Question

我有代码来编写文件来保存PDF然后将其上传到s3。我在dev中完美地工作了。但不是在制作中。

def upload_to_s3(pdf)
  save_path = "#{Rails.root}/tmp/pdfs/invoice_#{@invoice.id}.pdf"
  f = File.new(save_path, 'w:ASCII-8BIT')
  f.write(pdf)
  uploader = InvoiceUploader.new
  File.open(save_path) { |file| uploader.store!(file) }
  @invoice.update(pdf: uploader.url)
  File.delete(save_path)
  uploader.url
end

堆栈追踪：

错误消息明确指出：

Errno :: ENOENT（没有这样的文件或目录@ rb_sysopen - /home/deploy/reputation/releases/20180401031049/tmp/pdfs/invoice_2.pdf）：...

预先在生产中创建目录/home/deploy/reputation/releases/20180401031049/tmp/pdfs/。由于它是动态的（取决于发布日期时间），最好在ruby代码中创建它：

save_dir = "#{Rails.root}/tmp/pdfs/"
Dir.mkdir(save_dir)

save_path = ...

将PDF保存到文件
