升级到 Rails 3.2.2:如何解决 Syck::DomainType' 未定义的方法与延迟工作宝石相关的错误? [英] Upgrading to Rails 3.2.2: How to solve the 'undefined method for Syck::DomainType' error related to the Delayed Job gem?

问题描述

我从 3.1.0 开始运行 Ruby on Rails 3.2.2.我有问题

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 ...

使用许多其他人试图解决的 DelayedJob gem:有人成功地解决了这个问题，而其他人则没有.我属于后一类，如果我尝试了我在网上找到的所有解决方案.

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.

此时，在我的 Gemfile 中有:

At this time, in my Gemfile I have:

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

在升级 Rails 之前，在我的 Gemfile 中有:

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'
...

为了发送电子邮件，在我的控制器中，我使用以下代码链接:

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

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

在我的 APPLICATION_ROOT/app/mailers/users/mailer.rb 文件中，我有:

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

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

  def send_register_email(user)
    ...
  end
end

在更新到 Rails 3.2.2 之前，一切正常.现在我在介绍文本中收到了上面提到的错误.如何尝试解决延迟作业问题?

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?

我注意到在与 delayed_job_active_record gem 相关的数据库表中应该有一个名为queue"的列(请参阅 官方文档 了解更多信息).但是，由于我使用的是 gem 'delayed_job' 它存在于该数据库表中.可能是这个问题吗?

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?

我注意到的另一件事如下(但我认为目前这不是问题):

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

$ rake jobs:work

推荐答案

通过确保将 YAML 解析器设置为 Syck 是初始化时绝对要做的第一件事，我们设法解决了应用程序中 Syck/Psych 的怪异问题.您有时会遇到问题的原因是 DelayedJob 的初始化方式因您使用的 YAML 解析器而异，如果解析器在初始化期间发生更改，DelayedJob 可能会出错.

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.

将此添加到 boot.rb 的最顶部，看看是否有帮助:

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

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