From 939efd70d412c0f119dd9d3185765b39a7b9af61 Mon Sep 17 00:00:00 2001 From: imeepos Date: Mon, 14 Jul 2025 21:34:07 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20=E5=AE=8C=E5=96=84=E6=A8=A1=E6=9D=BF?= =?UTF-8?q?=E5=AF=BC=E5=85=A5=E5=8A=9F=E8=83=BD?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 新增功能: - 添加详细的模板导入日志系统 - 实现全局进度存储机制 - 完善模板状态管理 修复问题: - 修复进度监控无限轮询问题 - 修复模板列表状态显示不正确问题 - 修复所有unwrap()导致的panic错误 - 修复外键约束失败问题 改进: - 优化素材上传逻辑，只上传视频/音频/图片 - 上传失败时自动跳过而不是中断导入 - 缺失文件时继续导入而不是失败 - 改进错误处理机制 --- Cargo.lock | 2 +-
