在view.py和serializer.py中 我已经提到了我尝试过的每一种发送电子邮件的方法，这就是为什么它如此混乱的原因。这些方法都不起作用。 即使是

create

方法也根本不调用

这是显示在我的api管理员我想改变保存按钮文本发送

我不想创建模型。它是为了在admin i所需模型上显示此文件而创建的

也不希望将文件保存在文件夹中。这就是节约

filefield只需打开文件，然后在我的硬编码电子邮件地址上，当我按下“保存/发送”按钮时，以电子邮件的形式发送该文件

您可以在不需要模型的地方创建自定义管理页面。解决了这个问题

---

现在，当您创建自定义页面时，在视图中，您可以简单地使用sendgrid提供的python API并执行您想要实现的任何操作。以下是相同的示例。

如果您想发送带有附件的邮件，您已经在此处询问了更多详细信息

谢谢。Vaibhav Singhwhy my Overrided create不在View.py和serializer.py中工作您附加的屏幕截图是您的ModelAdmin视图，它不会调用您的Emailviewset。我不在django中工作，我在django Rest框架中工作。
