"""一键导入模板：文件夹内图片文件名 = 菜名。
|
||
|
||
用法（在项目根目录）::
|
||
|
||
python tools/import_templates_by_name.py "D:\\菜品模板"
|
||
python tools/import_templates_by_name.py "D:\\菜品模板" --dry-run
|
||
python tools/import_templates_by_name.py "D:\\菜品模板" --local-only
|
||
|
||
说明:
|
||
- 旧版逐张 add_template 时，每张都会从 MySQL 全量/增量同步，容易把本地刚写入的冲掉
|
||
- 本脚本改为批量写入，最后只同步一次
|
||
- --local-only：只写本机 SQLite（并入上传队列），不立刻连 MySQL 拉取
