Question

我在非rails应用程序中使用“mail”gem发送电子邮件：

    [1] pry(TicketMailer)> mail.body
    => #<Mail::Body:0x00007f6f48823890
     @ascii_only=true,
     @boundary=nil,
     @charset="US-ASCII",
     @encoding="7bit",
     @epilogue=nil,
     @part_sort_order=["text/plain", "text/enriched", "text/html", "multipart/alternative"],
     @parts=
      [#<Mail::Part:70057967292360, Multipart: false, Headers: <Content-Type: application/pdf; filename="tickets.pdf">, <Content-Transfer-Encoding: binary>, <Content-Disposition: attachment; filename="tickets.pdf">, <Content-ID: <fdsfs343243243432@fdsafdsfds.mail>>>],
     @preamble=nil,
     @raw_source=
      "<!DOCTYPE html>\n<html>\n  <head>\n    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />\n  [...........]  </body>\n</html>">
    [2] pry(TicketMailer)>

调试：

UPDATE user_credits
CROSS JOIN (SELECT SUM(credits) AS total
            FROM user_credits)
SET credits = credits + X * credits / total

然而，一封电子邮件带有空身。为什么以及如何解决这个问题？

宝石“邮件”忽略了它的身体
