我正在使用延迟的工作，我认为我的序列化问题。我们使用的是ruby 2.2.2。
在我的模型中，我有一个在保存时触发的回调，并为我的模型创建延迟的作业。像这样：
after_create :update_queue
def update_queue
self.class.delay(run_at: 1.minutes.from_now, delayed_reference_id: self.id, delayed_reference_type: "Payment", queue: "qbo_payments").delayed_task(self.id)
end
def self.delayed_task
# Do some stuff
end
但是我收到了错误：
undefined method `delayed_task' for #<Class:0x0000000f93f9b8>

我尝试了什么
经过一些谷歌研究后，我找到了2个修复程序。第一个也是更广泛接受的修复是添加：
require 'yaml'
YAML::ENGINE.yamler = 'syck'
#https://github.com/collectiveidea/delayed_job/issues/199
但是，ruby 2.2.2
不再支持syck第二个解决方案似乎只是加剧了问题，就是在我的delayed_job启动脚本中添加“bundle exec”，如下所示：
run "cd #{current_path}; bundle exec script/delayed_job start #{rails_env}"
答案 0 :(得分：0)
这会有效！
after_create :update_queue
def update_queue
self.delay(run_at: 1.minutes.from_now, delayed_reference_id: self.id, delayed_reference_type: "Payment", queue: "qbo_payments").delayed_task()
end
def delayed_task
self.class.delayed_task(self.id)
end
def self.delayed_task
# Do some stuff
end
