refactor: 完全清空後端複習系統為重新實施做準備
- 刪除所有智能複習相關服務和控制器 - 移除 StudyController, StudySessionController - 刪除 SpacedRepetitionService, ReviewTypeSelectorService 等服務 - 清理 SpacedRepetition DTO 和配置文件 - 簡化 Flashcard 實體，移除所有複習相關屬性 - 移除 StudyRecord, StudySession, StudyCard 實體 - 清理 Program.cs 服務註冊和 appsettings 配置 - 為組件化重新實施提供純淨的代碼基礎 清空效果: - StudyController: 583行 → 0行 (完全刪除) - FlashcardsController: 461行 → 271行 (純粹CRUD) - 複習服務: 5個 → 0個 (完全移除) - 系統複雜度: 大幅降低，架構清晰 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# 後端複習系統清空執行計劃
|
||||
|
||||
**目標**: 完全移除當前後端複雜的複習系統程式碼，準備重新實施簡潔版本
|
||||
**日期**: 2025-09-29
|
||||
**執行範圍**: DramaLing.Api 後端專案
|
||||
**風險等級**: 🟡 中等 (需要仔細執行以避免破壞核心功能)
|
||||
|
||||
---
|
||||
|
||||
## 🎯 **清空目標與範圍**
|
||||
|
||||
### **清空目標**
|
||||
1. **移除複雜的智能複習邏輯**: 包含 Session 概念、複雜隊列管理
|
||||
2. **保留核心詞卡功能**: 基本 CRUD 和簡單統計
|
||||
3. **為重新實施做準備**: 清潔的代碼基礎
|
||||
|
||||
### **保留功能**
|
||||
- ✅ 詞卡基本 CRUD (FlashcardsController)
|
||||
- ✅ 用戶認證 (AuthController)
|
||||
- ✅ AI 分析服務 (AIController)
|
||||
- ✅ 音訊服務 (AudioController)
|
||||
- ✅ 圖片生成 (ImageGenerationController)
|
||||
- ✅ 基礎統計 (StatsController)
|
||||
|
||||
---
|
||||
|
||||
## 🗄️ **資料庫結構盤點**
|
||||
|
||||
### **複習系統相關資料表**
|
||||
```sql
|
||||
📊 當前資料庫表結構分析：
|
||||
|
||||
✅ 需要保留的核心表：
|
||||
├── user_profiles 用戶基本資料
|
||||
├── flashcards 詞卡核心資料 (需簡化)
|
||||
├── study_records 學習記錄 (需簡化)
|

├── daily_stats 每日統計
|
||||
├── audio_cache 音訊快取
|
||||
├── example_images 例句圖片
|
||||
├── flashcard_example_images 詞卡圖片關聯
|
||||
├── image_generation_requests 圖片生成請求
|
||||
├── options_vocabularies 選項詞彙庫
|
||||
├── error_reports 錯誤報告
|
||||
└── sentence_analysis_cache 句子分析快取
|
||||
|
||||
❌ 需要處理的複習相關表：
|
||||
├── study_sessions 學習會話表 🗑️ 刪除
|
||||
├── study_cards 會話詞卡表 🗑️ 刪除
|
||||
├── test_results 測驗結果表 🗑️ 刪除
|
||||
└── pronunciation_assessments 發音評估 ⚠️ 檢查關聯
|
||||
```
|
||||
|
||||
### **資料庫遷移文件**
|

|
||||
└── 其他遷移文件 ✅ 保留
|
||||
```
|
||||
|
||||
### **資料庫清理策略**
|
||||
1. **StudyRecord 表處理**:
|
||||
- ✅ **保留基本結構**: 作為簡化的學習記錄
|
||||
- 🔧 **移除複雜欄位**: SM-2 相關的追蹤欄位
|
||||
- ⚠️ **保留核心欄位**: user_id, flashcard_id, study_mode, is_correct, studied_at
|
||||
|
||||
2. **複雜表結構移除**:
|
||||
- 🗑️ **study_sessions**: 完全移除 (Session 概念)
|
||||
- 🗑️ **study_cards**: 完全移除 (Session 相關)
|
||||
- 🗑️ **test_results**: 完全移除 (與 StudyRecord 重複)
|
||||
|
||||
3. **遷移文件處理**:
|
||||
- 📝 **創建回滾遷移**: 移除 study_sessions, study_cards, test_results 表
|
||||
- ✅ **保留核心遷移**: StudyRecord 基本結構保留

|

|
||||
## 🔍 **詳細清空步驟**
|
||||
|
||||
### **第一階段：停止服務並備份**
|
||||
1. **停止當前運行的服務**
|
||||
```bash
|
||||
# 停止所有後端服務
|
||||
pkill -f "dotnet run"
|
||||
```
|
||||
|
||||
2. **創建備份分支** (可選)
|
||||
```bash
|
||||
git checkout -b backup/before-review-cleanup
|
||||
git add .
|
||||
git commit -m "backup: 清空前的複習系統狀態備份"
|
||||
```
|
||||
|
||||
### **第二階段：刪除服務層文件**
|
||||
```bash
|
||||
# 刪除智能複習服務
|
||||
rm Services/SpacedRepetitionService.cs
|
||||
rm Services/ReviewTypeSelectorService.cs
|
||||
rm Services/ReviewModeSelector.cs
|
||||
|
||||
# 檢查並決定是否刪除
|
||||
# rm Services/QuestionGeneratorService.cs # 可能被選項詞彙庫使用
|
||||
# rm Services/BlankGenerationService.cs # 可能被其他功能使用
|
||||
```
|
||||
|
||||
### **第三階段：刪除 DTO 和配置文件**
|
||||
```bash
|
||||
# 刪除整個 SpacedRepetition DTO 資料夾
|
||||
rm -rf Models/DTOs/SpacedRepetition/
|
||||
|
||||
# 刪除配置文件
|
||||
rm Models/Configuration/SpacedRepetitionOptions.cs
|
||||
```
|
||||
|
||||
### **第四階段：簡化 StudyController**
|
||||
需要手動編輯 `Controllers/StudyController.cs`：
|
||||
```csharp
|
||||
// 移除的內容：
|
||||
- 智能複習服務依賴注入 (ISpacedRepetitionService, IReviewTypeSelectorService 等)
|
||||
- 智能複習 API 方法 (GetDueCards, GetNextReview, GetOptimalReviewMode, GenerateQuestion, SubmitReview)
|
||||
- 複雜的 Session 相關邏輯
|
||||
|
||||
// 保留的內容：
|
||||
- 基礎統計 (GetStudyStats)
|
||||
- 測驗記錄 (RecordTestCompletion, GetCompletedTests)
|
||||
- 基礎認證和日誌功能
|
||||
```
|
||||
|
||||
### **第五階段：清理 Program.cs 服務註冊**
|
||||
```csharp
|
||||
// 移除的服務註冊：
|
||||
// builder.Services.AddScoped<ISpacedRepetitionService, SpacedRepetitionService>();
|
||||
// builder.Services.AddScoped<IReviewTypeSelectorService, ReviewTypeSelectorService>();
|
||||
// builder.Services.AddScoped<IQuestionGeneratorService, QuestionGeneratorService>();
|
||||
// builder.Services.Configure<SpacedRepetitionOptions>(...);
|
||||
```
|
||||
|
||||
### **第六階段：簡化資料模型**
|
||||
1. **簡化 Flashcard.cs**
|
||||
```csharp
|
||||
// 移除的屬性：
|
||||
- ReviewHistory
|
||||
- LastQuestionType
|
||||
- 複雜的 SM-2 算法屬性 (可選保留基礎的)
|
||||
|
||||
// 保留的屬性：
|
||||
- 基本詞卡內容 (Word, Translation, Definition 等)
|
||||
- 基礎學習狀態 (MasteryLevel, TimesReviewed)
|
||||
- 基礎複習間隔 (NextReviewDate, IntervalDays)
|
||||
```
|
||||
|
||||
2. **簡化 StudyRecord.cs**
|
||||
```csharp
|
||||
// 保留簡化版本：
|
||||
- 基本測驗記錄 (FlashcardId, TestType, IsCorrect)
|
||||
- 移除複雜的 SM-2 追蹤參數
|
||||
```
|
||||
|
||||
### **第七階段：資料庫結構清理**
|
||||
|
||||
#### **7.1 清理 DramaLingDbContext.cs**
|
||||
```csharp
|
||||
// 移除的 DbSet：
|
||||
- DbSet<StudySession> StudySessions 🗑️ 刪除
|
||||
- DbSet<StudyCard> StudyCards 🗑️ 刪除
|
||||
- DbSet<TestResult> TestResults 🗑️ 刪除
|
||||
|
||||
// 移除的 ToTable 配置：
|
||||
- .ToTable("study_sessions") 🗑️ 刪除
|
||||
- .ToTable("study_cards") 🗑️ 刪除
|
||||
- .ToTable("test_results") 🗑️ 刪除
|
||||
|
||||
// 移除的關聯配置：
|
||||
- StudySession 與 User 的關聯
|
||||
- StudyCard 與 StudySession 的關聯
|
||||
- TestResult 與 StudyCard 的關聯
|
||||
- PronunciationAssessment 與 StudySession 的關聯
|
||||
|
||||
// 簡化 StudyRecord 配置：
|
||||
- 移除複雜的 SM-2 追蹤欄位配置
|
||||
- 保留基本的 user_id, flashcard_id, study_mode 索引
|
||||
```
|
||||
|
||||
#### **7.2 創建資料庫清理遷移**
|
||||
```bash
|
||||
# 創建新的遷移來移除複雜表結構
|
||||
dotnet ef migrations add RemoveComplexStudyTables
|
||||
|
||||
# 在遷移中執行：
|
||||
migrationBuilder.DropTable("study_sessions");
|
||||
migrationBuilder.DropTable("study_cards");
|
||||
migrationBuilder.DropTable("test_results");
|
||||
|
||||
# 移除 PronunciationAssessment 中的 StudySessionId 欄位
|
||||
migrationBuilder.DropColumn("study_session_id", "pronunciation_assessments");
|
||||
```
|
||||
|
||||
#### **7.3 清理配置文件**
|
||||
```json
|
||||
// appsettings.json - 移除的配置段落：
|
||||
- "SpacedRepetition": { ... } 🗑️ 完全移除
|
||||
```
|
||||
|
||||
#### **7.4 簡化 Flashcard 實體**
|
||||
```csharp
|
||||
// Flashcard.cs - 移除的複習相關屬性：
|
||||
- ReviewHistory (JSON 複習歷史) 🗑️ 移除
|
||||
- LastQuestionType 🗑️ 移除
|
||||
- 複雜的 SM-2 追蹤欄位 (可選保留基礎的) ⚠️ 檢查
|
||||
|
||||
// 保留的基本屬性：
|
||||
- EasinessFactor, Repetitions, IntervalDays ✅ 保留 (基礎複習間隔)
|
||||
- NextReviewDate, MasteryLevel ✅ 保留 (基本狀態)
|
||||
- TimesReviewed, TimesCorrect ✅ 保留 (統計)
|
||||
```

|
||||
## 🛡️ **風險控制措施**
|
||||
|
||||
### **清空前檢查**
|
||||
1. **確認無前端依賴**: 檢查前端是否調用即將刪除的 API
|
||||
2. **資料備份**: 確保重要資料已備份
|
||||
3. **服務停止**: 確保所有相關服務已停止
|
||||
|
||||
### **分階段執行**
|
||||
1. **先註解服務註冊**: 在 Program.cs 中註解掉服務，確保編譯通過
|
||||
2. **逐步刪除文件**: 按依賴關係順序刪除
|
||||
3. **驗證編譯**: 每階段後驗證系統可編譯
|
||||
4. **功能測試**: 確保保留功能正常運作
|
||||
|
||||
### **回滾準備**
|
||||
1. **Git 分支備份**: 清空前創建備份分支
|
||||
2. **關鍵文件備份**: 手動備份重要配置文件
|
||||
3. **快速恢復腳本**: 準備快速恢復命令
