Summary

Enforces parent-child integrity for NMA legacy tables and refactors them from UUID to Integer primary keys for consistency with the rest of the schema.

Fixes #363

Changes

1. Integer PK Refactoring

  • Added id (Integer, autoincrement) as primary key to 8 NMA tables
  • Renamed existing UUID columns with nma_ prefix for audit/traceability
  • Standardized FK naming to chemistry_sample_info_id (Integer) pattern

2. Tables Modified

Table New PK Legacy UUID Column
NMA_Chemistry_SampleInfo id nma_sample_pt_id
NMA_FieldParameters id nma_global_id
NMA_MajorChemistry id nma_global_id
NMA_MinorTraceChemistry id nma_global_id
NMA_Radionuclides id nma_global_id
NMA_HydraulicsData id nma_global_id
NMA_Stratigraphy id nma_global_id
NMA_AssociatedData id nma_assoc_id

3. FK Enforcement

Model Parent FK Rationale
NMA_Chemistry_SampleInfo location_id → Location 99.95% match rate vs ~67% with Thing
NMA_HydraulicsData thing_id → Thing Well-specific data
NMA_Stratigraphy thing_id → Thing Well-specific data
NMA_Radionuclides thing_id → Thing Well-specific data
NMA_AssociatedData thing_id → Thing Well-specific data
NMA_Soil_Rock_Results thing_id → Thing Well-specific data

Chemistry → Location rationale:

  • LocationId in legacy data maps to Location.nma_pk_location with 99.95% match rate
  • Only ~2 truly orphan records (vs ~71k with Thing matching)
  • Avoids creating stub Things just for FK satisfaction
  • Simpler implementation - no new transfer phases needed

4. Code Updates

  • Models (db/nma_legacy.py): Updated column definitions and relationships
  • Models (db/location.py): Added chemistry_sample_infos relationship
  • Transfers (transfers/*.py): Updated column mappings for new schema
  • Admin views (admin/views/*.py): Updated pk_attr and pk_type
  • Tests: Renamed to nma-legacy-relationships pattern, updated for Location FK

Orphan Records Discovered

The FK enforcement successfully prevented orphan records from being transferred:

Table Valid Records Orphan Records Prevented
HydraulicsData 0 288
ChemistrySampleInfo ~71,600 ~2 (Location-based)
MajorChemistry 16,532 62,046
Radionuclides 12 351
MinorTraceChemistry 31,721 76,640
FieldParameters 2,899 11,035

Test Plan

  • All 435 tests passing (1 skip due to GCS connectivity)
  • Transfer scripts run successfully against dev database
  • Cascade deletes verified in integration tests
  • Orphan records correctly filtered during transfer
  • Chemistry → Location FK tested in test_nma_chemistry_lineage.py

Pull request overview

This PR adds a comprehensive feature specification that defines business requirements for well data relationships in the NMBGMR system, ensuring parent-child integrity between wells and their associated data records.

Changes:

  • Defines requirements for wells to store legacy identifiers (WellID and LocationID) from NM_Aquifer
  • Specifies that all well-related records (chemistry, hydraulics, stratigraphy, radionuclides, associated data, soil/rock) must have a parent well
  • Establishes cascade delete behavior to prevent orphaned records when wells are deleted

test: add failing tests for Thing FK enforcement (Issue #363)
e355b30 
Add integration and unit tests for well data relationships feature:

- Integration tests (test_well_data_relationships.py):
  - Wells store legacy identifiers (nma_pk_welldata, nma_pk_location)
  - Related records require a well (thing_id cannot be None)
  - Relationship navigation from Thing to NMA legacy models
  - Cascade delete behavior

- Unit tests added to existing files:
  - test_thing.py: Thing column and relationship assertions
  - test_hydraulics_data_legacy.py: validator and back_populates
  - test_associated_data_legacy.py: validator and back_populates
  - test_soil_rock_results_legacy.py: validator and back_populates
  - test_radionuclides_legacy.py: FK cascade and back_populates
  - test_stratigraphy_legacy.py (new): validator and back_populates

These tests are expected to fail until the model changes are implemented.

SQLAlchemy-continuum creates a thing_version table that mirrors
the thing table structure. The migration must add the new column

fix(tests): restore test database configuration
464a6cf 
Restore POSTGRES_DB and POSTGRES_PORT settings that were accidentally
removed in commit 62ecda1 during the NMA_ prefix refactoring.

Without these settings, tests would connect to ocotilloapi_dev instead
of ocotilloapi_test because load_dotenv(override=True) would overwrite
the POSTGRES_DB set by pytest_configure().

refactor(models): migrate NMA tables to Integer PKs with nma_ prefix
f24ad39 
Update all NMA legacy models to use Integer autoincrement primary keys
instead of UUID PKs. Legacy columns are renamed with nma_ prefix for
audit/traceability.

Changes per table:
- NMA_HydraulicsData: id (Integer PK), nma_global_id, nma_well_id, nma_point_id, nma_object_id
- NMA_Stratigraphy: id (Integer PK), nma_global_id, nma_well_id, nma_point_id, nma_object_id
- NMA_Chemistry_SampleInfo: id (Integer PK), nma_sample_pt_id, nma_sample_point_id, nma_wclab_id, nma_location_id, nma_object_id
- NMA_AssociatedData: id (Integer PK), nma_assoc_id, nma_location_id, nma_point_id, nma_object_id
- NMA_Radionuclides: id (Integer PK), nma_global_id, chemistry_sample_info_id (Integer FK), nma_sample_pt_id, nma_sample_point_id, nma_object_id, nma_wclab_id
- NMA_MinorTraceChemistry: id (Integer PK), nma_global_id, chemistry_sample_info_id (Integer FK), nma_chemistry_sample_info_uuid
- NMA_MajorChemistry: id (Integer PK), nma_global_id, chemistry_sample_info_id (Integer FK), nma_sample_pt_id, nma_sample_point_id, nma_object_id, nma_wclab_id
- NMA_FieldParameters: id (Integer PK), nma_global_id, chemistry_sample_info_id (Integer FK), nma_sample_pt_id, nma_sample_point_id, nma_object_id, nma_wclab_id
- NMA_Soil_Rock_Results: nma_point_id (rename only, already had Integer PK)

Chemistry chain children now use Integer FK (chemistry_sample_info_id)
pointing to NMA_Chemistry_SampleInfo.id instead of UUID FK.

feat(transfers): Wire up non-well location transfers in main pipeline
9223761 
Add springs, perennial streams, ephemeral streams, and met stations
to the automated transfer pipeline. These run in PHASE 1.5 (after wells,
before chemistry transfers) to ensure all location types have Things
created before dependent transfers run.

- Add transfer_springs, transfer_perennial_stream, transfer_ephemeral_stream,
  transfer_met from thing_transfer.py
- Add TransferOptions fields and env vars (TRANSFER_SPRINGS, etc.)
- Run non-well transfers in parallel for efficiency
