У меня есть приложение с видом API для отдыха, которое я использую для отправки электронных писем.Однако в настоящее время он отправляет только текстовое электронное письмо, поэтому мне нужно знать, как его изменить и заставить отправлять HTML.Ниже приведен код:

Allows you to specify IP addresses and associated "api_key"s to prevent others from using your app.
Storage and Manipulation methods will check for this "api_key" in the POST/GET params.
Retrieval methods don't use it (however you could enable them to use it, but maybe rewrite so you have a "read" key and a "write" key to prevent others from manipulating your data).
Set "AUTH = False" to disable (allowing anyone use your app and CRUD your data).
