

如前所述，对于 staging，一切正常，工头的日志是:

而对于 development 它似乎并没有排队然后找到工作。如果队列中已有作业(暂存环境中遗留的待处理作业)，则开发工作人员不会处理它。

Answer 1

问题原来是我的 Gemfile 中的 :development 组也有 gem 'resque_spec'。显然这是一件非常错误的事情......
