Backend Forms:
- Domain/Forms: ContractTemplate (FormCode, Name, ContractType, FileName, StoragePath, Format, FieldSpec JSON, IsActive) + ContractClause
- EF config voi unique FormCode + query filter IsDeleted
- DbSets + IApplicationDbContext update
- Migration AddForms (bang 14 total)
- Packages: DocumentFormat.OpenXml 3.x + ClosedXML 0.105+
- Application/Forms:
- IFormRenderer interface + RenderResult record
- FormFeatures.cs: List/Get/Render CQRS
- IWebHostEnvironmentLocator (abstract IWebHostEnvironment)
- Infrastructure/Forms:
- DocxRenderer: OpenXml-based placeholder {{field}} replace, handle split runs (gom text tat ca <w:t> trong paragraph, replace, gan lai text dau + clear rest)
- XlsxRenderer: ClosedXML cell value replace
- FormRenderer router theo format docx/xlsx
- Api:
- FormsController: GET /templates (filter type, onlyActive), GET /templates/{id}, POST /templates/{id}/render (return file)
- WebHostEnvironmentLocator impl
- DbInitializer SeedContractTemplatesAsync: seed 8 template metadata, IsActive=true chi khi file ton tai
Templates vat ly:
- Copy 5 .docx/.xlsx tu FORM/ sang wwwroot/templates/
- 3 .doc (FO-002.02/03/06) chua convert: IsActive=false (Word COM bi stuck luc test, can retry voi DisplayAlerts=0 hoac LibreOffice)
- scripts/convert-doc-to-docx.ps1 (Word COM automation)
Frontend fe-admin:
- types/forms.ts: ContractTemplate + ContractTypeLabel
- pages/forms/FormsPage.tsx: list templates + Render dialog (paste JSON data → download .docx/.xlsx)
- Route /forms them vao App.tsx
Bug fix:
- SpaceProcessingModeValues namespace: wrap EnumValue<> full path
- SaveAs2($path, 16) thay vi SaveAs([ref], [ref]) — PowerShell type issue
- Word COM stuck: kill process, skip .doc cho MVP
Docs (theo yeu cau user):
- docs/gotchas.md MOI: 17 pitfalls nhom theo tech stack / EF Core / OpenXml / JSON / dev workflow
- .claude/skills/form-engine/SKILL.md: placeholder → full spec (algorithm + code pointers + API + limitations)
- .claude/skills/permission-matrix/SKILL.md: placeholder → full spec (BE policy + FE guard + seed + pitfalls)

E2E verified:
- GET /api/forms/templates (onlyActive=false) → 8 templates
- POST /api/forms/templates/{FO-002.05}/render voi data dict → HTTP 200 + file .docx 482KB (Microsoft Word 2007+ OK)

description: Hệ thống phân quyền Role × MenuKey × CRUD. Seed 12 menu + admin full. FE PermissionGuard + usePermission. BE AuthorizationHandler + 48 policy. Dùng khi debug access denied, gán role, menu không hiện.
|
||
when-to-use:
|
||
- "permission denied"
|
||
- "access denied"
|
||
- "menu không hiện"
|
||
- "gán role cho user"
|
||
- "seed permission"
|

# Permission Matrix Skill
|
||
|
||
> **Status:** Phase 1 đợt 2 IMPLEMENTED.
|
||
|
||
## Model
|
||
|
||
```
|
||
User ────< UserRoles ────< Role ────< Permissions ────< MenuItem
|
||
(RoleId, MenuKey, CRUD flags)
|
||
```
|
||
|
||
- 1 User có N Role (qua `AspNetUserRoles` rename → `UserRoles`)
|
||
- 1 Role có N Permission (1 row per MenuKey × 4 CRUD flag)
|
||
- Union (OR) nhiều role → user có quyền nếu **bất kỳ role nào** cho quyền đó
|
||
- Admin role → **bypass** check (luôn pass mọi policy)
|
||
|
||
## Menu tree (seed)
|
||
|
||
12 menu trong `MenuKeys.All`:
|
||
|
||
```
|
||
Dashboard
|
||
Master
|
||
├── Suppliers
|
||
├── Projects
|
||
└── Departments
|
||
Contracts
|
||
Forms
|
||
Reports
|
||
System
|
||
├── Users
|
||
├── Roles
|
||
└── Permissions
|
||
```
|
||
|
||
Tree hierarchy qua `ParentKey` field. Seed trong `DbInitializer.SeedMenuTreeAsync`.
|
||
|
||
## Code pointers
|
||
|
||
**Backend:**
|
||
- `Domain/Identity/MenuKeys.cs` — const class, single source of truth
|
||
- `Domain/Identity/MenuItem.cs` — entity (Key PK, Label, ParentKey, Order, Icon)
|
||
- `Domain/Identity/Permission.cs` — entity (RoleId, MenuKey, 4 flag)
|
||
- `Application/Permissions/Queries/GetMyMenuTree/GetMyMenuTreeQuery.cs` — resolve per-user, union OR, filter tree
|
||
- `Application/Permissions/PermissionFeatures.cs` — list/upsert
|
||
- `Api/Authorization/MenuPermissionRequirement.cs` + `MenuPermissionHandler.cs` — policy check
|
||
- `Api/Program.cs` — register 48 policy `{menu}.{action}` trong AddAuthorization
|
||
- `Infrastructure/Persistence/DbInitializer.cs` — `SeedMenuTreeAsync` + `SeedAdminPermissionsAsync`
|
||
- `Api/Controllers/MenusController.cs`, `RolesController.cs`, `PermissionsController.cs`
|
||
|
||
**Frontend (fe-admin):**
|
||
- `src/lib/menuKeys.ts` — const mirror, cần **đồng bộ tay** với BE
|
||
- `src/types/menu.ts` — MenuNode type
|
||
- `src/hooks/usePermission.ts` — `can(menuKey, action)` helper
|
||
- `src/components/PermissionGuard.tsx` — wrap button/content
|
||
- `src/components/Layout.tsx` — render sidebar động từ AuthContext.menu
|
||
- `src/pages/system/PermissionsPage.tsx` — ma trận edit UI
|
||
- `src/contexts/AuthContext.tsx` — `loadMenu()` on login + localStorage cache
|
||
|
||
## BE policy usage
|
||
|
||
Register trong Program.cs:
|
||
|
||
```csharp
|
||
services.AddAuthorization(opts =>
|
||
{
|
||
foreach (var menu in MenuKeys.All)
|
||
foreach (var action in MenuKeys.Actions)
|
||
opts.AddPolicy($"{menu}.{action}", p =>
|
||
p.Requirements.Add(new MenuPermissionRequirement(menu, action)));
|
||
});
|
||
services.AddScoped<IAuthorizationHandler, MenuPermissionHandler>();
|
||
```
|
||
|
||
Apply ở controller:
|
||
|
||
```csharp
|
||
[HttpPut("{id:guid}")]
|
||
[Authorize(Policy = "Contracts.Update")]
|
||
public async Task<IActionResult> Update(...) { }
|
||
```
|
||
|
||
## FE guard usage
|
||
|
||
```tsx
|
||
// Hook
|
||
const { can } = usePermission()
|
||
if (!can('Contracts', 'Update')) return null
|
||
|
||
// Component wrap
|
||
<PermissionGuard menuKey="Contracts" action="Update">
|
||
<Button>Sửa</Button>
|
||
</PermissionGuard>
|
||
|
||
// Route guard
|
||
<Route
|
||
path="/system/permissions"
|
||
element={
|
||
<PermissionGuard menuKey="Permissions" action="Read" fallback={<Forbidden />}>
|
||
<PermissionsPage />
|
||
</PermissionGuard>
|
||
}
|
||
/>
|
||
```
|
||
|
||
## Workflow — gán quyền cho role mới
|
||
|
||
1. Admin login → `/system/permissions`
|
||
2. Chọn role (vd "CostControl")
|
||
3. Tick checkbox trên matrix grid — mỗi lần tick tự động PUT `/api/permissions` upsert
|
||
4. User thuộc role đó logout/login lại → thấy permission mới (menu refresh từ `/api/menus/me`)
|
||
|
||
## Guard rules đã implement
|
||
|
||
- **Admin bypass:** role `Admin` luôn pass mọi policy (kể cả chưa seed row Permission)
|
||
- **Not user active:** `User.IsActive=false` → AuthorizationHandler return fail
|
||
- **Self-demote protection:** admin đang edit không thể giảm quyền role Admin (check trong `UpsertPermissionCommandHandler`)
|
||
|
||
## Common pitfalls
|
||
|
||
- **Quên refresh menu sau update permission** → user thấy menu cũ. Giải pháp: logout/login, hoặc Phase 3 thêm SignalR push.
|
||
- **MenuKey typo** — TS không check vì menu.key là string. Luôn dùng `MenuKeys.Contracts` const, không hardcode `"Contracts"`.
|
||
- **FE cache menu trong localStorage** → sau user được assign role mới, FE thấy menu cũ. Login lại fix.
|
||
- **Hai role conflict** (1 cho, 1 cấm): union OR → có ít nhất 1 role cho là được.
|
||
- **403 ở API nhưng FE không hide button** → FE guard chỉ UX, BE phải là source of truth. Phải apply `[Authorize(Policy = "X.Y")]` ở controller.
|
||
|
||
## Phase tiếp theo
|
||
|
||
- **Phase 3:** SignalR notify khi permission đổi → FE tự refetch `/api/menus/me`
|
||
- **Phase 4:** Per-user override (ngoài role) — thêm bảng `UserPermissionOverrides`
|
||
- **Phase 4:** Invalidate JWT khi role đổi (rare event, nhưng secure)
