Plone powered provider for fhirpath

Project description

Egg Status Travis Build Status Test Coverage Python Versions Latest Version License https://img.shields.io/badge/code%20style-black-000000.svg

Background (collective.fhirpath)

fhirpath implementation in Plone, essential battery included, ready to use.

Installation

Install collective.fhirpath by adding it to your buildout:

[buildout]
...
eggs +=
    collective.fhirpath

and then running bin/buildout

From Plone controlpanel in the addon settings, install collective.fhirpath.

How It Works

``FhirResource`` the fhirfield

Make sure this specialized field is used properly according to plone.app.fhirfield documentation.

Make field indexable

A specilized Catalog PluginIndexes is named FhirFieldIndex is available, you will use it as like other catalog indexes.

Example:

<?xml version="1.0"?>
<object name="portal_catalog" meta_type="Plone Catalog Tool">
    <index name="organization_resource" meta_type="FhirFieldIndex">
        <indexed_attr value="organization_resource"/>
    </index>
</object>

Elasticsearch settings

Make sure elasticsearch has been configured accourding to collective.elasticsearch docs.

>>> result = result_query.first()
>>> isinstance(result, result_query._query.get_from()[0][1])
True

Use FHIRModelServiceMixin

For better performance optimization, you should use FHIRModelServiceMixin to response FHIRModel, FhirFieldValue object efficiently.

Example 1:

>>> from plone.restapi.services import Service
>>> from collective.fhirpath.utils import FHIRModelServiceMixin
>>> class MyFHIRGetService(FHIRModelServiceMixin, Service):
....     """ """
....     def reply(self):
....        # do return bellow's types of data
....        # could be ``dict`` type data
....        # could be instance of ``FHIRAbstractModel`` derrived class.
....        # could be instance of ``plone.app.fhirfield.FhirResourceValue`` derrived class.
....        # or self.reply_no_content()

configuration

This product provides three plone registry based records fhirpath.es.index.mapping.nested_fields.limit, fhirpath.es.index.mapping.depth.limit, fhirpath.es.index.mapping.total_fields.limit. Those are related to ElasticSearch index mapping setup, if you aware about it, then you have option to modify from plone control panel (Registry).

REST Client Examples

Getting single resource, here we are getting Patient resource by ID.

Example(1):

>>> response = admin_session.get('/@fhir/Patient/19c5245f-89a8-49f8-b244-666b32adb92e')
>>> response.status_code
200
<BLANKLINE>
>>> response.json()['resourceType'] == 'Patient'
True
<BLANKLINE>
>>> response = admin_session.get('/@fhir/Patient/19c5245f-fake-id')
>>> response.status_code
404
<BLANKLINE>

Search Observation by Patient reference with status condition. Any observation until December 2017 and earlier than January 2017.

Example(2):

>>> response = admin_session.get('/@fhir/Observation?patient=Patient/19c5245f-89a8-49f8-b244-666b32adb92e&status=final&_lastUpdated=lt2017-12-31T00%3A00%3A00%2B00%3A00&_lastUpdated=gt2017-01-01T00%3A00%3A00%2B00%3A00')
>>> response.status_code
200
>>> response.json()["total"]
1
<BLANKLINE>

Add FHIR Resource through REST API

Example(3):

>>> import os
>>> import json
>>> import uuid
>>> import DateTime
>>> import time

>>> with open(os.path.join(FIXTURE_PATH, 'Patient.json'), 'r') as f:
...     fhir_json = json.load(f)

>>> fhir_json['id'] = str(uuid.uuid4())
>>> fhir_json['name'][0]['text'] = 'Another Patient'
>>> response = admin_session.post('/@fhir/Patient', json=fhir_json)
>>> response.status_code
201
>>> time.sleep(1)
>>> response = admin_session.get('/@fhir/Patient?active=true')
>>> response.json()["total"]
2

Update (PATCH) FHIR Resource the Patient is currently activated, we will deactive.

Example(4):

>>> patch = [{'op': 'replace', 'path': '/active', 'value': False}]
>>> response = admin_session.patch('/@fhir/Patient/19c5245f-89a8-49f8-b244-666b32adb92e', json={'patch': patch})
>>> response.status_code
204
<BLANKLINE>
