本文介绍了升级到Rails 3.2.2：如何解决错误“的SYCK :: DomainType未定义的方法'关于延迟作业宝石？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我从3.1.0 on Rails的3.2.2运行红宝石。我有这个问题

 未定义的方法send_register_email \'的#<Syck::DomainType:0x0000012d2346b8>\n/<ABSOLUTE_PATH>/.rvm/gems/ruby-1.9.2-p290/gems/delayed_job-3.0.1/lib/delayed/performable_mailer.rb:6:in执行...

与其他许多人都试图解决DelayedJob宝石：成功的人所做的，别人没有。我属于后一类，另外，如果我想，我在网上找到所有的解决方案。

在这个时候，在我的Gemfile我有：

 宝石轨道，3.2.2
宝石耙
...
创业板delayed_job_active_record
...

在升级Rails的，在我的Gemfile我有：

 宝石轨道，GT〜＆; 3.1.0
宝石耙
...
＃我也用下面的语句运行的Rails 3.2.2，但没有奏效。
创业板的delayed_job
...

为了发送电子邮件，在我的控制器我用code链接如下：

  ::用户:: Mailer.delay.send_register_email（@user）

在我的 APPLICATION_ROOT / APP /邮寄/用户/ mailer.rb 文件我有：

 类用户::梅勒＆LT;的ActionMailer :: Base的
  ...

  高清send_register_email（用户）
    ...
  结束
结束

更新到Rails 3.2.2之前所有的工作作为良好。现在，我得到上面提到的错误，在介绍文字。 我如何可以尝试解决延迟工作的问题？

我注意到，在数据库表相关的 delayed_job_active_record 创业板应该列名为队列（请参阅了解更多信息的官方文档）。然而，因为我是用创业板的delayed_job这是present在该数据库中的表。 可以是什么问题？的

另一件事我注意到的是下面的（但我认为这是没有问题的，现在）：

解决方案

我们设法解决SYCK /精极度紧张的怪事在我们的应用程序，确保设置YAML解析器SYCK是初始化时做了绝对的第一件事。有时你可以遇到问题的原因是，DelayedJob将初始化不同，这取决于YAML解析器你使用，如果在初始化过程中分析器的变化，DelayedJob可能搞错了。

这加入的boot.rb 的最顶端，并看看是否有帮助：

I am running Ruby on Rails 3.2.2 from 3.1.0. I have the issue

undefined method send_register_email\' for #<Syck::DomainType:0x0000012d2346b8>\n/<ABSOLUTE_PATH>/.rvm/gems/ruby-1.9.2-p290/gems/delayed_job-3.0.1/lib/delayed/performable_mailer.rb:6:in perform ...

with the DelayedJob gem that many other people have tried to solve: someone made successfully that, others no. I am in the latter category, also if I tried all solutions I've found on the Web.

At this time, in my Gemfile I have:

gem 'rails', '3.2.2'
gem "rake"
...
gem 'delayed_job_active_record'
...

Before upgrading Rails, in my Gemfile I had:

gem 'rails', '~> 3.1.0'
gem "rake"
...
# I also used the following statement by running Rails 3.2.2 but it didn't work.
gem 'delayed_job'
...

In order to send e-mail messages, in my controllers I use code link the following:

::Users::Mailer.delay.send_register_email(@user)

In my APPLICATION_ROOT/app/mailers/users/mailer.rb file I have:

class Users::Mailer < ActionMailer::Base
  ...

  def send_register_email(user)
    ...
  end
end

Before updating to Rails 3.2.2 all was working as well. Now I get the error mentioned above, in the introduction text. How can I try to solve the Delayed Job issue?

I noted that in the database table related to the delayed_job_active_record gem should be a column named 'queue' (see the "Gory Details" section in the official documentation for more information). However, since I was using gem 'delayed_job' it was present in that database table. Can be that the problem?

Another thing I noted is the following (but I think that isn't the problem, for now):

$ rake jobs:work

解决方案

We managed to solve Syck / Psych weirdness in our app by ensuring that setting the YAML parser to Syck was the absolute first thing done when initializing. The reason you can sometimes run into issues is that DelayedJob initializes differently depending on which YAML parser you're using, and if the parser changes during initialization, DelayedJob will probably get it wrong.

Add this to the very top of boot.rb, and see if it helps:

require 'yaml'
YAML::ENGINE.yamler = 'syck'
