Phusion Passenger 错误“未知密钥：通过”
我的 Rails 应用程序在本地测试服务器上运行良好，但是当我部署到生产（Passenger）服务器时，出现以下错误：
Error message:
Unknown key(s): through
Exception class:
ArgumentError
为什么会发生这种情况？该代码不可能存在固有缺陷，因为在开发服务器上一切正常。有问题的代码非常简单：
class PageEvent < Event
belongs_to :page, :through => :calendar
end
where
class Event < ActiveRecord::Base
belongs_to :calendar, :polymorphic => true
end
和
class Calendar < ActiveRecord::Base
has_many :events, :dependent => :destroy, :inverse_of => :calendar, :as => :calendar, :class_name => "SpecialEvent"
end
My rails application runs fine on my local testing server, but when I deploy to my production (Passenger) server, I get the following error:
Error message:
Unknown key(s): through
Exception class:
ArgumentError
Why might this be happening? The code can't be inherently flawed, since everything works fine on the development server. The offending piece of code is very simple:
class PageEvent < Event
belongs_to :page, :through => :calendar
end
where
class Event < ActiveRecord::Base
belongs_to :calendar, :polymorphic => true
end
and
class Calendar < ActiveRecord::Base
has_many :events, :dependent => :destroy, :inverse_of => :calendar, :as => :calendar, :class_name => "SpecialEvent"
end

我不能说它似乎在开发中工作，但没有

I can't say what is happening that it appears to be working in dev, but there is no
