1.命令行指定环境

我们知道正常的django项目都是有多个环境的配置的，在启动时需要指定启动环境，如：

python manage.py runserver --settings=myapp.settings.test

其中的myapp.settings.test对应你的应用的目录级别，test对应的就是test.py

2.Visual Studio Code指定环境

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Django",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder}/manage.py",
            "args": [
                "runserver",
                "--noreload",
                "--settings=myapp.settings.test"
            ],
            "django": true
        }
    ]
}
