Dispatching objects.

Demoing class and instance dispatching

from py2http.service import run_app

if __name__ == '__main__':
    app.run()

Run that python file et then, somewhere else, do, for the demo/test:

import requests
from functools import partial


def mk_post_request(url, data=None):
    if data is None:
        return partial(mk_post_request, url)
    return requests.post(url, json=data)

datasets = mk_post_request("http://127.0.0.1:8080/datasets")

r = datasets(
    {"_obj_id": None, "_attr_name": None, "dataset_name": "apple"}
)

obj_id = r.json()
print(f"{obj_id=}")

r = datasets(
    {"_obj_id": obj_id, "_attr_name": "search", "query": "my query"}
)
assert r.json() == 'Searching apple for my query'

r = datasets(
    {"_obj_id": obj_id, "_attr_name": "store", "key": "my_key", "value": "my_value"}
)
assert r.json() == 'Storing my_value under my_key in apple'
