Question

CarrierWave的新手，已经爱上了它，比Paperclip好多了。 Rails 3.2.1

我成功使用本地存储，但现在尝试转移到S3并在_url方法（或数据库列）上出现奇怪的错误

ArgumentError：参数数量错误（2表示1）

这是我的上传者：

class PictureUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :fog
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
  process :resize_to_limit => [200, 200]
  def extension_white_list
    %w(jpg jpeg gif png)
  end
end

本地存储一切正常，S3 / fog将文件上传并调整为S3，我可以在桶中看到它;字段/ field_url方法似乎存在问题，它给出了错误（2为1）

我设置了非公开的s3：

CarrierWave.configure do |config|
  config.fog_credentials = {
  :provider               => 'AWS',       # required
  :aws_access_key_id      => 'xxx',       # required
  :aws_secret_access_key  => 'yyy',       # required
  :region                 => 'eu-west-1'  # optional, defaults to 'us-east-1'
 }
 config.fog_directory  = 'attachprod'                     # required
 config.fog_public     = false                                   # optional, defaults to true
end

这在我看来：

 <%= image_tag current_user.profile.picture_url %>

完整追踪：

任何想法，在任何地方找不到多少？
