fhirpath-guillotina 0.2.0

A guillotina framework powered fhirpath provider.

Introduction

A guillotina framework powered fhirpath provider. Full battery included to use fhirpath more efficiently.

If you don’t know about FHIR® and HL7®, Please have a look here.

Quickstart

1. Make sure fhirpath_guillotina is added as addon in your guillotina configure file.

2. Make sure elasticsearch server configured properly.

3. Make sure you have FHIR resource contenttypes registered (see example bellow).

4. Make sure you have FHIR resources mapping (correct version) for elasticsearch.

Example: Add Contents:

>>> from fhirpath_guillotina.field import FhirField

class IOrganization(IFhirContent, IContentIndex):
    index_field(
        "organization_resource",
        type="object",
        field_mapping=fhir_resource_mapping("Organization"),
        fhirpath_enabled=True,
        resource_type="Organization",
        fhir_version=FHIR_VERSION.DEFAULT,
    )
    index_field("org_type", type="keyword")
    org_type = TextLine(title="Organization Type", required=False)
    organization_resource = FhirField(
        title="Organization Resource", resource_type="Organization", fhir_version="R4"
    )


@configure.contenttype(type_name="Organization", schema=IOrganization)
class Organization(Folder):
    """ """

    index(schemas=[IOrganization], settings={})
    resource_type = "Organization"

Example Search:

>>> from guillotina.component import query_utility
>>> from fhirpath.interfaces import ISearchContextFactory
>>> from fhirpath.interfaces import IFhirSearch
>>> search_context = query_utility(ISearchContextFactory).get(
...    resource_type="Organization"
... )
>>> search_tool = query_utility(IFhirSearch)
>>> params = (
...     ("active", "true"),
...     ("_lastUpdated", "2010-05-28T05:35:56+00:00"),
...     ("_profile", "http://hl7.org/fhir/Organization"),
...     ("identifier", "urn:oid:2.16.528.1|91654"),
...     ("type", "http://hl7.org/fhir/organization-type|prov"),
...     ("address-postalcode", "9100 AA")
... )
>>> fhir_bundle = await search_tool(params, context=search_context)
>>> fhir_bundle.total == len(fhir_bundle.entry)

Example FhirPath Query:

>>> from fhirpath.interfaces import IElasticsearchEngineFactory
>>> from guillotina.component import query_utility
>>> from fhirpath.enums import SortOrderType
>>> from fhirpath.fql import Q_
>>> from fhirpath.fql import T_
>>> from fhirpath.fql import V_
>>> from fhirpath.fql import sort_
>>> engine = query_utility(IElasticsearchEngineFactory).get()
>>> query_builder = Q_(resource="Organization", engine=engine)
>>> query_builder = (
...        query_builder.where(T_("Organization.active") == V_("true"))
...        .where(T_("Organization.meta.lastUpdated", "2010-05-28T05:35:56+00:00"))
...        .sort(sort_("Organization.meta.lastUpdated", SortOrderType.DESC))
...        .limit(20)
...    )
>>> query_result = query_builder(async_result=True)
>>> result = query_result.fetchall()
>>> result.header.total == 100
True
>>> len(result.body) == 20
True
>>> async for resource in query_result:
...     assert resource.resource_type == "Organization"
