To get the latest version, simply require the project using Composer:
$ composer require mccool/laravel-auto-presenter
Once installed, if you are not using automatic package discovery, then you need to register the McCool\LaravelAutoPresenter\AutoPresenterServiceProvider service provider in your config/app.php.
You can also optionally alias our facade:
'AutoPresenter' => McCool\LaravelAutoPresenter\Facades\AutoPresenter::class,
Upgrading
Version 6 to 7
In Laravel Auto Presenter 7, note that:
- Laravel 5.5-8 are supported now. Use V6 if you need L5.1-5.4.
- Our new minimum PHP version requirement is 7.1.3, up from 7.0.0.
Version 5 to 6
Going from Laravel Auto Presenter 5, to 6, note that:
- We have a new
Decoratableinterface to determine if relations can be decorated. While this is not a BC break, sinceHasPresenterextends it, it is definitely worth noting. - v6 supports Laravel 5.5 now, without dropping support for 5.1+.
- Our new minimum PHP version requirement is 7.0.0, up from 5.5.9.
Version 4 to 5
If you're upgrading from Laravel Auto Presenter 4, to 5, note that:
- The
BasePresenterno longer has a constructor, so you cannot callparent::__construct($resource). - The model is now injected using the
setWrappedObjectmethod, inherited from theBasePresenter. - V5 now supports Laravel 5.4 as well as 5.1, 5.2, and 5.3.
Usage
To show how it's used, we'll pretend that we have an Eloquent Post model. It doesn't have to be Eloquent, it could be any kind of class. But, this is a normal situation. The Post model represents a blog post.
I'm using really basic code examples here, so just focus on how the auto-presenter is used and ignore the rest.
use Example\Accounts\User;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
protected $table = 'posts';
protected $fillable = ['author_id', 'title', 'content', 'published_at'];
public function author()
{
return $this->belongsTo(User::class, 'author_id');
}
}
Also, we'll need a controller..
use Example\Accounts\Post;
use Illuminate\Routing\Controller;
use Illuminate\Support\Facades\View;
class PostsController extends Controller
{
public function getIndex()
{
$posts = Post::all();
return View::make('posts.index', compact('posts'));
}
}
and a view...
@foreach($posts as $post)
<li>{{ $post->title }} - {{ $post->published_at }}</li>
@endforeach
In this example the published_at attribute is likely to be in the format: "Y-m-d H:i:s" or "2013-08-10 10:20:13". In the real world this is not what we want in our view. So, let's make a presenter that lets us change how the data from the Post class is rendered within the view.
use Carbon\Carbon;
use Example\Accounts\Post;
use McCool\LaravelAutoPresenter\BasePresenter;
class PostPresenter extends BasePresenter
{
public function published_at()
{
$published = $this->wrappedObject->published_at;
return Carbon::createFromFormat('Y-m-d H:i:s', $published)
->toFormattedDateString();
}
}
Note that the model is injected by calling the setWrappedObject method, inherited from BasePresenter.
We need the post class to implement the interface.
use Example\Accounts\User;
use Example\Blog\PostPresenter;
use McCool\LaravelAutoPresenter\HasPresenter;
use Illuminate\Database\Eloquent\Model;
class Post extends Model implements HasPresenter
{
protected $table = 'posts';
protected $fillable = ['author_id', 'title', 'content', 'published_at'];
public function author()
{
return $this->belongsTo(User::class, 'author_id');
}
public function getPresenterClass()
{
return PostPresenter::class;
}
}
Now, with no additional changes our view will show the date in the desired format.
The Decoratable interface is used to allow the model's relations to be decorated, and the HasPresenter interface (which extends that one) is used to have the model itself decorated.
Troubleshooting
If an object isn't being decorated correctly in the view then there's a good chance that it's simply not in existence when the view begins to render. For example, lazily-loaded relationships won't be decorated. You can fix this by eager-loading them instead. Auth::user() will never be decorated. I prefer to bind $currentUser to my views, anyway.
If an object is a relation of another object and it isn't being decorated in the view, you might not have added the Decoratable interface to the other object. To fix this, add the Decoratable interface to the other object.
