我正在尝试学习 Aws cloud Formation ,我正在尝试创建 VPC,如图所示。它包含三个公共子网、私有子网、natgateway 和 Internetgateway,以及公共和私有路由表。我试图通过云形成来实现它,但获得弹性 IP 的例外。
我已经创建了模板,但是当我尝试在云形成上创建堆栈时,出现错误
"The elastic-ip ID 'xx.xxx.xx.xxx' is malformed (Service: AmazonEC2; Status Code: 400; Error Code: InvalidElasticIpID.Malformed; Request ID: 2e3a9f8c-5a7e-482e-869c-8a0e46a08f27; Proxy: null)"

我正在尝试通过 Django Shell 保存我的模型的值。我是 Django 的初学者。我已经装箱了三个模型。我在模型中逐一插入值。我首先创建了部门并插入了所有部门值。创建了学生并插入了所有与学生相关的值。现在我尝试在包含两个外键 StudentId 和 dept id 的课程中插入值。如何使用 Django Shell 为 Student 模型插入值。
