pinexq-client 1.7.3

A hypermedia-based client for the DataCybernetics PinexQ platform.

PineXQ Python Client

A hypermedia-based client for the DataCybernetics PineXQ platform.

This module contains the submodules:

• core: A generic hypermedia client (HC) to work with siren hypermedia APIs Siren on GitHub

• job_management: Specialized HC-object (HCO) implementations for the PinexQ Job-Management API (JMA).

Installation

Install from PyPI by running

pip install pinexq-client

Setup the Client

The hypermedia client uses HTTPX as a backend. To access the API you need to provide a pre-configured HTTPX-client with a valid API key for authentication. From The API key the user and permissions are derived so do not share the API key and store it securely.

To initialize the client parts must be supplied:

• The API key (as header)
• The API host as URL with port if required

from httpx import Client

from pinexq.client.job_management.enterjma import enter_jma
from pinexq.client.job_management.hcos.entrypoint_hco import EntryPointHco

client = Client(
    base_url="https://myapihost.com:80",
    headers={'x-api-key': '<SECRET_PAT>'}
)

# the client is now ready to be passed to function entering the API
entrypoint: EntryPointHco = enter_jma(client)

Using the API

Job-Management Interface

There is a convenience layer wrapping job-management-specific objects in interface classes for ease of use.

from pinexq.client.job_management.tool import Job
from pinexq.client.job_management.model import JobStates

job = (
    Job(client)
    .create(name="JobName")
    .select_processing(processing_step="step_function_name")
    .configure_parameters(param_name="value")
    .start()
    .wait_for_completion()
)
result = job.get_result()

Raw Hypermedia API

In the spirit of a hypermedia API you can also use low level calls to navigate the API, e.g. when features are not yet exposed in the convenience wrapper.

from pinexq.client.job_management.enterjma import enter_jma
from pinexq.client.job_management.hcos.entrypoint_hco import EntryPointHco
from pinexq.client.job_management.model import CreateJobParameters, SetJobTagsParameters

entrypoint: EntryPointHco = enter_jma(client)
# Get to jobs root
job_root = entrypoint.job_root_link.navigate()
# Create a new job
parameters = CreateJobParameters(name="Test Job")
job = job_root.create_job_action.execute(parameters).navigate()
# Edit the job's tags
job.edit_tags_action.execute(SetJobTagsParameters(tags=["test", ]))
