# 冗餘UserLevel/WordLevel欄位移除完成報告
|
||||
|
||||
## 📋 **執行總結**
|
||||
**執行時間**: 2025-09-26
|
||||
**狀態**: ✅ **完全成功**
|
||||
**架構**: 純CEFR字符串架構
|
||||
**前端**: http://localhost:3002
|
||||
**後端**: http://localhost:5008
|
||||
|
||||
---
|
||||
|
||||
## 🎯 **移除目標達成**
|
||||
|
||||
### **✅ 消除資料重複問題**
|
||||
```sql
|
||||
-- 移除前：重複存儲
|
||||
users.english_level: "A2" (主要)
|
||||
flashcards.UserLevel: 50 (冗餘) ← 已移除
|
||||
flashcards.difficulty_level: "A2" (主要)
|
||||
flashcards.WordLevel: 35 (冗餘) ← 已移除
|
||||
|
||||
-- 移除後：純CEFR架構
|
||||
users.english_level: "A2" (唯一來源)
|
||||
flashcards.difficulty_level: "A2" (唯一來源)
|
||||
```
|
||||
|
||||
### **✅ 程式碼簡化成果**
|
||||
- **FlashcardsController**: 移除數值欄位初始化邏輯
|
||||
- **SpacedRepetitionService**: 移除批量初始化程式碼
|
||||
- **前端接口**: 移除數值欄位映射
|
||||
- **資料庫模型**: 移除冗餘屬性定義
|
||||
|
||||
---
|
||||
|
||||
## 🔧 **具體實施成果**
|
||||
|
||||
### **Phase 1: 後端資料庫清理** ✅ **完成**
|
||||
|
||||
#### **1. 資料庫遷移執行**
|
||||
```bash
|
||||
✅ 創建遷移: dotnet ef migrations add RemoveRedundantLevelFields
|
||||
✅ 執行遷移: dotnet ef database update
|
||||
✅ 欄位移除: UserLevel, WordLevel從flashcards表移除
|
||||
```
|
||||
|
||||
#### **2. Flashcard模型更新**
|
||||
```csharp
|
||||
// 移除前：
|
||||
public int UserLevel { get; set; } = 50;
|
||||
public int WordLevel { get; set; } = 50;
|
||||
|
||||
// 移除後：
|
||||
// UserLevel和WordLevel已移除 - 改用即時CEFR轉換
|
||||
```
|
||||
|
||||
#### **3. Controller邏輯清理**
|
||||
```csharp
|
||||
// 移除前：數值欄位初始化
|
||||
if (nextCard.UserLevel == 0) nextCard.UserLevel = ...;
|
||||
if (nextCard.WordLevel == 0) nextCard.WordLevel = ...;
|
||||
|
||||
// 移除後：
|
||||
// UserLevel和WordLevel欄位已移除 - 改用即時CEFR轉換
|
||||
```
|
||||
|
||||
### **Phase 2: 前端接口適配** ✅ **完成**
|
||||
|
||||
#### **1. API服務層更新**
|
||||
```typescript
|
||||
// 移除前：包含數值欄位映射
|
||||
userLevel: card.userLevel || 50,
|
||||
wordLevel: card.wordLevel || 50,
|
||||
|
||||
// 移除後：
|
||||
// 智能複習擴展欄位 (數值欄位已移除，改用即時CEFR轉換)
|
||||
```
|
||||
|
||||
#### **2. 接口定義簡化**
|
||||
```typescript
|
||||
// 移除前：
|
||||
interface ExtendedFlashcard {
|
||||
userLevel?: number;
|
||||
wordLevel?: number;
|
||||
}
|
||||
|
||||
// 移除後：
|
||||
interface ExtendedFlashcard {
|
||||
// 注意：userLevel和wordLevel已移除，改用即時CEFR轉換
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧪 **功能驗證結果**
|
||||
|
||||
### **✅ API測試通過**
|
||||
```bash
|
||||
✅ GET /flashcards/due:
|
||||
- success: true, count: 5
|
||||
- hasUserLevel: false, hasWordLevel: false
|
||||
- 確認數值欄位已完全移除
|
||||
|
||||
✅ POST /flashcards/{id}/optimal-review-mode:
|
||||
- userCEFR: "A2" → 智能選擇: "sentence-reorder"
|
||||
- adaptationContext: "適中詞彙"
|
||||
- 純CEFR字符串智能選擇100%正常
|
||||
```
|
||||
|
||||
### **✅ 即時轉換驗證**
|
||||
```csharp
|
||||
// 後端日誌確認：
|
||||
CEFR converted to levels: A2→35, A2→35
|
||||
Selected mode: sentence-reorder, context: 適中詞彙
|
||||
```
|
||||
|
||||
### **✅ 前端功能正常**
|
||||
- 學習頁面載入正常
|
||||
- 四情境對照表顯示正確
|
||||
- 智能適配完全正常
|
||||

# 移除冗餘UserLevel/WordLevel欄位和程式碼計劃
|
||||
|
||||
## 🎯 **目標**
|
||||
徹底移除冗餘的數值欄位，簡化資料庫結構，實現純CEFR字符串架構，消除資料重複問題。
|
||||
|
||||
---
|
||||
|
||||
## 📊 **現況分析**
|
||||
|
||||
### **重複資料確認**
|
||||
```sql
|
||||
-- 用戶程度重複存儲 ❌
|
||||
users.english_level: "A2" (主要，標準CEFR)
|
||||
flashcards.UserLevel: 50 (冗餘，數值緩存)
|
||||
|
||||
-- 詞彙難度重複存儲 ❌
|
||||
flashcards.difficulty_level: "A2" (主要，標準CEFR)
|
||||
flashcards.WordLevel: 35 (冗餘，數值緩存)
|
||||
```
|
||||
|
||||
### **冗餘程度評估**
|
||||
- **智能選擇**: ✅ 已改為即時CEFR轉換，不使用存儲數值
|
||||
- **四情境判斷**: ✅ 使用即時轉換的數值進行運算
|
||||
- **API回應**: ⚠️ 仍包含數值欄位（僅為前端相容）
|
||||
- **舊資料處理**: ⚠️ 防止數值為0的初始化邏輯

||||

|
||||
|
||||
## 📋 **詳細移除計劃**
|
||||
|
||||
### **Phase 1: 後端資料庫和模型清理** ⏱️ 1天
|
||||
|
||||
#### **1.1 創建資料庫遷移**
|
||||
```bash
|
||||
cd backend/DramaLing.Api
|
||||
dotnet ef migrations add RemoveRedundantLevelFields
|
||||
```
|
||||
|
||||
**Migration內容**:
|
||||
```sql
|
||||
ALTER TABLE flashcards DROP COLUMN UserLevel;
|
||||
ALTER TABLE flashcards DROP COLUMN WordLevel;
|
||||
```
|
||||
|
||||
#### **1.2 更新Flashcard模型**
|
||||
**檔案**: `Models/Entities/Flashcard.cs`
|
||||
```csharp
|
||||
// 移除這兩個屬性：
|
||||
// [Range(1, 100)]
|
||||
// public int UserLevel { get; set; } = 50;
|
||||
//
|
||||
// [Range(1, 100)]
|
||||
// public int WordLevel { get; set; } = 50;
|
||||
```
|
||||
|
||||
#### **1.3 清理配置選項**
|
||||
**檔案**: `appsettings.json`
|
||||
```json
|
||||
{
|
||||
"SpacedRepetition": {
|
||||
// 移除 "DefaultUserLevel": 50
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**檔案**: `Models/Configuration/SpacedRepetitionOptions.cs`
|
||||
```csharp
|
||||
// 移除 DefaultUserLevel 屬性
|
||||
```
|
||||
|
||||
### **Phase 2: 後端API和服務清理** ⏱️ 1天
|
||||
|
||||
#### **2.1 清理FlashcardsController**
|
||||
**檔案**: `Controllers/FlashcardsController.cs`
|
||||
|
||||
**移除數值欄位初始化**:
|
||||
```csharp
|
||||
// 移除 lines 508-512:
|
||||
// if (nextCard.UserLevel == 0)
|
||||
// nextCard.UserLevel = CEFRMappingService.GetDefaultUserLevel();
|
||||
// if (nextCard.WordLevel == 0)
|
||||
// nextCard.WordLevel = CEFRMappingService.GetWordLevel(nextCard.DifficultyLevel);
|
||||
```
|
||||
|
||||
**簡化API回應**:
|
||||
```csharp
|
||||
var response = new
|
||||
{
|
||||
// 移除 nextCard.UserLevel, nextCard.WordLevel
|
||||
// 保留 nextCard.DifficultyLevel (CEFR字符串)
|
||||
};
|
||||
```
|
||||
|
||||
#### **2.2 清理SpacedRepetitionService**
|
||||
**檔案**: `Services/SpacedRepetitionService.cs`
|
||||
|
||||
**移除批量初始化邏輯**:
|
||||
```csharp
|
||||
// 移除 lines 141-149:
|
||||
// foreach (var card in dueCards.Where(c => c.WordLevel == 0))
|
||||
// {
|
||||
// card.WordLevel = CEFRMappingService.GetWordLevel(card.DifficultyLevel);
|
||||
// if (card.UserLevel == 0)
|
||||
// card.UserLevel = _options.DefaultUserLevel;
|
||||
// }
|
||||
```
|
||||
|
||||
#### **2.3 清理QuestionGeneratorService**
|
||||
**檔案**: `Services/QuestionGeneratorService.cs`
|
||||
|
||||
**移除數值版本的方法** (如果存在):
|
||||
```csharp
|
||||
// 檢查並移除任何直接使用數值參數的方法
|
||||
```
|
||||
|
||||
### **Phase 3: 前端適配調整** ⏱️ 0.5天
|
||||
|
||||
#### **3.1 更新前端API服務**
|
||||
**檔案**: `frontend/lib/services/flashcards.ts`
|
||||
|
||||
**移除數值欄位映射**:
|
||||
```typescript
|
||||
const flashcards = response.data.map((card: any) => ({
|
||||
// 移除這兩行：
|
||||
// userLevel: card.userLevel || 50,
|
||||
// wordLevel: card.wordLevel || 50,
|
||||
}));
|
||||
```
|
||||
|
||||
#### **3.2 更新前端接口定義**
|
||||
**檔案**: `frontend/app/learn/page.tsx`
|
||||
|
||||
**簡化ExtendedFlashcard**:
|
||||
```typescript
|
||||
interface ExtendedFlashcard extends Omit<Flashcard, 'nextReviewDate'> {
|
||||
// 移除：
|
||||
// userLevel?: number;
|
||||
// wordLevel?: number;
|
||||
|
||||
nextReviewDate?: string;
|
||||
// ...其他實際需要的欄位
|
||||
}
|
||||
```
|
||||
|
||||
#### **3.3 更新前端顯示邏輯**
|
||||
**全部改為CEFR字符串邏輯**:
|
||||
```typescript
|
||||
// 不再使用 currentCard.userLevel, currentCard.wordLevel
|
||||
// 改為：
|
||||
const userCEFR = localStorage.getItem('userEnglishLevel') || 'A2';
|
||||
const wordCEFR = currentCard.difficultyLevel || 'A2';
|
||||
```
|
||||
|
||||
### **Phase 4: API接口純化** ⏱️ 0.5天
|
||||
|
||||
#### **4.1 移除API回應中的數值欄位**
|
||||
**所有相關API端點**:
|
||||
- `GET /flashcards/due`
|
||||
- `GET /flashcards/next-review`
|
||||
- `GET /flashcards/{id}`
|
||||
|
||||
**移除回應中的**:
|
||||
```json
|
||||
{
|
||||
// 移除 "userLevel": 50,
|
||||
// 移除 "wordLevel": 35,
|
||||
"difficultyLevel": "A2" // 保留CEFR字符串
|
||||
}
|
||||
```
|
||||
|
||||
#### **4.2 更新API文檔**
|
||||
- 移除數值欄位的相關描述
|
||||
- 更新為純CEFR架構文檔
|
||||
|
||||
### **Phase 5: 測試和驗證** ⏱️ 0.5天

## ⚠️ **風險管理**
|
||||
|
||||
### **風險等級**: 🟢 **低風險**
|
||||
- CEFR轉換邏輯已穩定運行
|
||||
- 即時轉換性能優異
|
||||
- 不影響用戶體驗
|
||||
|
||||
### **緩解措施**
|
||||
- 保留migration回滾腳本
|
||||
- 分階段實施，逐步驗證
|
||||
- 保持完整測試覆蓋
|
||||
- 監控性能指標
|
||||
|
||||
### **回滾計劃**
|
||||
如有問題可快速回滾：
|
||||
```sql
|
||||
-- 回滾migration恢復欄位
|
||||
dotnet ef database update PreviousMigration
|
||||
```

## 🚀 **實施建議**
|
||||
|
||||
### **推薦立即實施**
|
||||
1. **技術債務清理**: 消除設計上的冗餘
|
||||
2. **標準化架構**: 完全符合CEFR國際標準
|
||||
3. **長期維護**: 降低未來開發和維護成本
|
||||
4. **代碼品質**: 提升整體架構清潔度
|
||||
|
||||
### **實施順序**
|
||||
1. **後端清理** → **前端適配** → **測試驗證**
|
||||
2. 可隨時暫停，每個階段都有明確的檢查點
|
||||
3. 出現問題立即回滾，影響可控
|
||||
|
||||
**建議：開始實施此清理計劃，徹底解決資料重複問題！** 🎯
