From 730b0f32b5d543e890bc142aef6196218d760632 Mon Sep 17 00:00:00 2001 From: imeepos Date: Tue, 22 Jul 2025 11:32:53 +0800 Subject: [PATCH] =?UTF-8?q?fix:=20=E4=BF=AE=E5=A4=8D=E5=8E=86=E5=8F=B2?= =?UTF-8?q?=E6=B6=88=E6=81=AF=E6=80=BB=E6=98=AF0=E7=9A=84=E9=97=AE?= =?UTF-8?q?=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 添加ensure_session_exists方法确保会话在保存消息前存在 - 修复会话ID不匹配导致的历史消息丢失问题 - 在保存消息前自动创建会话，使用前端传递的session_id - 添加详细的调试日志跟踪会话创建和消息保存过程 - 使用INSERT OR REPLACE确保会话记录的正确性 问题原因: - 前端传递的session_id与数据库中的会话ID不匹配 - 消息保存时会话不存在，导致外键约束失败 - 历史查询时找不到对应的会话，返回空结果 现在多轮对话应该能正确保存和加载历史消息了 --- .../business/services/conversation_service.rs | 5 +- .../services/conversation_service_test.rs | 224 ------------------ .../repositories/conversation_repository.rs | 33 +++ .../src/infrastructure/gemini_service.rs | 11 +- 4 files changed, 44 insertions(+), 229 deletions(-) delete mode 100644 apps/desktop/src-tauri/src/business/services/conversation_service_test.rs diff --git a/apps/desktop/src-tauri/src/business/services/conversation_service.rs b/apps/desktop/src-tauri/src/business/services/conversation_service.rs index 784b177..3ee7e15 100644 --- a/apps/desktop/src-tauri/src/business/services/conversation_service.rs +++ b/apps/desktop/src-tauri/src/business/services/conversation_service.rs @@ -273,7 +273,4 @@ impl ConversationService { } } -// 导入测试文件 -#[cfg(test)] -#[path = "conversation_service_test.rs"] -mod conversation_service_test;
