From 8f67883be164a4f6810f1b2c642c320d725dbf6b Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Thu, 23 Oct 2025 08:35:24 -0500 Subject: [PATCH] CLAUDE: Implement polymorphic Lineup model for PD and SBA leagues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Updated Lineup model to support both leagues using the same pattern as RosterLink: - Made card_id nullable (PD league) - Added player_id nullable (SBA league) - Added XOR CHECK constraint to ensure exactly one ID is populated - Created league-specific methods: add_pd_lineup_card() and add_sba_lineup_player() - Replaced generic create_lineup_entry() with league-specific methods Database migration applied to convert existing schema. Bonus fix: Resolved Pendulum DateTime + asyncpg timezone compatibility issue by using .naive() on all DateTime defaults in Game, Play, and GameSession models. Updated tests to use league-specific lineup methods. Archived migration docs and script to .claude/archive/ for reference. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../archive/LINEUP_POLYMORPHIC_MIGRATION.md | 186 ++++++++++++++++++ .claude/archive/migrate_lineup_schema.py | 64 ++++++ backend/CLAUDE.md | 19 +- backend/app/database/operations.py | 59 +++++- backend/app/models/db_models.py | 29 ++- .../integration/database/test_operations.py | 37 ++-- .../integration/test_state_persistence.py | 12 +- 7 files changed, 373 insertions(+), 33 deletions(-) create mode 100644 .claude/archive/LINEUP_POLYMORPHIC_MIGRATION.md create mode 100644 .claude/archive/migrate_lineup_schema.py diff --git a/.claude/archive/LINEUP_POLYMORPHIC_MIGRATION.md b/.claude/archive/LINEUP_POLYMORPHIC_MIGRATION.md new file mode 100644 index 0000000..78e7c05 --- /dev/null +++ b/.claude/archive/LINEUP_POLYMORPHIC_MIGRATION.md @@ -0,0 +1,186 @@ +# Lineup Model - Polymorphic Migration Summary + +**Date**: 2025-10-23 +**Status**: ✅ COMPLETE + +## Overview + +Updated the `Lineup` database model to support both PD and SBA leagues using a polymorphic design pattern, matching the approach used in `RosterLink`. + +## Changes Made + +### 1.
