ruby-on-rails csv yaml

Ruby on rails 作业延迟时出错。不能'；t解析YAML,ruby-on-rails,csv,yaml,delayed-job,Ruby On Rails,Csv,Yaml,Delayed Job,我通过以下代码将csv文件传递给延迟作业 csv_text = IO.read(params[:emails_import].tempfile.to_path, :encoding => 'UTF-8').gsub(" ", "") csv_text = csv_text.gsub("\n\n", "\n") Delayed::Job.enqueue ImportContact.new(@list.id, csv_text), :queue => "import-list-#{@li

我通过以下代码将csv文件传递给延迟作业

csv_text = IO.read(params[:emails_import].tempfile.to_path, :encoding => 'UTF-8').gsub(" ", "")
csv_text = csv_text.gsub("\n\n", "\n")
Delayed::Job.enqueue ImportContact.new(@list.id, csv_text), :queue => "import-list-#{@list.id}"

我通过foreman收到以下错误消息。知道是什么导致了这个问题吗？我认为错误可能在csv文件中，但我不确定问题的原因

当我运行bundle exec rake jobs:work
时，一切都正常进行，这让我相信YAML对您导入的文件进行编码或解码的方式存在问题
特别是，我会参加竞选
yaml = Delayed::Job.find(121).handler
File.open('job-121.yml', 'w') { |f| f.write(yaml) }

并检查第6709行第4列周围的文件
但是，现在可能是时候建议您将文件存储在S3之类的文件中，并将URL传递给ImportContact
worker，而不是整个CSV文本。这将缓解当前遇到的问题，并帮助您避免数据库因庞大的文本列而膨胀。
为什么要用如此大量的csv数据？如果它以上传文件的形式出现在您面前，为什么不将其保留为该格式，并让您正在排队的作业在将其传递到ImportContact实例之前进行转换？在独立于延迟的作业/队列运行作业时，您是否也会遇到同样的问题？这在调试问题时非常有用最后，我将csv文件切成小块，这有助于减少反序列化问题。
yaml = Delayed::Job.find(121).handler
File.open('job-121.yml', 'w') { |f| f.write(yaml) }
