# Legacy Attendance — Deployment Package
Adds a read-only "Legacy Attendance" sidebar item: dashboard + records list +
Excel export, sourced LIVE from the OLD remote MySQL server
(`contract` / `employee` / `locations` / `records` tables). No import, no
writes to the remote DB, nothing copied into the local database.
Apply this same package to **both LT and GOV** (each server uses its own
`REMOTE_DB_*` values in its own `.env`).
---
## 1. Files in this package
### NEW files (just drop in — no existing file touched)
| File | Purpose |
|------|---------|
| `legacy_attendance_service.py` | Read-only pymysql data access to the legacy DB (queries, pagination, Excel builder) |
| `routes/legacy_attendance.py` | Blueprint `legacy_attendance` — dashboard, records, export routes |
| `templates/legacy_attendance_dashboard.html` | Dashboard page |
| `templates/legacy_attendance_records.html` | Records list (matches the Time Attendance table layout) |
| `tools/migration_legacy_attendance_remote_indexes.py` | One-time index migration for the REMOTE legacy DB |
### MODIFIED files (replace existing)
| File | What changed |
|------|--------------|
| `config.py` | Added `REMOTE_DB_HOST/PORT/USERNAME/PASSWORD/NAME` to `Config` |
| `app.py` | Registered the `legacy_attendance` blueprint |
| `templates/base_authenticated.html` | Added "Legacy Attendance" sidebar link (admin + payroll/accounting sections) |
Nothing was removed or renamed. Existing routes/functions/variables untouched.
---
## 2. .env additions (BOTH servers)
Add these to `.env` on each server, using that server's own legacy DB
credentials:
```
# Remote MySQL Server Configuration (Source — legacy attendance)
REMOTE_DB_HOST=xxx.xxx.xxx.xxx
REMOTE_DB_PORT=3306
REMOTE_DB_USERNAME=xxx
REMOTE_DB_PASSWORD=xxx
REMOTE_DB_NAME=xxx
```
If these are left blank, the Legacy Attendance pages show a clean
"legacy database is not configured" flash message instead of erroring.
---
## 3. One-time index migration (BOTH servers)
The legacy schema ships with no useful indexes, which makes the live queries
full-scan and can trip the gunicorn worker timeout at scale. Run once per
server (safe to re-run — skips indexes that already exist; only adds indexes,
never touches data):
```
python3 tools/migration_legacy_attendance_remote_indexes.py
```
Expected first-run output: `[ADD]` lines for 6 indexes on
`records` / `employee` / `locations`, then `[DONE]`.
> Note: on a fresh legacy DB dump these indexes may already be present
> (a recent dump already includes them). In that case every line prints
> `[SKIP]` — that's fine.
---
## 4. Deploy steps (per server)
1. Copy the NEW files into place.
2. Replace the 3 MODIFIED files.
3. Add the `REMOTE_DB_*` block to `.env`.
4. `python3 tools/migration_legacy_attendance_remote_indexes.py`
5. Restart gunicorn.
6. Log in, open **Legacy Attendance** in the sidebar, confirm the dashboard
stats populate and the records list shows Location Name + Event Description.
No local DB migration is required — this feature reads the remote DB only.
---
## 5. Key facts worth remembering
- `records.locationId` holds the numeric **`locations.index`** (NOT the
location name). The join is
`locations.index = CAST(records.locationId AS UNSIGNED)`.
- `records.employeeId` is varchar; joined as
`employee.id = CAST(records.employeeId AS UNSIGNED)`.
- `records.type` values are `CHECK IN` / `CHECK OUT`.
- Records list column mapping:
ID=`employeeId`, Name=`Last, First`, Platform=`Manual`/`—` (from `isManual`),
Date/Time from `time`, Location Name=`locations.location`,
Action Description=`type` badge, Event Description=`locations.address`,
Recorded Address=`records.recordedAddress`.
- Read-only by design: no detail page, no delete (so no Actions column).

"""
legacy_attendance_service.py
=============================
Read-only data access for the "Legacy Attendance" feature.
This talks directly to the OLD remote MySQL server (the one described by
QrCodeLtServices.sql: `contract`, `employee`, `locations`, `records` tables)
using pymysql — never SQLAlchemy ORM — because that schema is completely
different from the current app's models and is not, and should never be,
mapped as a SQLAlchemy model.
Connection is opened per-call and closed immediately after use (no pooling,
no persistent connection kept on `g` or the app) because this data is only
ever displayed, never written to. Nothing here performs INSERT/UPDATE/DELETE
against the remote server.
Env vars (already used by employee_table_sync.py):
REMOTE_DB_HOST
REMOTE_DB_PORT
REMOTE_DB_USERNAME
REMOTE_DB_PASSWORD
REMOTE_DB_NAME

"""
migration_legacy_attendance_remote_indexes.py
================================================
Adds missing indexes to the REMOTE legacy database (the one described by
QrCodeLtServices.sql — contract / employee / locations / records) so the
Legacy Attendance feature's live queries don't full-table-scan on every
page load.
As shipped, that schema has NO index on:
records.employeeId, records.locationId, records.time, records.contractId
employee.id (only the meaningless auto-increment `index` is indexed)
locations.location
Adding an index does not change or risk any existing data — it only
speeds up reads. Safe to re-run: each ALTER is skipped if the index
already exists.
Uses pymysql directly (never SQLAlchemy ORM), consistent with every other
migration script in tools/ — this connects to REMOTE_DB_* (the legacy
server), not the app's own local database.
Run once per server (LT and GOV each point at their own legacy DB):
