"""tasks.deleted_at 列(任务软删除).
|
|
|
|
Revision ID: 0010
|
|
Revises: 0009
|
|
Create Date: 2026-06-17
|
|
|
|
给 tasks 加 deleted_at 列(可空,默认 NULL=未删)。DELETE /v1/tasks/{id} 从硬删
|
|
改为软删(置 deleted_at=now()),列表查询过滤 deleted_at IS NULL;新增
|
|
POST /v1/tasks/{id}/restore 恢复。软删后 messages / usage_events(原 CASCADE 不再触发)
|
|
及工作目录文件全部保留,留作训练语料并支持恢复。
|
|
|
|
只加列、不动现有数据;历史行 deleted_at 默认 NULL,自动视为"未删"。
