- **题库管理 / 练习记录 / 错题本 / 章节测试采用「清单 + 试卷」分屏工作台**
|
||||||
|
（`components/SplitView.tsx` + `Pane`）：一栏是可搜索的清单，另一栏按真实试卷版式
|

|
排题目；两栏各自独立滚动，清单不会把试卷顶走，整页不再是一条长滚动条。
|

侧栏首行显示题库总数，并提示还有多少题没挂到章节（计数来自 `/api/question-bank/summary`）。

|
||||||

我的作答 / 正确答案 / 解析，底部上一题、下一题翻页。

并用它拉一个 CPython 3.12），或 `brew install python@3.12`。

《函数和图像》的章节（引言、第1章 例子 … 第7章 有理函数）已写入数据库，
|
**有正式目录的书，章节由种子预置**：`seed/catalog.py` 里 `OFFICIAL_*_CHAPTERS`
|
||||||
可据此按章节生成新题；其余分册目录可在 `backend/seed/catalog.py` 中扩充后重启生效
|
是核对过原书的正式目录，按 ISBN 绑到 `CATALOG[*].chapters`，`python -m seed`
|
||||||
（幂等同步，不清空学习记录）。
|
与后端启动都会幂等地补齐章节，并按 `KNOWLEDGE_CHAPTER_MAP` /
|
||||||
|
`DEFAULT_CHAPTER_KNOWLEDGE` 把演示题与知识点挂上去（只补空，不覆盖人工改动）。
|
||||||
|
目前已落地：函数和图像 8 章、三角函数 10 章、坐标方法 7 章、几何 4 章。
|
||||||
|
|
||||||
|
**没有正式目录的书不由种子编造**（代数、普林斯顿微积分读本、柯西-施瓦茨大师课）。
|
||||||
|
管理员在「教材 / 课程」打开某本教材的章节面板后，有三种方式：
|
||||||
|
|
||||||
|
1. 「添加章节」手动逐条录入名称与内容提示；
|
||||||
|
2. 「AI 整理章节」：把书的目录原文（版权页/目录页文字，或在别处查到的正式目录）粘进
|
||||||
|
「目录参考数据」，任务在后台解析目录并为每章挂上知识图谱节点；模型只做整理，
|
||||||
|
不新增、不补造素材里没有的章节；
|
||||||
|
3. 纯接口方式 `POST /api/textbooks/{id}/chapters/generate`：先按 ISBN 查 Open Library /
|
||||||
|
Google Books 的正式目录，再让模型按正式目录还原，查不到且模型没把握时直接拒绝写入。
|
||||||
|
|
||||||
|
确认无误的正式目录也可以回填到 `backend/seed/catalog.py` 的
|
||||||
|
`OFFICIAL_*_CHAPTERS` / `CATALOG[*].chapters`，再执行
|
||||||
|
`cd backend && .venv/bin/python -m seed`（幂等：只补缺，不覆盖界面上的修改，也不清空学习记录），
|
||||||
|
这样换机器或库丢了都能一并重建。
|
||||||
|
|
||||||
|
> 种子题库的 18 道演示题会按知识点自动挂到《函数和图像》的章节下（当前：引言 3 题、
|
||||||
|
> 第6章 幂函数 15 题），所以「章节测试」开箱就能组卷；管理员手工改过的章节归属不会被覆盖。

`--force` 执行前会自动把当前库备份到 `data/backups/`（打印路径），误操作可用
|
||||||
|
`./scripts/db.sh restore` 回退。
|
||||||
|
|
||||||
|
## 数据备份与恢复
|
||||||
|
|
||||||
|
`data/*.db` 在 `.gitignore` 里，仓库只有代码和电子书，**数据库文件从来没有进过远端**：
|
||||||
|
库一旦被重置，章节、题目这些内容就跟着没了。为此有两层保险：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./scripts/db.sh path # 数据库文件位置
|
||||||
|
./scripts/db.sh backup 升级前 # 时间戳备份（用 SQLite backup API，服务在写也安全）
|
||||||
|
./scripts/db.sh list # 本机备份列表（默认保留最近 20 份）
|
||||||
|
./scripts/db.sh restore [文件|latest] # 回滚；覆盖前先把当前库再备份一份
|
||||||
|
./scripts/db.sh dump # 导出 data/dump/catalog.sql（内容快照，建议随改动提交）
|
||||||
|
./scripts/db.sh load # 把 data/dump/catalog.sql 灌回当前库
|
||||||
|
```
|
||||||
|
|
||||||
|
* `dump` 只导**内容**：教材、章节、知识点与关联、课程、题库。
|
||||||
|
这份文本提交进 git，远端仓库里就始终有一份可恢复的数据库快照。
|
||||||
|
* 账号、密码散列、答题记录、错题本属于个人数据，**不进 dump、不进 git**；
|
||||||
|
需要整机迁移时用 `./scripts/db.sh dump --full`（写到 `data/backups/math.full.sql`）
|
||||||
|
或直接用 `backup` 的二进制备份。
|
||||||
|
* 新机器上的恢复顺序：`./scripts/init.sh`（建库 + 种子）→ `./scripts/db.sh load` → 重启后端。
|
||||||
|
* 电子书与库分离：`data/ebooks/` 随仓库提交，库只存文件名。
|
||||||
|
若库丢了，`seed/ebooks.py` 会按「大小 + SHA-256」认领磁盘上的已知电子书
|
||||||
|
（`KNOWN_EBOOKS`），重建教材条目并把文件挪回该书目录，不必重新上传。
