fhir-core 1.1.10

Installation

Just a simple pip install fhir-core. But if you want development version, just clone from https://github.com/nazrulworld/fhir-core and pip install -e .[dev].

Usages

Example: 1: This example creates an Organization class with some of its attributes (id, active, name, address):

>>> from typing import List
>>> from pydantic import Field
>>> from fhir_core.fhirabstractmodel import FHIRAbstractModel
>>> from fhir_core.types import IdType, BooleanType, StringType
>>> data = {
...     "id": "f001",
...     "active": True,
...     "name": "Acme Corporation",
...     "address": ["Road 10": "Acme corporation", "2390", "USA"}]
... }
>>> class Organization(FHIRAbstractModel):
...     __resource_type__ = "Organization"
...     id: IdType = Field(None, title="Id", alias="id", json_schema_extra={"element_property": True})
...     active: BooleanType = Field(None, title="Active", alias="active", json_schema_extra={"element_property": True})
...     name: StringType = Field(None, title="Name", alias="name", json_schema_extra={"element_property": True})
...     address: ListType[StringType] = Field(None, title="Address lines", alias="address", json_schema_extra={"element_property": True})
...
...     @classmethod
        def elements_sequence(cls):
            return ["id", "active", "name", "address"]
...
>>> org = Organization.model_validate(data)
>>> org.active is True
True
>>> org_json_str = org.model_dump_json()
>>> Organization.model_validate_json(org_json_str).model_dump() == org.model_dump()
True
