Laravel Activity Presenter

Laravel Activity Presenter is a powerful presentation layer for spatie/laravel-activitylog. It solves the common challenges of displaying activity logs in your application: resolving relationships efficiently, formatting data consistently, and handling translations.

Why use this?

When displaying activity logs, you often face these issues:

1. N+1 Queries: Showing "User X updated Project Y" requires loading the User and Project models for every log entry.
2. Missing Context: If "Project Y" is deleted, you still want to show its name in the log history, but the relationship is null.
3. Unformatted Data: You have user_id: 5 in the log properties, but you want to display "John Doe".
4. Inconsistent Presentation: You find yourself repeating trans('...')... logic in every Blade view.

This package solves all of them.

Key Features

• Smart Resolution: Automatically resolves related models (User, Subject) in a single optimized query to prevent N+1 issues.
• Object-Oriented: Provides rich objects (LogEntry, AttributeChange) instead of flat strings, giving you full control in your View.
• Config-Driven: Define how specific attributes (like category_id) map to models in a simple config file.
• Auto-Localization: Built-in support for translating events (created -> Creado), model names (User -> Usuario), and attributes.
• Agnostic & Flexible: Does not force date formats or string styles. You get the raw Carbon objects and Models to format however you like.

Installation

Install via Composer (Spatie Activitylog is included automatically):

composer require deifhelt/laravel-activity-presenter

Publish the configuration:

php artisan vendor:publish --provider="Deifhelt\ActivityPresenter\ActivityPresenterServiceProvider"

Quick Usage

1. In your Controller

use Deifhelt\ActivityPresenter\Facades\ActivityPresenter;
use Spatie\Activitylog\Models\Activity;

public function index()
{
    // Fetch logs (paginated)
    $activities = Activity::latest()->paginate(20);

    // Present them (loads relations, formats dates, translates events)
    $presented = ActivityPresenter::presentCollection($activities);

    return view('activities.index', [
        'activities' => $presented
    ]);
}

2. In your Blade View

@foreach($activities as $log)
    <div class="activity-item">
        <!-- Full Control over Date Format -->
        <span class="date">{{ $log->activity->created_at->diffForHumans() }}</span>

        <!-- "John Doe created Project Alpha" -->
        <p>
            @if($log->causer)
                <a href="{{ route('users.show', $log->causer) }}">
                    <strong>{{ $log->getCauserLabel() }}</strong>
                </a>
            @else
                System
            @endif

            {{ $log->getEventLabel() }}

            <strong>{{ $log->getSubjectLabel() }}</strong>
        </p>

        <!-- Show changes: "Status: Pending -> Active" -->
        <ul>
            @foreach($log->changes as $change)
                <li>
                     {{ $change->key }}:

                     <span class="text-red-500">{{ $change->old }}</span>
                     &rarr;

                     <!-- If it's a resolved model (e.g. status_id -> Status Model), link to it! -->
                     @if($change->relatedModel)
                        <a href="{{ route('statuses.show', $change->relatedModel) }}" class="text-green-500">
                            {{ $change->relatedModel->name }}
                        </a>
                     @else
                        <span class="text-green-500">{{ $change->new }}</span>
                     @endif
                </li>
            @endforeach
        </ul>
    </div>
@endforeach
