Question

我有一个这样的课程

class RecurringJob
  include ScheduledJob

  run_every 1.hours

  def perform
    puts "perform job"
  end
end

我收到错误说：

预期D：/ASM/source/app/lib/jobs/scheduled_job.rb来定义ScheduledJob

文件定义是这样的：

module Delayed
 module ScheduledJob

def self.included(base)
  base.extend(ClassMethods)
  base.class_eval do
    @@logger = Delayed::Worker.logger
    cattr_reader :logger
  end
end
    ....

 end
end

错误是什么意思？这不是定义吗？

修改

我必须知道，这个类是在rake任务中定义的（除了类之外它是空的，我不知道是否允许）。

更详细的错误：

Rails遵循非常严格的命名约定，包括lib文件。

如果要在Delayed模块中定义ScheduledJob模块，则必须将文件命名为/lib/delayed/scheduled_job.rb

这将使Rails的期望与你的命名相匹配。

为什么我会预期......定义ScheduledJob？
