feat: 练习进度系统重构和AI评分持久化
重大改进： - 练习进度模型优化：从"每题一条记录"改为"每用户每类型一条记录"，提升性能和数据管理 - 完全基于后端数据库恢复答题进度，移除 localStorage 依赖，提高可靠性 - AI评分结果持久化：在答题记录中保存AI评分、评语和建议，支持历史查看 后端改进： - 新增 /api/practice/progress 接口获取练习进度（支持按类型筛选） - 新增 /api/practice/progress 接口清除练习进度（支持按类型清除） - PracticeProgress 模型重构：添加 current_question_id 和 user_answer_records 字段 - UserAnswerRecord 模型增强：添加 ai_score、ai_feedback、ai_suggestion 字段 - 提交答案时自动保存AI评分到数据库 前端优化： - 答题进度完全从后端加载，移除 localStorage 备份逻辑 - 修复判断题答案格式转换问题（boolean -> string） - 优化随机模式：首次答题时随机选择起始题目 - 改进答题历史显示：显示答题序号和历史答案标识 - 已答题目切换时保持答案和结果显示状态 - 清除进度时支持按类型清除（而非清空所有） 技术优化： - 统一索引策略：从 idx_user_question 改为 idx_user_type - JSON 字段类型从 jsonp 改为 jsonb（PostgreSQL 性能优化） - 增加详细的日志记录，便于调试和追踪 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# 修复 practice_progress 表索引问题
|
||||
|
||||
## 问题描述
|
||||
|
||||
在测试中发现，除了单选题（multiple-choice）能正常插入进度数据外，其他类型的题目无法插入数据到 `practice_progress` 表。
|
||||
|
||||
## 问题原因
|
||||
|
||||
### 错误的索引定义
|
||||
|
||||
**之前的模型定义**（错误）：
|
||||
```go
|
||||
type PracticeProgress struct {
|
||||
ID int64 `gorm:"primarykey" json:"id"`
|
||||
CurrentQuestionID int64 `gorm:"not null" json:"current_question_id"`
|
||||
UserID int64 `gorm:"not null;uniqueIndex:idx_user_question" json:"user_id"` // ❌ 只在 user_id 上建索引
|
||||
Type string `gorm:"type:varchar(255);not null" json:"type"`
|
||||
UserAnswerRecords datatypes.JSON `gorm:"type:jsonp" json:"answers"`
|
||||
}
|
||||
```
|
||||
|
||||
**问题**：
|
||||
- 唯一索引 `idx_user_question` 只在 `user_id` 字段上
|
||||
- 同一用户只能有一条进度记录
|
||||
- 当用户答第二种题型时，因为 `user_id` 重复，插入失败
|
||||
- 日志中应该会看到类似错误：`duplicate key value violates unique constraint "idx_user_question"`
|
||||
|
||||
### 正确的索引定义
|
||||
|
||||
**修复后的模型定义**（正确）：
|
||||
```go
|
||||
type PracticeProgress struct {
|
||||
ID int64 `gorm:"primarykey" json:"id"`
|
||||
CurrentQuestionID int64 `gorm:"not null" json:"current_question_id"`
|
||||
UserID int64 `gorm:"not null;uniqueIndex:idx_user_type" json:"user_id"` // ✅ 联合索引
|
||||
Type string `gorm:"type:varchar(255);not null;uniqueIndex:idx_user_type" json:"type"` // ✅ 联合索引
|
||||
UserAnswerRecords datatypes.JSON `gorm:"type:jsonb" json:"answers"`
|
||||
}
|
||||
```
|
||||
|
||||
**改进**：
|
||||
- 唯一索引 `idx_user_type` 是 `(user_id, type)` 的联合索引
|
||||
- 同一用户可以有多条进度记录（每种题型一条）
|
||||
- 例如：用户1 可以有 `(1, "multiple-choice")` 和 `(1, "true-false")` 两条记录
|
||||
|
||||
## 解决方案
|
||||
|
||||
### 方案1：使用 GORM 自动迁移（推荐）
|
||||
|
||||
1. **停止当前服务**
|
||||
|
||||
2. **删除旧表并重建**（谨慎：会丢失所有进度数据）
|
||||
|
||||
连接到 PostgreSQL 数据库：
|
||||
```bash
|
||||
psql -U your_username -d your_database
|
||||
```
|
||||
|
||||
执行：
|
||||
```sql
|
||||
DROP TABLE IF EXISTS practice_progress;
|
||||
```
|
||||
|
||||
3. **重启服务，GORM 会自动创建正确的表结构**
|
||||
```bash
|
||||
.\bin\server.exe
|
||||
```
|
||||
|
||||
### 方案2：手动修复索引（保留数据）
|
||||
|
||||
1. **连接到 PostgreSQL 数据库**：
|
||||
```bash
|
||||
psql -U your_username -d your_database
|
||||
```
|
||||
|
||||
2. **执行 SQL 脚本**：
|
||||
```bash
|
||||
\i scripts/fix_practice_progress_index.sql
|
||||
```
|
||||
|
||||
或手动执行：
|
||||
```sql
|
||||
-- 删除旧索引
|
||||
DROP INDEX IF EXISTS idx_user_question;
|
||||
|
||||
-- 创建新索引
|
||||
CREATE UNIQUE INDEX IF NOT EXISTS idx_user_type ON practice_progress(user_id, type);
|
||||
```
|
||||
|
||||
3. **验证索引**：
|
||||
```sql
|
||||
SELECT indexname, indexdef
|
||||
FROM pg_indexes
|
||||
WHERE tablename = 'practice_progress';
|
||||
```
|
||||
|
||||
应该看到：
|
||||
```
|
||||
indexname | indexdef
|
||||
--------------|--------------------------------------------------
|
||||
idx_user_type | CREATE UNIQUE INDEX idx_user_type ON practice_progress USING btree (user_id, type)
|
||||
```
|
||||
|
||||
4. **检查现有数据是否有冲突**：
|
||||
```sql
|
||||
SELECT user_id, type, COUNT(*)
|
||||
FROM practice_progress
|
||||
GROUP BY user_id, type
|
||||
HAVING COUNT(*) > 1;
|
||||
```
|
||||
|
||||
如果有重复数据，需要手动清理：
|
||||
```sql
|
||||
-- 保留每组的最新记录，删除旧记录
|
||||
DELETE FROM practice_progress a
|
||||
WHERE id NOT IN (
|
||||
SELECT MAX(id)
|
||||
FROM practice_progress b
|
||||
WHERE a.user_id = b.user_id AND a.type = b.type
|
||||
);
|
||||
```
|
||||
|
||||
## 验证修复
|
||||
|
||||
### 1. 检查表结构
|
||||
```sql
|
||||
\d practice_progress
|
||||
```
|
||||
|
||||
应该看到：
|
||||
```
|
||||
Indexes:
|
||||
"practice_progress_pkey" PRIMARY KEY, btree (id)
|
||||
"idx_user_type" UNIQUE, btree (user_id, type)
|
||||
```
|
||||
|
||||
### 2. 测试插入不同题型
|
||||
|
||||
**测试步骤**：
|
||||
1. 登录系统
|
||||
2. 选择"单选题"，答几道题
|
||||
3. 切换到"多选题"，答几道题
|
||||
4. 切换到"判断题"，答几道题
|
||||
|
||||
**检查数据库**：
|
||||
```sql
|
||||
SELECT id, user_id, type, current_question_id
|
||||
FROM practice_progress
|
||||
WHERE user_id = 1; -- 替换为你的用户ID
|
||||
```
|
||||
|
||||
应该看到多条记录：
|
||||
```
|
||||
id | user_id | type | current_question_id
|
||||
---|---------|---------------------|--------------------
|
||||
1 | 1 | multiple-choice | 157
|
||||
2 | 1 | multiple-selection | 45
|
||||
3 | 1 | true-false | 10
|
||||
```
|
||||
|
||||
### 3. 检查后端日志
|
||||
|
||||
如果之前有错误，应该不再看到类似日志：
|
||||
```
|
||||
保存练习进度失败: duplicate key value violates unique constraint "idx_user_question"
|
||||
```
|
||||
|
||||
## 其他注意事项
|
||||
|
||||
1. **JSONB vs JSONP**：
|
||||
- 修改了 `UserAnswerRecords` 的类型从 `jsonp` 改为 `jsonb`
|
||||
- `jsonb` 是正确的 PostgreSQL JSON 类型
|
||||
- 性能更好，支持索引
|
||||
|
||||
2. **数据备份**：
|
||||
- 在修改表结构前，建议备份数据：
|
||||
```bash
|
||||
pg_dump -U your_username -d your_database -t practice_progress > backup_practice_progress.sql
|
||||
```
|
||||
|
||||
3. **回滚方案**：
|
||||
- 如果需要回滚，可以恢复备份：
|
||||
```bash
|
||||
psql -U your_username -d your_database < backup_practice_progress.sql
|
||||
```

||||
