錯誤紅寶石 - 代碼「類型錯誤不能DUP符號」

有代碼的問題是剛剛興起，但現在我得到這個代碼之前工作：錯誤紅寶石 - 代碼「類型錯誤不能DUP符號」

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

末

模型

個

類資產<的ActiveRecord :: Base的

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

現在它的回報我這個錯誤：

現在什麼劑量它意味着類型錯誤 - 不能DUP符號現在我嘗試幾種方法解決在而得到這個每次都需要在這個

請你也可以發佈你的代碼與'has_attached_file'部分的代碼綁定 – Aleks 2013-03-28 09:41:11

幫助發現問題是有

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"
