时间：2021-01-08 20:40:54

have issue with code that rise just now but work before i got this code:

有问题的代码刚刚上升，但在我得到这段代码之前工作：

  1. Controller

    调节器

    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

    end

    结束

  2. Model

    模型

class Assets < ActiveRecord::Base

class Assets 

  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

now its return me this error:

现在它给我这个错误：
