FHIRPrimitiveModel

Path: fhircraft.fhir.resources.base.FHIRPrimitiveModel

FHIRPrimitiveModel(__value: Any | None = None, **data)

Bases: FHIRBaseModel

Base class for FHIR primitive types.

FHIR primitives are represented as Pydantic models with a single value field that holds the actual primitive value. This design allows us to attach extensions to primitive values while still treating them as simple types in most contexts.

Parameters:

Name	Type	Description	Default
value	Any | None	The actual value	None

Source code in fhircraft/fhir/resources/base.py

def __init__(self, __value: Any | None = None, **data):
    if __value is not None:
        data.setdefault("value", __value)
    super().__init__(**data)

FHIRSliceModel

Path: fhircraft.fhir.resources.base.FHIRSliceModel

Bases: FHIRBaseModel

Base class for representation of FHIR profiled slices as Pydantic objects.

Expands the FHIRBaseModel class with slice-specific methods.

Attributes:

Name	Type	Description
is_FHIR_complete		Validates if the FHIR model is complete by attempting to validate the model dump.
has_been_modified		Checks if the FHIRSliceModel instance has been modified by comparing it with a new instance constructed with slices.

is_FHIR_complete property

is_FHIR_complete

Validates if the FHIR model is complete by attempting to validate the model dump. Returns True if the model is complete, False otherwise.

has_been_modified property

has_been_modified

Checks if the FHIRSliceModel instance has been modified by comparing it with a new instance constructed with slices. Returns True if the instance has been modified, False otherwise.
