ActionMailer 呈现更多然后需要

ActionMailer renders more then needed

class UserMailer

def notification_email(user, msg_body, msg_count)
    @user = user
    @msg_body = msg_body
    mail(to: @user.email, subject: "New comments. #{msg_count}.")
  end

notification_email.html.erb

<!DOCTYPE html>
<html>
<head>
  <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
</head>
<body>
<h1>You have new comments </h1>
<p>
  <ul>
   <%= @msg_body.each do |msg| %>
    <li><a href="<%= msg %>"><%= msg %></a></li>
   <% end %>
  </ul>
</p>
</body>
</html>

对于消息正文,我传递给视图数组 msg_body。在 mailcatcher 中,我可以根据需要查看 href 列表。但我也看到列表后面的数组是纯文本。实在是看不懂从哪里来。

尝试将 <%= @msg_body.each do |msg| %> 更改为 <% @msg_body.each do |msg| %> - 从每个块中删除相等项
