end

It works perfectly, but I'm trying to return the user's email and I tried this: 它工作正常，但是我试图返回用户的电子邮件，并且我尝试了以下操作：

def mailboxer_email(object)
  return "#{User.email}"

  return object.email

Answer 1

This method solved it, it was just passing email without " : " 这种方法解决了它，它只是通过不带“：”的电子邮件

def mailboxer_email(object)
  return email  # instead of return :email
end
