我是 Rails 邮件程序的新手。我已经部署到heroku，并且电子邮件可以正常发送和接收。问题是没有一个邮件程序正在呈现视图。
情况并非总是如此。我一定是移动了对该连接至关重要的东西并断开了连接。您能告诉我如何将视图重新连接到邮件程序吗？
我在 Rails 3.2 上，这里是您可能需要回答的信息：
在邀请模型中：
after_create do |invitation|
InvitationMailer.delay.invitation_email(self)
end
在邮件中：
class InvitationMailer < ActionMailer::Base
helper ActionView::Helpers::UrlHelper
default from: "noreply@lumeo.com"
def invitation_email(invite)
@invitation = invite
mail(to: invite.recipient_email,
subject: "Invitation",
:template_path => 'mailers/invitation_email')
end
end
最后，视图位于视图/邮件中：
You are invited to join our beta!
<%= link_to 'Sign Up', signup_with_token_url(@invitation.token) %>
这条线的路由正确，并且像我过去测试过的那样工作，但是视图不再呈现在电子邮件的正文中......
