# Fonrey — Public Schema 数据模型
|
||||
|
||||
> **作者**: Backend Architect
|
||||
> **版本**: v1.0
|
||||
> **日期**: 2026-04-24
|
||||
> **权威源**: 本文件是 `public` schema 所有表的唯一权威定义
|
||||
> **设计依据**: 系统管理模块 PRD（`PRD/系统管理/系统管理模块PRD.md`）
|
||||
> **索引文档**: [`DATA_MODEL.md §三`](./DATA_MODEL.md)（仅保留摘要索引，开发以本文件为准）
|

|
||||
|
||||
## 一、概览
|
||||
|
||||
`public` schema 存储**平台运营层**数据，与各租户的业务 schema 完全隔离。
|
||||
|
||||
### 架构定位
|
||||
|
||||
```
|
||||
PostgreSQL Instance
|
||||

|
||||

|
||||
│ ├── tenants 租户注册与生命周期
|
||||
│ ├── domains 域名路由
|
||||
│ ├── tenant_status_logs 状态变更审计
|
||||
│ ├── platform_admins 管理员账号
|
||||
│ ├── admin_mfa_devices TOTP 设备
|
||||
│ ├── admin_sessions 登录会话

|

## 三、关键约束与禁止操作
|
||||
|
||||
| 规则 | 说明 |
|
||||
|------|------|
|
||||
| `tenant_status_logs` append-only | 禁止 UPDATE / DELETE；状态机变更只追加新行 |
|
||||
| `platform_audit_logs` append-only | 禁止 UPDATE / DELETE；建议按月 RANGE 分区 |
|
||||
| `public.tenants.schema_name` 不可修改 | 创建后禁止 UPDATE，PG schema 绑定 |
|
||||
| `public.domains.domain` 不可修改 | 子域名创建后禁止 UPDATE |
|
||||
| `system_versions` 唯一 current | `idx_system_versions_current` 部分唯一索引保证全局只有一个 `status='current'` |
|
||||
| `backup_schedules.tenant_id` UNIQUE | 每个租户最多一条独立计划；`NULL` 全局计划由应用层保证唯一 |
|
||||
| `platform_admins` 与 `staff` 完全独立 | 不共享表、不共享 auth 系统 |
|
||||
| MFA 强制 | `platform_admins.mfa_enabled` 在首次 TOTP 确认后才变 TRUE；登录流必须检查 |
|
||||
| `admin_sessions` 30 分钟滚动超时 | 应用层每次活跃请求更新 `expires_at = NOW() + 30min` |
|
||||
|
||||
---
|
||||
|
||||
## 四、状态机

||||
|
||||
### 4.1 租户生命周期

**字段映射**：
|
||||
- `status` 枚举：`creating | active | suspended | pending_delete | deleted | failed`
|
||||
- `suspended_until = NULL`：永久挂起；`suspended_until IS NOT NULL`：Celery Beat 定时自动恢复
|
||||
- `deleted_at`：软删除时间戳；硬删除时物理删除整行

## 五、查询模式
|
||||
|
||||
### 5.1 常用查询
|
||||
|
||||
```sql
|
||||
-- 查询所有活跃租户
|
||||
SELECT id, name, plan, paid_until
|
||||
FROM public.tenants
|
||||
WHERE status = 'active'
|
||||
ORDER BY created_at DESC;
|
||||
|
||||
-- 查询即将到期的租户（7 天内）
|
||||
SELECT id, name, contact_email, paid_until
|
||||
FROM public.tenants
|
||||
WHERE status = 'active'
|
||||
AND paid_until BETWEEN CURRENT_DATE AND CURRENT_DATE + 7;
|
||||
|
||||
-- 查询灰度租户（canary 升级目标）
|
||||
SELECT id, schema_name, name
|
||||
FROM public.tenants
|
||||
WHERE is_canary = TRUE AND status = 'active';
|
||||
|
||||
-- 查询某租户所有状态变更历史
|
||||
SELECT from_status, to_status, reason, operator_name, created_at
|
||||
FROM public.tenant_status_logs
|
||||
WHERE tenant_id = $1
|
||||
ORDER BY created_at DESC;
|
||||
|
||||
-- 查询待自动恢复的挂起租户（Celery Beat 使用）
|
||||
SELECT id, schema_name, name
|
||||
FROM public.tenants
|
||||
WHERE status = 'suspended'
|
||||
AND suspended_until IS NOT NULL
|
||||
AND suspended_until <= NOW();
|
||||
|
||||
-- 查询某管理员近 30 天的审计记录
|
||||
SELECT action_type, target_type, target_name, result, created_at
|
||||
FROM public.platform_audit_logs
|
||||
WHERE operator_id = $1
|
||||
AND created_at >= NOW() - INTERVAL '30 days'
|
||||
ORDER BY created_at DESC;
|
||||
|
||||
-- 查询进行中的备份任务
|
||||
SELECT br.id, t.name AS tenant_name, br.trigger_type, br.started_at
|
||||
FROM public.backup_records br
|
||||
JOIN public.tenants t ON t.id = br.tenant_id
|
||||
WHERE br.status IN ('pending', 'in_progress')
|
||||
ORDER BY br.created_at DESC;
|
||||
```
|
||||
|
||||
### 5.2 禁止查询
|
||||
|
||||
| 禁止操作 | 原因 |
|
||||
|----------|------|
|
||||
| `UPDATE public.tenant_status_logs` | append-only 审计表 |
|
||||
| `DELETE FROM public.platform_audit_logs` | append-only 审计表 |
|
||||
| `UPDATE public.tenants SET schema_name = ...` | schema 名绑定 PG 物理 schema |
|
||||
| `UPDATE public.domains SET domain = ...` | 域名路由不可变 |
