延迟作业(2.1.4) + Rails(3.0.10) 未定义方法“延迟”
我将rails应用程序升级到rails（3.0.10）并更新gemelasted_job。我更新了表elaided_job的迁移，但不幸的是方法“.delay”不起作用。
NoMethodError: undefined method `delay' for #<User:0x10394d140>
我没有找到解决方案。我做了：“捆绑安装”，我重新启动了服务器，尝试安装为插件......
你有什么想法吗？
谢谢。
更新：
我解决了问题，但创建了一个文件 config/initializer/delayed_job.rb
require 'delayed_job'
Delayed::Worker.backend = :active_record
I upgrading a rails application to rails(3.0.10) and update the gem delayed_job. I updated my migration for the table delayed_job but unfortunatly the method ".delay" doesn't work.
NoMethodError: undefined method `delay' for #<User:0x10394d140>
I didn't find a solution for that. I did : "bundle install", I restarted the server, tried to instal as plugin...
Do you have any ideas?
Thanks.
UPDATE :
I fixed the problem but created a file config/initializer/delayed_job.rb with
require 'delayed_job'
Delayed::Worker.backend = :active_record

Sometimes gems just refuse to install properly. I think what you should do is (assuming you have git installed, otherwise go here https://github.com/tobi/delayed_job and download delayed_job as a zip file)
take what he has in his lib folder and put it in yours. wherever you need to use his methods then do
in the top of those files
I checked this tutorial, it shows a way to setup in rails 3
it suggests using this in your gemfile
