Gem 尝试 delayed_job 使用独立数据库之后，script/delayed_job start 无反应，并且报错提示找不到对象
项目需要把 delayed_job 数据库独立出来，创建完新数据库之后，运行RAILS_ENV=production script/delayed_job start无反应，新的 DJ 数据库里能加进去数据，RAILS_ENV=production rake jobs:work能运行，但是会报错说找不到对象，卡了一晚上，谁能帮我看下是哪里写的不对，不胜感激，具体代码如下：
config/initializers/delayed_job_config.rb
Delayed::Job.class_eval do
establish_connection ActiveRecord::Base.configurations["delayed_job"]
end
database.yml
delayed_job:
adapter: mysql2
encoding: utf8
reconnect: false
database: delayed_job
pool: 5
username: root
password: "987654"
host: localhost
my_job.rb
class MyJob < Struct.new(:episode)
def perform
episode.do_something
end
end
DJ 的报错信息提示说找不到 episode，Couldn't find Episode with id=1
