From 2d3c44d5e921befb04f05af887d5cfc6ef5dbf0b Mon Sep 17 00:00:00 2001 From: imeepos Date: Thu, 7 Aug 2025 16:14:18 +0800 Subject: [PATCH] =?UTF-8?q?fix:=20=E4=BF=AE=E5=A4=8D=E5=B7=A5=E4=BD=9C?= =?UTF-8?q?=E6=B5=81=E6=A8=A1=E6=9D=BFJSON=E8=A7=A3=E6=9E=90=E9=94=99?= =?UTF-8?q?=E8=AF=AF?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 添加 WorkflowType 的 From 实现，支持从字符串转换 - 修复 workflow_template_repository 中的JSON字段解析，处理空字符串情况 - 为所有JSON字段（comfyui_workflow_json, ui_config_json, execution_config_json等）添加空字符串检查 - 添加详细的数据库调试测试，帮助诊断JSON解析问题 - 修复 WorkflowTemplateFilter 添加缺失的 search_term 字段 主要修复： 1. JSON解析：当JSON字段为空字符串时，返回空对象而不是解析错误 2. 类型转换：WorkflowType 现在可以从数据库字符串直接转换 3. 错误处理：改进了JSON解析的错误处理逻辑 4. 测试工具：添加了详细的数据库内容检查和逐字段解析测试 这些修复解决了前端 WorkflowList.tsx 中的 'premature end of input' JSON解析错误。 --- .../workflow_template_repository.rs | 55 ++++-- .../src-tauri/src/tests/basic_tests.rs | 170 +++++++++++++++++- 2 files changed, 208 insertions(+), 17 deletions(-) diff --git a/apps/desktop/src-tauri/src/data/repositories/workflow_template_repository.rs b/apps/desktop/src-tauri/src/data/repositories/workflow_template_repository.rs index cfd746d..2432e79 100644 --- a/apps/desktop/src-tauri/src/data/repositories/workflow_template_repository.rs +++ b/apps/desktop/src-tauri/src/data/repositories/workflow_template_repository.rs @@ -474,42 +474,65 @@ impl WorkflowTemplateRepository { // 解析工作流类型 let type_str: String = row.get("type")?;
