Error: Please define stage 'create_pg_db' in your Zappa settings

Question

Intro: I am deploying a django app to AWS lambda severlessly using zappa. My RDS instance has a postgres database. I am watching rich jones djangocon video on how to deploy django app severlessly using zappa. So far I have managed to reach the part where I need to add a database to my project. I have already done pip install zappa-django-utils and added it to my INSTALLED_APPS. Now when I try to run

zappa manage create_pg_db production I get the error:

Error: Please define stage 'create_pg_db' in your Zappa settings.

I even tried zappa manage create_pg_db I am still getting the same error

Below is how my zappa_settings.json file looks:

{
    "production": {
        "aws_region": "us-east-1",
        "django_settings": "Cool.settings",
        "profile_name": "default",
        "project_name": "cool",
        "runtime": "python3.6",
        "s3_bucket": "cool-7dsfsdf5",
        "project_directory": "/tmp/code",
        "slim_handler": true,
        "vpc config": {
            "SubnetIds": [
                "subnet-3132ss13b",
                "subnet-321321319",
                "subnet-2c2313223",
                "subnet-5ljlkjljd",
                "subnet-132121357",
                "subnet-f925f9c7"
            ],
            "SecurityGroupIds": [
                "sg-a9asdasd"
            ]
        }
    },
    "production_ap_northeast_1": {
        "aws_region": "ap-northeast-1",
        "extends": "production"
    },
    "production_ap_northeast_2": {
        "aws_region": "ap-northeast-2",
        "extends": "production"
    },
    ... All regions..
}

How do I define stage create_pg_db in your Zappa settings. Does anyone know the steps ahead of this.

You only have one stage defined which is called production. If you want to name your stage create_pg_db then it would like this:

{
    "create_pg_db": {
        "aws_region": "us-east-1",
        "django_settings": "Cool.settings",
        "profile_name": "default",
        "project_name": "cool",
        "runtime": "python3.6",
        "s3_bucket": "cool-7dsfsdf5",
        "project_directory": "/tmp/code",
        "slim_handler": true,
        "vpc config": {
            "SubnetIds": [
                "subnet-3132ss13b",
                "subnet-321321319",
                "subnet-2c2313223",
                "subnet-5ljlkjljd",
                "subnet-132121357",
                "subnet-f925f9c7"
            ],
            "SecurityGroupIds": [
                "sg-a9asdasd"
            ]
        }
    },
    "production_ap_northeast_1": {
        "aws_region": "ap-northeast-1",
        "extends": "production"
    },
    "production_ap_northeast_2": {
        "aws_region": "ap-northeast-2",
        "extends": "production"
    },
    ... All regions...

    "production": {
        "aws_region": "us-east-1",
        "django_settings": "Cool.settings"
    ... MORE settings...    
}

At the end you can add more stages and then use the stage for your deployment. For example, you can have a develop stage that deploys your code to a development environment and a production stage that deploys your code to the production environment.
