刚刚出现的代码有问题，但在我得到这个代码之前就可以工作：

  1. 控制器

    def new
errors ||= Array.new
if params[:file].blank? 
  errors.push(I18n.t("errors.messages.file_error"))
end
if errors.length == 0 
 # begin
 # 
  binding.pry
    assetObject = Assets.new(:asset=>params[:file])
    assetObject.save!
    image = assetObject.asset.url(:small)
    imageExpBanner = assetObject.asset.url(:expBanner)
    data = OpenStruct.new({
      id: assetObject.id,
      uri: image,
      expBannerUri: imageExpBanner
    })
    @responseObject = OpenStruct.new({
      status: true,
      errors: [],
      code: API_CODE_ERRORS['Services']['Global']['success'],
      objectData: data
    })
    render :template => 'api/v1/general/assets/new' ,:handlers => [:rabl],:formats => [:json]
  #rescue => e
  #  binding.pry
  #  logger.error e
   # errors.push(I18n.t("errors.messages.file_size_error"))
  #  render :json => Api::Init.ShowErrorJson(API_CODE_ERRORS['Services']['Global']['file_size'],I18n.t("errors.messages.feelike.input_error"), errors).to_json
# end
else
  render :json => Api::Init.ShowErrorJson(API_CODE_ERRORS['Services']['Global']['formInputError'],I18n.t("errors.messages.feelike.input_error"), errors).to_json
end

    结尾

  2. 模型

资产类 < ActiveRecord::Base

  attr_accessible :asset,:asset_content_type, :asset_file_name, :asset_file_size

  has_attached_file :asset, :styles => { 
    :small => "150x150>" ,
    :expBanner => "620x184",
    :expBigImage => "304X304",
    :expSmallImage => "148X148",
    :storage => :s3,
    :s3_credentials => "#{Rails.root}/config/s3.yml",
    :path => "/uploads/:style/:id/:hash.:extension",
    :url  => :s3_eu_url ,
    :hash_secret => "longSecretString"
    }
    validates :asset, :attachment_presence => true
  validates_attachment_size :asset, :less_than => 10.megabytes
  validates_attachment_content_type :asset, :content_type => ['image/jpeg','image/gif', 'image/png']
end

现在它返回我这个错误：

现在它意味着什么类型错误 - 无法复制符号现在我尝试了几种方法修复并得到这个每次都需要帮助
