Completed Phase 1 of Paper Dynasty SQLite to PostgreSQL migration:
|
|
|
|
FILES CREATED:
|
|
- scripts/migrate_to_postgres.py - ID-preserving migration script with batch processing, FK error handling
|
|
- scripts/audit_sqlite.py - Pre-migration data integrity checker
|
|
- app/db_helpers.py - Cross-database upsert helpers for SQLite/PostgreSQL compatibility
|
|
- PROJECT_PLAN.json - Comprehensive migration tracking
|
|
- .secrets/pd_admin_credentials.txt - PostgreSQL credentials (gitignored)
|
|
|
|
CODE CHANGES:
|
|
- app/db_engine.py: Added unique indexes for StratPlay(game, play_num) and Decision(game, pitcher)
|
|
- app/db_engine.py: Added max_length to Team.abbrev, sname, lname fields
|
|
- 12 files updated: Replaced on_conflict_replace() with PostgreSQL-compatible upsert_*() helpers
|
|
- teams.py: Fixed boolean comparison (== 0/1 to == False/True)
|
|
|
|
AUDIT RESULTS:
|
|
- 658,963 total records across 29 tables
|
|
- 2,390 orphaned stats records (will be handled by migration script)
|
|
- No critical issues blocking migration
|
|
|
|
NEXT STEPS:
|
|
- Create pd_admin user and pd_master database on sba_postgres
|
|
- Test migration on dev server (ssh sba-db)
|
|
- Production migration with 1-4 hour maintenance window
