Question

我想在创建并支付新订阅时向客户发送确认电子邮件，但我的Django电子邮件功能导致服务器错误（500）。服务器的错误日志没有提供任何详细信息，但我已将错误隔离到views.py中的subscription.send_subscription_email()函数。

我错过了send_subscription_email()中的内容吗？

Dear Customer,

Thank you for creating your first subscription! Just to confirm, your weekly deliveries will be sent to {{ apartment }}, and your first delivery will arrive on {{ first_delivery_date }}. After that, you'll receive deliveries every Monday until you cancel your subscription. Currently, you have selected the option {{ weekly_plan }}, but you can upgrade or downgrade at any time. We'll be sure to notify you once your first delivery arrives.

If anything looks incorrect, please email us at info@gather-food.us or update your subscription at http://www.gather.kitchen/profile/.

Enjoy!
Addison
