pqhuy1987 5113e4c771 [CLAUDE] Phase2: Form Engine MVP + docs (gotchas, skill, handoff)
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)
- docs/HANDOFF.md MOI: brief 5 phut cho session sau (run quickstart + where we are + next steps + file tree + gotchas ref)
- docs/STATUS.md: update cumulative stats + next up Phase 3
- docs/changelog/migration-todos.md: tick Phase 2 iteration 1 items + add iteration 2 list
- docs/changelog/sessions/2026-04-21-1200-phase2-form-engine.md: session log
- CLAUDE.md root: them reference den gotchas + HANDOFF

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)

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.csSeedMenuTreeAsync + 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.tscan(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.tsxloadMenu() on login + localStorage cache

BE policy usage

Register trong Program.cs:

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:

[HttpPut("{id:guid}")]
[Authorize(Policy = "Contracts.Update")]
public async Task<IActionResult> Update(...) { }

FE guard usage

// 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)
