fhirpath 0.1.1

Quickstart (guillotina)

This quickstarter guide is based on guillotina and elasticsearch with extra guillotina_elasticsearch dependency. If don´t know about guillotina, have a look at their nice document. Add fhirpath and guillotina_elasticsearch in your project dependencies. Install fhirpath.providers.guillotina_app from your app configuration file.

we assume you configure elasticsearch_ service properly and have FHIR_ content types and latstly of course you know about FHIR_

Example: Add Contents:

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.providers.guillotina_app.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.providers.guillotina_app.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"
