charset=UTF-8 Content-Transfer-Encoding: 8bit 🎉 重大突破：FlashcardsController 成功整合圖片資訊 **核心整合功能**: - ✅ 修復EF Core關聯配置：解決FlashcardId1 shadow property衝突 - ✅ 擴展Flashcard實體：添加FlashcardExampleImages導航屬性 - ✅ 創建ExampleImageDto：完整的圖片資訊傳輸物件 - ✅ FlashcardsController圖片整合：API回應包含動態圖片資料 **資料結構擴展**: - ✅ hasExampleImage布林欄位：判斷詞卡是否有圖片 - ✅ primaryImageUrl字串欄位：主要圖片的完整URL - ✅ exampleImages陣列：支援多張圖片的完整資訊 - ✅ 圖片元數據：檔案大小、品質評分、創建時間 **系統穩定性保證**: - ✅ 向後相容性：不破壞現有詞卡功能 - ✅ 架構一致性：遵循專案EF Core模式 - ✅ 錯誤處理：完整的異常處理和日誌記錄 - ✅ 效能優化：AsNoTracking查詢優化 **驗證結果**: - ✅ 有圖片詞卡：正確返回圖片URL和資訊 - ✅ 無圖片詞卡：正確返回false和null值 - ✅ API穩定性：HTTP 500錯誤已修復 - ✅ 圖片URL生成：IImageStorageService整合成功 **技術債務處理**: - ✅ 漸進式整合：維持系統穩定優先原則 - ✅ 關聯映射修復：正確配置Flashcard ↔ ExampleImage關聯 - ✅ 依賴注入優化：FlashcardsController整合IImageStorageService - ✅ 查詢優化：Include + ThenInclude 正確載入關聯資料 前端現在可以完全依賴API資料，逐步取代硬編碼映射！ 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../Controllers/FlashcardsController.cs | 79 +++++++++++++------ .../DramaLing.Api/Data/DramaLingDbContext.cs | 2 +- .../DramaLing.Api/Models/DTOs/FlashcardDto.cs | 10 +++ .../Models/Entities/Flashcard.cs | 1 + 4 files changed, 69 insertions(+), 23 deletions(-) diff --git a/backend/DramaLing.Api/Controllers/FlashcardsController.cs b/backend/DramaLing.Api/Controllers/FlashcardsController.cs index 8c97fed..b43375a 100644 --- a/backend/DramaLing.Api/Controllers/FlashcardsController.cs +++ b/backend/DramaLing.Api/Controllers/FlashcardsController.cs @@ -3,6 +3,7 @@ using Microsoft.EntityFrameworkCore;
