Problem

GET /api/v2/cards/{card_id}?csv=true raised AttributeError at runtime because v1_cards_get_one referenced this_card.roster1.name, this_card.roster2.name, this_card.roster3.name — fields that do not exist on the Card model.

Root Cause

Dead code referencing removed/never-implemented roster relationship fields on the Card ORM model. The Card model only has player, team, pack, value.

Solution

Removed roster1, roster2, roster3 from both the CSV header row and data row in v1_cards_get_one (app/routers_v2/cards.py).

Files Changed

• app/routers_v2/cards.py — removed roster columns from CSV output

Notes

• ruff linter hook reformats entire file on save (single→double quotes, line wrapping) — cosmetic noise in the diff
• v1_cards_patch still accepts roster1_id, roster2_id, roster3_id query params that are silently ignored — tracked as separate cleanup
