|
|
-- 重新設計評分數據庫架構
|
|
-- 讓評分系統完全基於 competition_rules 的動態內容
|
|
-- =====================================================
|
|
|
|
-- 1. 創建新的評分記錄表（基於競賽規則）
|
|
CREATE TABLE `judge_scores` (
|
|
`id` VARCHAR(36) PRIMARY KEY,
|
|
`judge_id` VARCHAR(36) NOT NULL,

|

|
|

|
|

|
|
`comments` TEXT,
|
|
`submitted_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
|
|
|
|
FOREIGN KEY (`judge_id`) REFERENCES `judges`(`id`) ON DELETE CASCADE,
|
|
FOREIGN KEY (`app_id`) REFERENCES `apps`(`id`) ON DELETE CASCADE,
|
|
FOREIGN KEY (`competition_id`) REFERENCES `competitions`(`id`) ON DELETE CASCADE,
|
|
UNIQUE KEY `unique_judge_app_competition` (`judge_id`, `app_id`, `competition_id`),

|
INDEX `idx_competition` (`competition_id`),
|
|
INDEX `idx_total_score` (`total_score`)
|
|
);

|
|
