Paperclip在更新后突然抛出一个奇怪的错误

Question

我无法再在我的Rails应用程序中使用paperclip url呈现页面.我最近更新了我的宝石包.我正在使用Rails 3.2.8和Paperclip 3.1.4.我之前使用的是Paperclip 2.7.0.

我视图中失败的链接是:

ad.image.url(:medium)

我的广告模型包含以下声明:

Paperclip.interpolates :ad_subdomain do |attachment, style|
  attachment.instance.brand.subdomain
end

has_attached_file :image, 
                :default_url => '/images/blank.gif',
                :styles => { :medium => ["290x230>","jpg"],
                             :thumb => ["100x100>","jpg"] },
                :storage => :file,
                :path => "/mcp/ads/:style/:ad_subdomain/:basename.:extension"

抛出的错误是:

TypeError: wrong argument type Class (expected Module)

Answer 1

出于某种原因,我有:

:storage => :file

在我的声明中.这不起作用.如果你想使用文件系统,你只需完全省略存储行,它将是默认的.
