# Story 4.2: Timeline Updates Management
|
|
|
|
## Epic Reference
|
|
**Epic 4:** Case Timeline System
|
|
|
|
## User Story
|
|
As an **admin**,
|
|
I want **to add and edit updates within a timeline**,
|
|
So that **I can keep clients informed about their case progress**.
|
|
|
|
## Story Context
|
|
|
|
### Existing System Integration
|
|
- **Integrates with:** timeline_updates table, timelines table
|
|
- **Technology:** Livewire Volt, rich text editor (Trix recommended)
|
|
- **Follows pattern:** Nested CRUD pattern
|
|
- **Touch points:** Client notifications, timeline view
|
|
|
|
### Previous Story Context (Story 4.1)
|
|
Story 4.1 established:
|
|
- `Timeline` model with fields: `user_id`, `case_name`, `case_reference`, `status`
|
|
- `updates()` hasMany relationship on Timeline model
|
|
- `timelines` table with foreign key to users
|
|
- Admin can create timelines for any client
|
|
- Initial notes saved as first timeline update
|
|
|
|
### Prerequisites
|
|
- `Timeline` model with `updates()` relationship (from Story 4.1)
|
|
- `TimelineUpdate` model (create in this story)
|
|
- `AdminLog` model for audit logging (from Epic 1)
|
|
- HTML sanitization: use `mews/purifier` package with `clean()` helper
|
|
- Rich text editor: Trix (ships with Laravel) or similar
|
|
|
|
### Implementation Files
|
|
- **Volt Component:** `resources/views/livewire/pages/admin/timelines/updates.blade.php`
|
|
- **Model:** `app/Models/TimelineUpdate.php`
|
|
- **Notification:** `app/Notifications/TimelineUpdateNotification.php`
|
|
- **Route:** `admin.timelines.show` (timeline detail page with updates section)
|
|
|
|

```php
|
|
Schema::create('timeline_updates', function (Blueprint $table) {
|
|
$table->id();
|
|
$table->foreignId('timeline_id')->constrained()->cascadeOnDelete();
|
|
$table->foreignId('admin_id')->constrained('users');
|
|
$table->text('update_text');
|
|
$table->timestamps();
|
|
});
|
|
```
|
|
|
|
### TimelineUpdate Model
|
|
```php
|
|
// app/Models/TimelineUpdate.php
|
|
class TimelineUpdate extends Model
|
|
{
|
|
protected $fillable = ['timeline_id', 'admin_id', 'update_text'];
|
|
|
|
public function timeline(): BelongsTo
|
|
{
|
|
return $this->belongsTo(Timeline::class);
|
|
}
|
|
|
|
public function admin(): BelongsTo
|
|
{
|
|
return $this->belongsTo(User::class, 'admin_id');
|
|
}
|
|
}
|
|
```
|
|
|
|
### Timeline Model Relationship (add to existing model)
|
|
```php
|
|
// In app/Models/Timeline.php - add this relationship
|
|
public function updates(): HasMany
|
|
{
|

return $this->hasMany(TimelineUpdate::class)->orderBy('created_at', 'asc');
|
|
}
|
|
```
|
|
|
|
### Setup Requirements
|
|
```bash
|
|
# Install HTML Purifier for sanitization
|
|
composer require mews/purifier
|
|

## Dependencies
|
|
|
|
- **Story 4.1:** Timeline creation (REQUIRED - must be complete)
|
|

|
|
- If Epic 8 is not complete, implement notification dispatch but skip email tests
|
|
- Create `TimelineUpdateNotification` class with queued email
|
|
- Notification will work once Epic 8 email infrastructure is ready
|
|
|
|
## Estimation
|
|
|
|
**Complexity:** Medium
|
|
**Estimated Effort:** 3-4 hours

### Change Log
|

|
|
2. Updated Timeline model to order updates chronologically (oldest first)
|
|
3. Created TimelineUpdateNotification class with queued email support
|
|
4. Created bilingual email template for timeline update notifications
|
|
5. Created Volt component for timeline show page with:
|
|
- Timeline header (case name, reference, status, client info)
|
|
- Add update form with validation (min 10 chars)
|
|
- Visual timeline with chronological updates display
|
|
- Edit update functionality
|
|
- Audit logging for add/edit operations

|
|
|
|
### Completion Notes
|
|
- Component path is `admin/timelines/show.blade.php` (matching existing structure)
|
|
- Rich text formatting is supported via HTML Purifier which allows safe tags (strong, em, a, ul, ol, li)
|
|
- AdminLog uses `action` field (not `action_type` as in story spec) to match existing model
|
|
- Timeline creation now redirects to the show page instead of dashboard
|
|
- Visual timeline uses a vertical line design with circular nodes for updates
|
