WJ import loader: catalog + assets-hub stages (the machineid->assetid crosswalk)
Adds the keystone stages to the reference loader.

catalog: seeds modeltypes (from classic machinetypes + category), the per-plugin
asset subtypes routed by machinetype (machines/network/measuringtool types),
computer subtypes (from pctype), the 5-row controllertypes vendor/model split,
and the models catalog - each with a persisted legacy->new crosswalk. Verified:
modeltypes 31, computertypes 12, models 118.

assets (the hub): fans classic machines out to the right endpoint by
machinetypeid (+ the pctype metrology override), applying the resolved
decisions - assetnumber = machinenumber else hostname, skip 9999, skip duplicate
machinenumbers, LocationOnly/printer/USB routed out. Persists the machineid ->
assetid crosswalk every downstream stage needs. Verified against a fresh scratch
target: 884 assets (computer 623, machine 68, network 58, measuringtool 135),
zero endpoint errors, idempotent re-run (stays 884). Skips: location 158, dup 69,
other 53, 9999 1.

Harness now runs each plugin's idempotent on_install so the AssetType rows exist
(a DB built with plugin upgrade-all instead of a fresh install lacks them, and
the create routes 500 without them). 409-resolve lookups page through per_page.

Remaining stages: communications (primary IP fold - source is the communications
table, not machines.ipaddress1), applications/installs, warranties, notifications,
KB, subnets/VLANs, usb, verify.

WJ classic-ASP import loader (reference implementation)

This is site-specific reference glue, not product code. It maps West Jefferson's classic-ASP shopdb / cmmc_usb / wjf_employees schema onto the maintained, schema-agnostic import contract in docs/IMPORT-API.md.

Every adopting site has its own source database. Nobody else runs this loader. Instead, copy the pattern:

  1. Point the harness at your source DB(s) (edit harness.Source).
  2. Write per-entity stages that read your tables and POST to the same docs/IMPORT-API.md endpoints with Authorization: Bearer <admin PAT> and X-Import-Mode: true.
  3. Persist legacy-id -> new-id crosswalks (see harness.IdMap) so later stages resolve foreign keys and a crashed run resumes.

The import API is the stable contract; loaders are per-site. The mapping itself can be produced with the agent-assisted workflow (point Fable/Opus agents at a source DB + this contract -> they emit the mapping + a loader skeleton).

Running (against a THROWAWAY import database)

DATABASE_URL='mysql+pymysql://root:PW@127.0.0.1:3306/shopdb_flask_import?charset=utf8mb4' \
  venv/bin/python -m scripts.site_imports.wjf.run --stages reference,employees

Prereqs: a fresh target DB built with flask db upgrade + flask plugin upgrade-all + flask seed permissions/settings/reference-data, and the three source dumps loaded into scratch DBs (shopdb_src, cmmc_usb_src, wjf_employees_src). See scratchpad/IMPORT-PLAN.md for the full mapping, resolved decisions, and remaining stages.

Status

  • Implemented + verified idempotent: reference (vendors, businessunits, operatingsystems), employees (directory bulk upsert; photos deferred).
  • TODO stages: models, applications, assets (the hub - fan machines out by type, persist the machineid->assetid crosswalk), dependents (installs, warranties, notifications, KB), network (+ subnets/VLANs), usb (cmmc device + checkinout pairing), verify.

The harness (PAT auth, import-mode, id-map persistence, endpoint error capture) is proven; the remaining stages are additional stage_* functions in run.py following the same shape.
