Examples on interacting with Events with GraphQL¶

Overview¶

An Event represents either a machine or a human generated thing. It typically has a bounding box associated with it, a score, and optionally a surprise level.

A collection of events with the same track_uuid represent a Track.

import requests
# This is the endpoint for the GraphQL API. On a production installation it might be http://<yourservername>/api .
API_URL = "http://localhost:4000/graphql"
# Put your auth token from login here
AUTH_TOKEN = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOjEsImlhdCI6MTY1NTkyMjI5NCwiZXhwIjoxNjU2NTI3MDk0fQ.6aEzi28x5s2jt7bvK2lURJD6Q-afKrf4DpYxofgJHjM"

import requests # This is the endpoint for the GraphQL API. On a production installation it might be http:///api . API_URL = "http://localhost:4000/graphql" # Put your auth token from login here AUTH_TOKEN = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOjEsImlhdCI6MTY1NTkyMjI5NCwiZXhwIjoxNjU2NTI3MDk0fQ.6aEzi28x5s2jt7bvK2lURJD6Q-afKrf4DpYxofgJHjM"

Changing an event identifier¶

To change the unique identifier for an event to another, use the changeEventsInTrack mutation.

In [2]:

def change_events_in_track(source_track_uuid: str, target_track_uuid: str):
    query = """ mutation
        changeEvents($source_track_uuid: String!, $target_track_uuid: String!) {
            changeEventsInTrack(source_track_uuid: $source_track_uuid, target_track_uuid: $target_track_uuid ) {
              success
              message
            }
        }
    """

    variables = {"source_track_uuid": source_track_uuid, "target_track_uuid": target_track_uuid}
    reply = (requests.post(API_URL, headers={'Authorization': f'Bearer {AUTH_TOKEN}'},
                             json={'query': query, 'variables': variables}).json())
    print(reply)

def change_events_in_track(source_track_uuid: str, target_track_uuid: str): query = """ mutation changeEvents($source_track_uuid: String!, $target_track_uuid: String!) { changeEventsInTrack(source_track_uuid: $source_track_uuid, target_track_uuid: $target_track_uuid ) { success message } } """ variables = {"source_track_uuid": source_track_uuid, "target_track_uuid": target_track_uuid} reply = (requests.post(API_URL, headers={'Authorization': f'Bearer {AUTH_TOKEN}'}, json={'query': query, 'variables': variables}).json()) print(reply)
