Rails 5.2.0 images.attach导致InvalidSignature错误

标签： rails-activestorage ruby-on-rails-5.2

我正在升级到Rails 5.2.0并尝试使用ActiveStorage来保存数据Feed中的图像。在config.active_storage.service = :local我有has_many_attached :images，模型有storage.yml，:local有默认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 设置，控制器操作有

listing.images.attach(pics)

我的代码挂断了这一行

ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature出现此错误：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

我的代码：

tomb$ rake update:listing_images --trace
    ** Invoke update:listing_images (first_time)
    ** Invoke environment (first_time)
    ** Execute environment
    ** Execute update:listing_images

答案 0 :(得分：3)

您将Rets::Parser::Multipart::Part个对象数组传递给ActiveStorage::Attached::Many#attach。它不知道如何处理它们。

对于每张照片，请使用IO和文件名调用#attach：

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