使用 appengine "django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable"在

Question

我正试图在谷歌云上部署我自己的django应用程序。我正在遵循此文档由谷歌云部署该应用程序。我已经根据谷歌提供的示例应用程序的settings.py文件更改了我的应用程序的settings.py文件。

我按照相同的文档创建了一个Django环境文件作为Secret Manager机密。它的格式是

echo DATABASE_URL=postgres://DATABASE_NAME:DATABASE_USER_PASSWORD@//cloudsql/PROJECT_ID:REGION:INSTANCE_ID/CRRathod > .env
echo GS_BUCKET_NAME=my-portfolio-361305_crrathod-bucket >> .env
echo SECRET_KEY=$(cat/dev/urandom | LC_ALL=C tr -dc '[:alpha:]'| fold -w 50 | head -n1) >> .env

在输入下一个命令作为文档python manage.py makemigrations后，我在中收到了错误

(env) C:Program Files (x86)GoogleCloud SDKPortfolio-blog>python manage.py makemigrations

经过多次尝试，我还是解决不了这个错误。请帮我谢谢

Answer 1

我已经通过从我的秘密管理器文件(即.env文件(中删除一些额外的空间来解决了这个问题正如我之前在问题中提到的，我的秘密经理代码是

echo DATABASE_URL=postgres://DATABASE_USERNAME:DATABASE_USER_PASSWORD@//cloudsql/PROJECT_ID:REGION:INSTANCE_ID/CRRathod > .env
echo GS_BUCKET_NAME=my-portfolio-361305_crrathod-bucket >> .env
echo SECRET_KEY=$(cat/dev/urandom | LC_ALL=C tr -dc '[:alpha:]'| fold -w 50 | head -n1) >> .env

我把它改成了

echo DATABASE_URL=postgres://DATABASE_USERNAME:DATABASE_USER_PASSWORD@//cloudsql/PROJECT_ID:REGION:INSTANCE_ID/CRRathod>.env
echo GS_BUCKET_NAME=my-portfolio-361305_crrathod-bucket>>.env
echo SECRET_KEY=$(cat/dev/urandom | LC_ALL=C tr -dc '[:alpha:]'| fold -w 50 | head -n1)>>.env

刚刚删除了所有额外的空间

然后将来自终端的密钥值设置为set SECRET_KEY=my_secret_key_value
