Question

在我的Ruby on Rails应用程序中，我试图在电子邮件中嵌入徽标以便内联显示，但由于某种原因它没有出现（请参见下图）。我试图按照Stack Overflow问题What is the right way to embed image into email using Rails?上的答案进行操作，但无法使其工作。

我的邮件如下：

class UserEmails < ApplicationMailer
  def send_email(email, unsubscribe)
    @url  = 'http://localhost:3000/users/login'
    @email = email
    @unsubscribe = unsubscribe
    attachments.inline['logo.jpg'] = File.read('app/assets/images/logo.jpg')
    mail(from: "#{@email.from_name} <#{@email.account.email}>", to: @email.to, cc: @email.cc, bcc: @email.bcc, subject: @email.subject)
  end
end

我的电子邮件视图：

<!DOCTYPE html>
<html>
  <head>
    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
  </head>
  <body>
    <h1><%= @email.subject %></h1>
    <p>

    <p>
        To
      <%= image_tag attachments['logo.jpg'].url %>
      <%= link_to "Unsubscribe", settings_unsubscribe_url(id: @unsubscribe) %>
  </body>
</html>

有人能告诉我为什么这不起作用吗？

Ruby on Rails：为什么我的图像不会在电子邮件中显示为内嵌？
