# Story 4.1: Timeline Creation
## Epic Reference
**Epic 4:** Case Timeline System
## User Story
As an **admin**,
I want **to create case timelines for clients**,
So that **I can track and communicate progress on their legal matters**.
## Story Context
### Existing System Integration
- **Integrates with:** timelines table, timeline_updates table, users table, admin_logs table
- **Technology:** Livewire Volt, Flux UI
- **Follows pattern:** Admin CRUD pattern (see existing admin components)
- **Touch points:** User relationship, client dashboard, audit logging
### Reference Documents
- **Epic:** `docs/epics/epic-4-case-timeline.md`
- **Database Schema:** `docs/stories/story-1.1-project-setup-database-schema.md#database-schema-reference`
- **User Model:** Requires users with `user_type` of 'individual' or 'company' (from Epic 2)
## Acceptance Criteria
### Timeline Creation Form
- [ ] Select client (search by name/email) - only users with user_type 'individual' or 'company'
- [ ] Case name/title (required)
- [ ] Case reference number (optional, unique if provided)
- [ ] Initial notes (optional)
### Behavior
- [ ] Timeline assigned to selected client
- [ ] Creation date automatically recorded
- [ ] Status defaults to 'active'
- [ ] Can create multiple timelines per client
- [ ] Confirmation message on successful creation
- [ ] Timeline immediately visible to client
### Validation
- [ ] Case name required
- [ ] Case reference unique if provided
- [ ] Client must exist
### Quality Requirements
- [ ] Audit log entry created via AdminLog model
- [ ] Bilingual labels and messages
- [ ] Tests for creation flow
## Technical Notes
### File Structure
```
Routes:
GET /admin/timelines/create -> admin.timelines.create
POST handled by Livewire component
Files to Create:
resources/views/livewire/pages/admin/timelines/create.blade.php (Volt component)
Models Required (from Story 1.1):
app/Models/Timeline.php
app/Models/TimelineUpdate.php
app/Models/AdminLog.php
```
### Database Schema
```php
// timelines table (from Story 1.1)
Schema::create('timelines', function (Blueprint $table) {
$table->id();
$table->foreignId('user_id')->constrained()->cascadeOnDelete();
$table->string('case_name');
$table->string('case_reference')->nullable()->unique();
$table->enum('status', ['active', 'archived'])->default('active');
$table->timestamps();
});
// timeline_updates table (from Story 1.1)
Schema::create('timeline_updates', function (Blueprint $table) {
$table->id();
$table->foreignId('timeline_id')->constrained()->cascadeOnDelete();
$table->foreignId('admin_id')->constrained('users')->cascadeOnDelete();
$table->text('update_text');
$table->timestamps();
});
```
### Required Translation Keys
```php
// resources/lang/en/messages.php
'timeline_created' => 'Timeline created successfully.',
// resources/lang/ar/messages.php
'timeline_created' => 'تم إنشاء الجدول الزمني بنجاح.',
// resources/lang/en/labels.php
'case_name' => 'Case Name',
'case_reference' => 'Case Reference',
'initial_notes' => 'Initial Notes',
'select_client' => 'Select Client',
'search_client' => 'Search by name or email...',
'create_timeline' => 'Create Timeline',
// resources/lang/ar/labels.php
'case_name' => 'اسم القضية',
'case_reference' => 'رقم مرجع القضية',
'initial_notes' => 'ملاحظات أولية',
'select_client' => 'اختر العميل',
'search_client' => 'البحث بالاسم أو البريد الإلكتروني...',
'create_timeline' => 'إنشاء جدول زمني',
```
### Volt Component
```php
<?php
use App\Models\AdminLog;
use App\Models\Timeline;
use App\Models\User;
use Livewire\Volt\Component;
new class extends Component {
public string $search = '';
public ?int $selectedUserId = null;
public ?User $selectedUser = null;
public string $caseName = '';
public string $caseReference = '';
public string $initialNotes = '';
public function updatedSearch(): void
{
// Reset selection when search changes
if ($this->selectedUser && ! str_contains(strtolower($this->selectedUser->name), strtolower($this->search))) {
$this->selectedUserId = null;
$this->selectedUser = null;
}
}
public function getClientsProperty()
{
if (strlen($this->search) < 2) {
return collect();
}
return User::query()
->whereIn('user_type', ['individual', 'company'])
->where('status', 'active')
->where(function ($query) {
$query->where('name', 'like', "%{$this->search}%")
->orWhere('email', 'like', "%{$this->search}%");
})
->limit(10)
->get();
}
public function selectUser(int $userId): void
{
$this->selectedUserId = $userId;
$this->selectedUser = User::find($userId);
$this->search = $this->selectedUser->name;
}
public function create(): void
{
$this->validate([
'selectedUserId' => ['required', 'exists:users,id'],
'caseName' => ['required', 'string', 'max:255'],
'caseReference' => ['nullable', 'string', 'max:50', 'unique:timelines,case_reference'],
]);
$timeline = Timeline::create([
'user_id' => $this->selectedUserId,
'case_name' => $this->caseName,
'case_reference' => $this->caseReference ?: null,
'status' => 'active',
]);
// Add initial notes as first update if provided
if ($this->initialNotes) {
$timeline->updates()->create([
'admin_id' => auth()->id(),
'update_text' => $this->initialNotes,
]);
}
AdminLog::create([
'admin_id' => auth()->id(),
'action_type' => 'create',
'target_type' => 'timeline',
'target_id' => $timeline->id,
'new_values' => $timeline->toArray(),
'ip_address' => request()->ip(),
]);
session()->flash('success', __('messages.timeline_created'));
$this->redirect(route('admin.timelines.show', $timeline));
}
}; ?>
<div>
{{-- Component template here using Flux UI --}}
</div>
```
## Test Scenarios
All tests should use Pest and be placed in `tests/Feature/Admin/TimelineCreationTest.php`.
### Happy Path Tests
- [ ] `test_admin_can_view_timeline_creation_form` - Admin can access /admin/timelines/create
- [ ] `test_admin_can_search_clients_by_name` - Search returns matching users
- [ ] `test_admin_can_search_clients_by_email` - Search returns matching users
- [ ] `test_admin_can_create_timeline_with_required_fields` - Timeline created with case_name only
- [ ] `test_admin_can_create_timeline_with_case_reference` - Timeline created with optional reference
- [ ] `test_initial_notes_creates_first_timeline_update` - TimelineUpdate record created
- [ ] `test_audit_log_created_on_timeline_creation` - AdminLog entry exists
### Validation Tests
- [ ] `test_case_name_is_required` - Validation error without case_name
- [ ] `test_case_reference_must_be_unique` - Validation error on duplicate reference
- [ ] `test_case_reference_allows_multiple_nulls` - Multiple timelines without reference allowed
- [ ] `test_client_selection_is_required` - Validation error without selecting client
- [ ] `test_selected_client_must_exist` - Validation error for non-existent user_id
### Authorization Tests
- [ ] `test_non_admin_cannot_access_timeline_creation` - Redirect or 403 for non-admin users
- [ ] `test_guest_cannot_access_timeline_creation` - Redirect to login
### Edge Case Tests
- [ ] `test_search_only_returns_individual_and_company_users` - Admin users not in results
- [ ] `test_search_only_returns_active_users` - Deactivated users not in results
- [ ] `test_can_create_multiple_timelines_for_same_client` - No unique constraint on user_id
## Definition of Done

- [ ] Route registered for admin timeline creation
- [ ] Can search and select client (individual/company only)
- [ ] Can enter case name and reference
- [ ] Timeline created with correct data
- [ ] Initial notes saved as first update
- [ ] Unique reference validation works
- [ ] Client can view timeline immediately (verified via client dashboard)
- [ ] Audit log created
- [ ] All translation keys added (AR/EN)
- [ ] All tests pass
- [ ] Code formatted with Pint
## Dependencies
- **Story 1.1:** Database schema (timelines, timeline_updates, admin_logs tables and models)
- **Story 1.2:** Authentication & role system (admin role check)
- **Story 2.1/2.2:** User accounts exist to assign timelines to
## Estimation
**Complexity:** Low-Medium
