（我对Rails相对较新）
我有一个文件（Ruby）我正在通过Ironworker运行/上传，目前正在使用MySql（activeRecord）作为数据库。 ALl工作正常，但我们现在需要一个新的（附加）模型，它将使用Mongoid，它也将包含在我们上传到IronWorker的代码中。 当我将以下行merge_gem'mongoid'包含在我的IronWorker文件中时，我得到：
DEPRECATION WARNING：不再需要为属性方法指定空前缀/后缀。如果在调用
define_attribute_methods时尚未定义方法的未加前缀/后缀的版本，则会自动定义该版本。 （在/usr/lib/ruby/gems/1.9.1/gems/activerecord-3.1.6/lib/active_record/attribute_methods/read.rb:9中从块中调用）

首先，iron_worker gem暂时弃用了。如果可以，请将您的代码更新为iron_worker_ng gem（https://github.com/iron-io/iron_worker_ruby_ng）。这个动作将解决合并宝石的99.9％问题（这是编写新宝石的主要原因）
可能原因：宝石版本不匹配，多为铁轨宝石。了activerecord /的ActiveSupport /等
尝试：
gem 'mygem', '=0.1.2'
