feat(阶段4): 用户管理 + 成就管理;补上 rescan 与 contest_joined
GET/POST/DELETE admin/users (DELETE 走 body 传 ids) GET/PUT admin/users/:id POST admin/users/:id/reset-password GET admin/achievement-metrics GET/POST admin/achievements GET/PUT/DELETE admin/achievements/:id 顺带补了新后端缺失的两块(不补的话成就后台建出来的东西是坏的): 1. **rescanAchievement**:旧后端 `rescan_achievement` 的对应实现。判定平时只在判题 结算时发生,后台新建成就或调低阈值不会自动补发,必须显式扫一遍。补发标记 backfilled=true —— 前端据此只显示「已获得」不显示日期,否则一次补发会给几百人 盖同一个时间戳,把「最近获得」板块冲垮。 触发判据包含 metric 与 visible 的变化,不只看 operator/threshold:换维度、 以及从下架改上架(草稿期已达标的人)这两种都会漏。 2. **contest_joined 指标整个漏掉了**。旧 METRIC_REGISTRY 有 18 个指标,新后端只算 17 个,配在这个指标上的成就永远解锁不了。已补上计算,并把注册表抽成 services/achievement-metrics.ts 作为单一事实源 —— 后台下拉框和参数校验都读它, 避免「下拉框里选得到但没人算」这种组合。 用户管理的几处要点: - className 解析位数不对**直接报错不猜**。猜错会把 class_name 存歪,而剥前缀显示 姓名、班级下拉、统计页都依赖它准确。 - problem_permission 按 admin_type 归一(超管恒 All、普通用户恒 None),否则把超管 降级成普通用户后他还留着 All。 - 改用户名要同步 submission.username 这个冗余列,否则历史提交查不到。 - openApi 已开着就不重置 appkey,否则每次保存用户都把对方的 key 换掉。 - **删除用户不复刻 Django 的应用层级联硬删**。用户是被引用最广的一张表,改成让 数据库外键拦下来:撞外键说明还有历史数据,应当禁用而不是删除,返回 409 并说明。 实测:学生 403;导入 2 人 / 重复 409 / 班级号位数报错文案正确;改名+降权后 permission 归一为 None、重名 409;重置密码 6 位无 0;删自己 400; 成就指标 18 项、新建后补发 unlockCount=2、野指标与野稀有度均 400。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
