python 3.10 postgresql 14 or higher
- create a virtual environment with python 3.10
- install requirements in the virtual environment with
- setup a postgresql database and provide the following environment variables
``` SQL_ENGINE="django.db.backends.postgresql" SQL_DATABASE="name_of_your_database" SQL_USER="name_of_your_user" SQL_PASSWORD="pw_of_your_user" SQL_HOST="localhost" SQL_PORT="postgresql port, usually 5434"
# replace 'localhost' by the name of the container if using docker CELERY_BROKER_URL="redis://localhost:6379/0" CELERY_RESULT_BACKEND="redis://localhost:6379/0"
- run migrations
- run the server
- visit the webapp at 127.0.0.1:8000/oemof
In order to simulate a scenario from a datapackage you should place datapackages in the django_oemof_api/data/oemof folder.
One this is done, open a new terminal with the same virtual environment and make sure you provide those two environment variables as well
``` CELERY_BROKER_URL="redis://localhost:6379/0" CELERY_RESULT_BACKEND="redis://localhost:6379/0"
``` Then start the celery worker with
`
celery -A django_oemof_api.celery worker --loglevel=info -E
`
Finally, you can send a post request from a third terminal
``` import requests import json
HOST = "http://127.0.0.1:8000" SIMULATE_URL = f"{HOST}/oemof/simulate"
- payload = {
- "scenario": "<name of a scenario datapackage within data/oemof folder>", "parameters": json.dumps({"some": "paremeters"}),
}
- with requests.session() as client:
- req = client.post(
- SIMULATE_URL, data=payload,
) answer = json.loads(req.text) print(f"{SIMULATE_URL}}?task_id={answer['task_id']}")
