Django在post_save上使用模板发送电子邮件

Question

当用户将新数据提交到我们的网站时，我正在尝试向管理员发送电子邮件。我们使用Django作为后端，使用Vue作为前端，尽管这可能并不重要。这是代码：

@receiver(post_save)
def send_update(sender, created, **kwargs):
    if created:
        data=kwargs['instance']
        try:
            if data.admin_approved == False:
                print("point 1 reached")
                name = data.submitted_by_name
                body = data.body
                content_type = str(sender).split(".")[2][:-2]
                print("point 2 reached")
                link = "https://link_to_website.com" + content_type.lower()
                subject = "New " + content_type + " submitted"
                print("point 3 reached")
                from_email = "NoReply@web_site.com"
                to_email = "my_email@address.com"
                print("pre-html point reached")
                html_message = get_template('./email/template.html')
                text_message = get_template('./email/textplate.txt')
                data = {
                        'user_name': name,
                        'submission': data.body,
                        'type': content_type,
                        'link': link,
                        'body': body
                    }
                content_text = text_message.render(data)
                content_html = html_message.render(data)
                print("ready to send email!")
                msg = EmailMultiAlternatives(subject, content_text, from_email, [to_email])
                msg.attach_alternative(content_html, "text/html")
                msg.send()
        except:
            print("Data was not submitted by an non-admin user.")

包含try / except，以便直接通过django管理页面提交的数据不会触发电子邮件功能。

该功能工作到“到达pre-html点”为止，我猜问题出在msg和msg.send（）内，但是我没有收到任何错误功能。

感谢您的帮助！
