## 🔴 Public Schema历史遗留问题(与ASL无关)
|
||||
|
||||
### 问题描述
|
||||
|
||||
在项目早期开发中,部分模块的表被错误地创建在 `public` schema 中,违反了Schema隔离策略:
|
||||
|
||||
| 错误表名 | 应在Schema | 当前状态 |
|
||||
|---------|-----------|---------|
|
||||
| `public.users` | `platform_schema` | ⚠️ 重复存在 |
|
||||
| `public.projects` | `aia_schema` | ⚠️ 重复存在 |
|
||||
| `public.conversations` | `aia_schema` | ⚠️ 重复存在 |
|
||||
| `public.messages` | `aia_schema` | ⚠️ 重复存在 |
|
||||
| `public.knowledge_bases` | `pkb_schema` | ⚠️ 重复存在 |
|
||||
| `public.documents` | `pkb_schema` | ⚠️ 重复存在 |
|
||||
| `public.batch_tasks` | `pkb_schema` | ⚠️ 重复存在 |
|
||||
| `public.batch_results` | `pkb_schema` | ⚠️ 重复存在 |
|
||||
|
||||
**数据对比(2025-11-23快照)**:
|
||||
|
||||
```
|
||||
platform_schema.users: 3条记录
|
||||
public.users: 2条记录
|
||||
|
||||
aia_schema.projects: 2条记录
|
||||
public.projects: 2条记录
|
||||
|
||||
pkb_schema.knowledge_bases: 2条记录
|
||||
public.knowledge_bases: 2条记录
|
||||
```
|
||||
|
||||
**影响范围**:
|
||||
- 🟢 **不影响ASL模块**(ASL完全隔离在asl_schema)
|
||||
- ⚠️ 影响AIA模块(AI助手)
|
||||
- ⚠️ 影响PKB模块(知识库)
|
||||
- ⚠️ 影响Platform模块(用户系统)
|
||||
|
||||
**责任归属**:
|
||||
- 🔵 ASL团队:无责任,数据管理完全正确
|
||||
- 🟡 其他模块团队:需自行清理public schema数据

## 🛠️ 2025-11-23迁移操作记录
|
||||
|
||||
### 迁移目标
|
||||
|
||||
为全文复筛功能(Day 4开发)添加数据库支持:
|
||||
1. 修改 `literatures` 表(添加全文相关字段)
|
||||
2. 创建 `fulltext_screening_tasks` 表
|
||||
3. 创建 `fulltext_screening_results` 表
|
||||
|
||||
### 迁移策略选择
|
||||
|
||||
**❌ 方案A:Prisma Migrate(被拒绝)**
|
||||
|
||||
```bash
|
||||
npx prisma migrate dev --name add_fulltext_screening
|
||||
```
|
||||
|
||||
**拒绝原因**:
|
||||
- Prisma会尝试删除 `public` schema中的重复表
|
||||
- 可能影响其他模块的数据
|
||||
- 违反"管好自己"的原则
|
||||
|
||||
**✅ 方案B:手动SQL脚本(已采用)**
|
||||
|
||||
```bash
|
||||
# 创建手动迁移脚本
|
||||
backend/prisma/migrations/manual_fulltext_screening.sql
|
||||
|
||||
# 执行迁移(仅操作asl_schema)
|
||||
Get-Content manual_fulltext_screening.sql | docker exec -i ai-clinical-postgres psql ...
|
||||
```
|
||||
|
||||
**优势**:
|
||||
- ✅ 只操作 `asl_schema`,不动其他schema
|
||||
- ✅ 不删除任何 `public` 数据
|
||||
- ✅ 安全、可控、可审计
|
||||
- ✅ 符合"管好自己"原则
|
||||
|
||||
### 迁移内容详情
|
||||
|
||||
#### 1. 修改 `literatures` 表
|
||||
|
||||
新增字段(13个):
|
||||

|
||||
|
||||
**唯一约束**:
|
||||
- `unique_project_literature_fulltext (project_id, literature_id)`
|
||||
|
||||
**外键约束**:
|
||||
- `task_id` → `fulltext_screening_tasks(id)` ON DELETE CASCADE
|
||||
- `project_id` → `screening_projects(id)` ON DELETE CASCADE
|
||||
- `literature_id` → `literatures(id)` ON DELETE CASCADE
|
||||
|
||||
### 迁移结果验证
|
||||
|
||||
```sql
|
||||
-- 验证表创建
|

**Prisma Client生成**:
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
npx prisma generate
|
||||
|
||||
# 结果:✅ 生成成功
|
||||
# 代码可访问:
|
||||
# - prisma.aslLiterature
|

## 📐 Schema隔离策略执行情况
|
||||
|
||||
### 设计原则(来自系统架构文档)
|
||||
|
||||
```
|
||||
各模块数据逻辑隔离:
|
||||
├── admin_schema (系统管理)
|
||||
├── platform_schema (用户系统)
|
||||
├── aia_schema (AI助手)
|
||||
├── asl_schema (AI智能文献) ✅ 执行正确
|
||||
├── pkb_schema (知识库)
|
||||
├── rvw_schema (审阅协作)
|
||||
├── st_schema (统计分析)
|
||||
├── dc_schema (数据采集)
|
||||
├── ssa_schema (样本量分析)
|
||||
└── common_schema (公共数据)
|
||||
```
|
||||
|
||||
### ASL模块执行情况 ✅
|
||||
|
||||
| 检查项 | 状态 | 说明 |
|
||||
|-------|------|------|
|
||||
| Schema命名 | ✅ 正确 | `asl_schema` |
|
||||
| 所有表都在正确Schema | ✅ 正确 | 6个表全部在 `asl_schema` |
|
||||
| 没有表在public | ✅ 正确 | 无泄漏 |
|
||||
| Prisma Model映射正确 | ✅ 正确 | `@@schema("asl_schema")` |
|
||||
| 代码访问路径正确 | ✅ 正确 | `prisma.aslXxx` |
|
||||
| 外键约束内部化 | ✅ 正确 | 所有FK指向同schema表 |
|
||||
|
||||
**代码示例**(正确访问方式):
|
||||
|
||||
```typescript
|
||||
// ✅ 正确:通过Prisma Client访问asl_schema
|
||||
const project = await prisma.aslScreeningProject.findUnique({
|
||||
where: { id: projectId },
|
||||
});
|
||||
|
||||
const literatures = await prisma.aslLiterature.findMany({
|
||||
where: { projectId },
|
||||
});
|
||||
|
||||
const task = await prisma.aslFulltextScreeningTask.create({
|
||||
data: { ... },
|
||||
});
|
||||
|
||||
// ❌ 错误:直接SQL访问public(不会发生,因为表不在public)
|
||||
await prisma.$queryRaw`SELECT * FROM public.literatures`;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔮 未来迁移策略
|
||||
|
||||
### 对于ASL模块
|
||||
|
||||
**推荐策略**:继续使用手动SQL脚本
|
||||
|
||||
**原因**:
|
||||
1. ✅ Public schema的历史遗留问题短期无法解决
|
||||
2. ✅ 手动脚本更安全、可控
|
||||
3. ✅ 避免意外影响其他模块
|
||||
4. ✅ 便于代码审查和审计
|
||||
|
||||
**操作流程**:
|
||||
|
||||
```bash
|
||||
# 1. 修改 Prisma Schema
|
||||
# backend/prisma/schema.prisma
|
||||
|
||||
# 2. 编写手动SQL脚本
|
||||
# backend/prisma/migrations/manual_xxx.sql
|
||||
|
||||
# 3. 执行脚本(只操作asl_schema)
|
||||
Get-Content manual_xxx.sql | docker exec -i ai-clinical-postgres psql ...
|
||||
|
||||
# 4. 验证结果
|
||||
docker exec ai-clinical-postgres psql ... -c "\dt asl_schema.*"
|
||||
|
||||
# 5. 生成Prisma Client
|
||||
npx prisma generate
|
||||
|
||||
# 6. 提交Git
|
||||
git add .
|
||||
git commit -m "feat(asl): add xxx tables for xxx feature"
|
||||
```
|
||||
|
||||
**SQL脚本模板**:
|
||||
|
||||
```sql
|
||||
-- 只操作asl_schema,不影响其他schema
|
||||
ALTER TABLE asl_schema.xxx ADD COLUMN IF NOT EXISTS ...;
|
||||
CREATE TABLE IF NOT EXISTS asl_schema.xxx (...);
|
||||
CREATE INDEX IF NOT EXISTS idx_xxx ON asl_schema.xxx(...);
|
||||
```
|
||||
|
||||
### 对于其他模块
|
||||
|
||||
**问题所有者**:各模块开发团队
|
||||
|
||||
**建议操作**(由各模块团队自行决定):
|
||||
1. 检查 `public` schema中是否有本模块的表
|
||||
2. 对比数据差异(`public` vs 正确schema)
|
||||
3. 决策是否需要数据迁移或清理
|
||||
4. 执行清理操作(风险自负)
|
||||
|
||||
**ASL团队立场**:
|
||||
- 🔵 不主动清理其他模块的public表
|
||||
- 🔵 不对其他模块数据安全负责
|
||||
- 🔵 专注于asl_schema的质量和稳定性
|
||||

## 📊 数据完整性验证
|
||||
|
||||
### ASL模块数据关系图
|
||||
|
||||
```
|
||||
asl_schema.screening_projects (项目)
|
||||
↓ 1:N
|
||||
asl_schema.literatures (文献)
|
||||
↓ 1:1 ↓ 1:1
|
||||
asl_schema.screening_results asl_schema.fulltext_screening_results

|
||||
```
|
||||
|
||||
### 外键约束验证
|
||||
|
||||
```sql
|
||||
-- 验证所有外键都指向asl_schema内部
|
||||
SELECT
|
||||
tc.constraint_name,
|
||||
tc.table_name,
|
||||
kcu.column_name,
|
||||
ccu.table_name AS foreign_table_name,
|
||||
ccu.column_name AS foreign_column_name
|
||||
FROM information_schema.table_constraints AS tc
|
||||
JOIN information_schema.key_column_usage AS kcu
|
||||
ON tc.constraint_name = kcu.constraint_name
|
||||
JOIN information_schema.constraint_column_usage AS ccu
|
||||
ON ccu.constraint_name = tc.constraint_name
|
||||
WHERE tc.constraint_type = 'FOREIGN KEY'
|
||||
AND tc.table_schema = 'asl_schema'
|
||||
ORDER BY tc.table_name;
|
||||
|
||||
-- 预期结果:
|
||||
-- ✅ 所有FK的 foreign_table_name 都在 asl_schema 中
|
||||
-- ✅ 没有跨schema引用
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎯 关键结论
|
||||
|
||||
### ✅ ASL模块:完全健康
|
||||
|
||||
1. **Schema隔离**:100%正确,所有表都在 `asl_schema`
|
||||
2. **数据管理**:无数据泄漏到 `public`
|
||||
3. **代码规范**:所有访问路径正确
|
||||
4. **迁移策略**:手动SQL脚本,安全可控
|
||||
|
||||
### ⚠️ 系统级问题:Public Schema污染
|
||||
|
||||
1. **问题性质**:历史遗留,与ASL无关
|
||||
2. **影响范围**:AIA、PKB、Platform模块
|
||||
3. **解决责任**:各模块团队自行处理
|
