Currently , I have deployed my django project on google app engine. I need to run python manage.py migrate command so that auth_user table should b

If I get it right, your app runs on App Engine (sandboxed environment) and uses Cloud SQL.

1) Configure your database in settings.py as you can see below.

if os.getenv('SERVER_SOFTWARE', '').startswith('Google App Engine'):
    # Running on production App Engine, so use a Google Cloud SQL database.
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'HOST': '/cloudsql/project-id:instance-name',
            'NAME': 'database-name',
            'USER': 'root',
        }
    }
elif os.getenv('SETTINGS_MODE') == 'prod':
    # Running in development, but want to access the Google Cloud SQL instance in production.
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'INSTANCE': 'cloud-sql-instance-ip-address',
            'NAME': 'database-name',
            'USER': 'root',
            'PASSWORD': 'password',
        }
    }
else:
    # Running in development, so use a local MySQL database.
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': 'database-name',
            'USER': 'username',
            'PASSWORD': 'password',
        }
    }

2) Set environment variable SETTINGS_MODE to prod (or do not set if you want to access your local MySQL server).

3) Run the below command from your machine.

$ SETTINGS_MODE=prod python manage.py migrate
