Patient records can be created without a pincode or blood group; omitted values remain empty.
Partial updates preserve existing blood group and deceased date and time when those fields are omitted. An omitted or empty pincode is set to empty.
Omitted patient details no longer unintentionally change existing values, while explicitly supplied values—including an age of zero—are handled correctly.
Patient updates and creation continue to reject invalid birth-date and death-date combinations.
Navigate logical layers of code changes, visualize relationships, and explore their blast radius.
📝 Walkthrough
Walkthrough
Patient field specifications and API validation now distinguish omitted fields from explicitly supplied values. Deserialization applies age, date-of-birth, geo-organization, and pincode changes based on supplied values. API tests cover age zero, date validation, omitted creation fields, and preservation of existing values during partial updates.

Summary
Patient field deserialization care/emr/resources/patient/spec.py
Create and update specifications use MISSING to distinguish omitted fields from supplied values. Deserialization applies age zero and handles date of birth, geo-organization, and pincode based on supplied values.
Patient validation and API tests care/emr/api/viewsets/patient.py, care/emr/tests/test_patient_api.py
Validation falls back to stored values only when fields are MISSING and checks age zero against death year. Tests cover date validation, omitted creation fields, partial updates, and cached identifier configuration setup.
Unrelated patient updates can erase a stored pincode, so the update path should be fixed before merge. A smaller open concern is that an age-only update may be validated against the previous date of birth.
Security Architecture Review
Security architecture risk:🟡 Moderate · up to ecb2a
Patient writes now distinguish omitted fields from explicit values. This improves validation of age zero, but it also makes an explicit null capable of clearing a recorded death date. The intended permission and client behavior for that transition need confirmation.
Retained concerns
Medium · security · inferred: An explicit null on an authorized patient update can now clear a recorded death date and cause validation to evaluate that write without the previously stored death date. Whether ordinary patient-write permission is intended to authorize this sensitive state transition is unresolved.
Security review details
Security Blast Radius
inferred — The identified transition is reachable through writes to patients the caller is permitted to update. The available evidence does not establish the full set of writable patients or downstream consumers of death status.
Security Findings and Attack Paths
inferred — A caller with patient-write permission can submit deceased_datetime as null. Unlike the previous null-as-default behavior, that value can be persisted as a clear and makes the death-date comparisons in that write inapplicable. No unauthorized caller or downstream exploit was established.
Trust Boundaries and Controls
observed — Patient-write authorization is checked at the viewset boundary, and supplied age zero is checked against an effective death date when one remains present.
Hardening Proposals
proposed — Confirm whether clearing a recorded death date requires a distinct policy or explicit client action, and cover null-bearing partial updates against that intended contract.

Validate the effective date of birth when an update supplies age.
EMRUpdateMixin.handle_update calls validate_data before deserialization. When date_of_birth is omitted, the current check uses the persisted DOB. PatientUpdateSpec.perform_extra_deserialization then clears that DOB and derives year_of_birth from age.
For a persisted record with a data-entry error—DOB 2000-01-01 and death date 1999-01-01—a PATCH with age=30 in 2026 is rejected by the stale DOB check. The effective update would instead have date_of_birth=None and year_of_birth=1996, which passes the age/year check. This is limited to records that are already inconsistent, but it blocks correcting them through an age update.
Use the effective DOB for updates that supply age.

Preserve pincode when an update omits it.
If a PATCH omits pincode, PatientUpdateSpec.pincode is MISSING. This condition then sets obj.pincode to None, so an unrelated update erases the stored pincode. Keep the create-time default, but clear pincode during an update only when the request explicitly supplies a falsy value. The new omission sentinel should not count as a request to clear the field.
Proposed change
- if self.pincode is MISSING or not self.pincode:+ if (not is_update and self.pincode is MISSING) or (+ self.pincode is not MISSING and not self.pincode+ ):
obj.pincode = None

PatientListSpec and PatientRetrieveSpec inherit this annotation, but omitted pincodes are deliberately persisted and returned as None (the new test asserts that at test_patient_api.py:906). Removing None therefore makes the generated response schema reject a value the endpoint emits. Keep None in the union so the read contract remains accurate while MISSING can still distinguish omission in request models.
