rails-activestorage - Rails 5.2.0 images.attach 导致 InvalidSignature 错误

Question

我正在升级到 Rails 5.2.0 并尝试使用 ActiveStorage 来保存数据馈送中的图像。在 development.rb我有 config.active_storage.service = :local并且模型有 has_many_attached :images和 storage.yml有默认 :local设置和 Controller Action 有

def listing_params
      params.require(:listing).permit(:beds, :baths, :price, :parking, :description, :active, :prop_type, :latitude, :longitude, :address, :city, :city_id, :state, :state_id, :zip, :lo_name, :la_fname, :la_lname, :la_phone, :la_email, :mlsid, :cp, :st_number, :st_suffix, :baths_full, :baths_half, :status, :modtime, :st_name, :featured, :school_id, :picture_count, :parking_type, images: [])
    end

我的代码在这条线上挂了
listing.images.attach(pics)出现此错误: ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature
我的代码:

def perform
    require 'aws-sdk-s3'
    require 'rets'

    client = Rets::Client.new({
      login_url: LOGIN_URL,
      username: LOGIN,
      password: PASSWORD,
      version: VERSION
     })

    begin
      client.login
    rescue => e
      puts 'Error: ' + e.message
      exit!
    end

    p "Logged in"

    Listing.find_each do |listing|
      mlsid = listing.mlsid
      photos = client.objects '*', {
         resource: 'Property',
         object_type: 'Photo',
         resource_id: mlsid
       }
       p "about to attempt to attach #{photos.count} images to listing#{listing.id}"
      pics = []
      photos.each do |data|
        pics << data.body
      end
      listing.images.attach(pics)
      puts "#{photos.count} images attached to listing##{listing.id}"
    end
  end  

使用 --trace 运行后的完整错误:

tomb$ rake update:listing_images --trace
    ** Invoke update:listing_images (first_time)
    ** Invoke environment (first_time)
    ** Execute environment
    ** Execute update:listing_images
    Cookie#domain returns dot-less domain name now. Use Cookie#dot_domain if you need "." at the beginning.

Answer 1

您正在传递一个数组 Rets::Parser::Multipart::Part反对 ActiveStorage::Attached::Many#attach .它不知道如何处理它们。

每张照片，请调用#attach带有 IO 和文件名:

photos.each_with_index do |photo, index|
  listing.images.attach(io: StringIO.new(photo.body), filename: "photo-#{index + 1}.png")
end
