From ef4c047b30813126c401e021a68c13d57e325039 Mon Sep 17 00:00:00 2001 From: imeepos Date: Wed, 16 Jul 2025 00:56:51 +0800 Subject: [PATCH] =?UTF-8?q?fix(template-matching):=20=E4=BF=AE=E5=A4=8D?= =?UTF-8?q?=E6=A8=A1=E6=9D=BF=E7=B4=A0=E6=9D=90=E5=8C=B9=E9=85=8D=E9=80=BB?= =?UTF-8?q?=E8=BE=91?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 修复的问题: - 固定素材被错误计入失败统计，导致成功率偏低 - 素材未切分时无可用片段，导致匹配完全失败 - 模板绑定验证逻辑未实现，返回空数据 - 时长单位不一致影响匹配准确性 主要改进: - 固定素材现在正确跳过匹配，不计入失败数 - 实现虚拟片段机制，为未切分素材创建虚拟片段 - 完善模板绑定验证逻辑，正确统计片段数量 - 修正时长单位转换，确保匹配准确性 - 增强错误信息，提供更详细的匹配失败原因 修复效果: - 修复前: 0个可用片段 匹配完全失败 - 修复后: 44个可用片段 匹配正常工作 - 三种匹配规则(固定素材/AI分类/随机匹配)现在都能正常工作 技术细节: - 在匹配前过滤固定素材，避免错误统计 - 为每个分类记录创建对应的虚拟片段 - 成功率基于可匹配片段计算，更准确反映匹配质量 - 实现完整的模板绑定验证，支持匹配预估 --- .../services/material_matching_service.rs | 90 +++++++++++++++---- .../commands/material_matching_commands.rs | 77 ++++++++++++++-- apps/desktop/src/pages/ProjectDetails.tsx | 1 + 3 files changed, 144 insertions(+), 24 deletions(-) diff --git a/apps/desktop/src-tauri/src/business/services/material_matching_service.rs b/apps/desktop/src-tauri/src/business/services/material_matching_service.rs index a203843..20df000 100644 --- a/apps/desktop/src-tauri/src/business/services/material_matching_service.rs +++ b/apps/desktop/src-tauri/src/business/services/material_matching_service.rs @@ -101,7 +101,7 @@ impl MaterialMatchingService { // 获取项目的所有素材 let project_materials = self.material_repo.get_by_project_id(&request.project_id)?;
