-- =============================================================================
-- 逆向物流动作权限码（拒绝搭便车）
--
-- 背景
--   退回接口已拆出专用码 outbound_return（见 add_outbound_return_perm.sql）。
--   余下三个逆向动作此前仍在复用 inventory_stocktake:operation（盲盘作业），
--   职责错配、审计不合规，此处一并收口：
--
--     code                  名称            宿主菜单          用途
--     --------------------  --------------  ----------------  ------------------
--     defective_restock     不良品回库      defective_goods   修好后加回原库存
--     defective_scrap       不良品报废      defective_goods   确认无法维修后销毁
--     stock_change_status   库存状态变更    inventory_mgmt    冻结 / 标不良 / 恢复
--
--   ★ 三者均为**无冒号**形式，刻意的。原因见 add_outbound_return_perm.sql：
--     形如 <menu>:<action> 的权限码会命中 _expand_operation_perms() 的
--     前缀桥接 —— 例如 inventory_stocktake 下已有 inventory_stocktake:operation，
--     若改用 inventory_stocktake:restock，则所有持有盘点操作权的角色会被自动
--     放行，授权面失控。无冒号码不触发桥接，与前端 hasPermission 的精确匹配一致。
--
--   ★ 顺带补建 defective_goods 菜单：二期只加了前端路由（侧边栏由路由驱动，
--     页面本就能访问），但 sys_menu 中没有对应行，导致该页面在权限管理界面
--     不可见、其下权限也无法授予。sys_element.menu_code 有指向 sys_menu(code)
--     的外键，故必须先把菜单建出来。
--
-- 默认授予：SUPER_ADMIN（超管）、SUPERVISOR（主管）、WAREHOUSE_MGR（库管）
--   company_name 置 NULL = 全局模板权限，对所有公司生效（与既有授权一致）。
--   ★ 刻意**不含** OUTBOUND：业务确认出库员只负责正向拣货发货，
--     不参与任何逆向物流操作。
--
-- 幂等：全部带存在性判断，可重复执行。
-- 执行：docker exec -i inventory_db psql -U test -d inventory_system < 本文件

BEGIN;

-- ---------------------------------------------------------------------------
-- 1) 补建「不良品在管台账」菜单（挂在 入库管理 inventory_mgmt 下）
-- ---------------------------------------------------------------------------
INSERT INTO sys_menu (parent_id, name, code, path, sort_order, is_visible)
SELECT (SELECT id FROM sys_menu WHERE code = 'inventory_mgmt'),
       '不良品在管台账', 'defective_goods', '/inventory/defective', 6, TRUE
WHERE NOT EXISTS (SELECT 1 FROM sys_menu WHERE code = 'defective_goods');

-- ---------------------------------------------------------------------------
-- 2) 注册三个权限元素
-- ---------------------------------------------------------------------------
INSERT INTO sys_element (menu_code, name, code, element_type)
SELECT v.menu_code, v.name, v.code, 'operation'
FROM (VALUES
    ('defective_goods', '不良品回库',     'defective_restock'),
    ('defective_goods', '不良品报废',     'defective_scrap'),
    ('inventory_mgmt',  '库存状态变更',   'stock_change_status')
) AS v(menu_code, name, code)
WHERE NOT EXISTS (SELECT 1 FROM sys_element e WHERE e.code = v.code);

-- ---------------------------------------------------------------------------
-- 3) 默认授予三个角色（菜单 + 元素）
-- ---------------------------------------------------------------------------
-- 3.1 菜单
INSERT INTO sys_role_permission (role_code, target_code, type, company_name)
SELECT v.role_code, 'defective_goods', 'menu', NULL
FROM (VALUES ('SUPER_ADMIN'), ('SUPERVISOR'), ('WAREHOUSE_MGR')) AS v(role_code)
WHERE NOT EXISTS (
    SELECT 1 FROM sys_role_permission r
    WHERE r.role_code = v.role_code AND r.target_code = 'defective_goods'
      AND r.type = 'menu'
);

-- 3.2 元素
INSERT INTO sys_role_permission (role_code, target_code, type, company_name)
SELECT r.role_code, v.target_code, 'element', NULL
FROM (VALUES ('SUPER_ADMIN'), ('SUPERVISOR'), ('WAREHOUSE_MGR')) AS r(role_code)
CROSS JOIN (VALUES
    ('defective_restock'), ('defective_scrap'), ('stock_change_status')
) AS v(target_code)
WHERE NOT EXISTS (
    SELECT 1 FROM sys_role_permission x
    WHERE x.role_code = r.role_code AND x.target_code = v.target_code
      AND x.type = 'element'
);

-- ---------------------------------------------------------------------------
-- 4) 执行后核对
-- ---------------------------------------------------------------------------
\echo '--- 菜单已建立 ---'
SELECT code, name, path FROM sys_menu WHERE code = 'defective_goods';

\echo '--- 三个权限元素（应 3 行）---'
SELECT e.code, e.name, e.menu_code, e.element_type

 GROUP BY target_code, type ORDER BY type, target_code;

\echo '--- 确认 OUTBOUND 未获得任何逆向权限（应为 0 行）---'
SELECT target_code FROM sys_role_permission
 WHERE role_code = 'OUTBOUND'
   AND target_code IN ('outbound_return', 'defective_goods', 'defective_restock',
                       'defective_scrap', 'stock_change_status');
