Laravel Decorator

Installation

You can install the package via composer:

composer require mindtwo/laravel-decorator

How to use?

Preparing the Eloquent Model

To use a decorator the underlaying eloquent model must implement the Decoratable interface. Farther you should use the HasDecorator trait, which implements the required methods.

use Illuminate\Database\Eloquent\Model;
use mindtwo\LaravelDecorator\Interfaces\Decoratable;
use mindtwo\LaravelDecorator\Traits\HasDecorator;

class MyModel extends Model implements Decoratable
{
    use HasDecorator;
}

You can optionally setup a default decorator on the eloquent model, which will be used when you call the decorate() method without any params.

use Illuminate\Database\Eloquent\Model;
use mindtwo\LaravelDecorator\Interfaces\Decoratable;
use mindtwo\LaravelDecorator\Traits\HasDecorator;

class MyModel extends Model implements Decoratable
{
    use HasDecorator;

    /**
     * Return the default decorator full qualified class name.
     *
     * @return string
     */
    public function defaultDecorator(): string
    {
        return MyDecorator::class;
    }
}

Writing a Decorator

To write a decorator simply extend the basic decorator class. You can access the undelaying eloquent model by the $this->model property. Whenever you try to access a property on the decorator, it will first look for a function with the camilzed property name. If it is defined, it will be called, otherwise it will be forwarded to the underlaying eloquent model.

use mindtwo\LaravelDecorator\Decorator;

class MyDecorator extends Decorator
{
    /**
     * Get formatted creation date.
     *
     * @return string
     */
    public function defaultDecorator(): string
    {
        return $this->model->created_at->format('Y-m-d');
    }
}

Using a Decorator

To use a decorator simply call the decorate() method on the model. You can use the full qualified class name of a decorator class as parameter to specify a decorator, otherwise the default decorator will be used.

$myObject = MyModel::make();

// Use a certain decorator
$myDecoratedObject = $myObject->decorate(MyDecorator::class);

// Use the default decorator (needs to be defined on the model)
$myDecoratedObject = $myObject->decorate();

It is also possible to call the 'decorate()' method on collections, cause the package autmatically registers it as a macro.

$myCollection = MyModel::get();

// Use a certain decorator
$myDecoratedCollection = $myCollection->decorate(MyDecorator::class);

// Use the default decorator (needs to be defined on the model)
$myDecoratedCollection = $myCollection->decorate();

Note that all items in the collection must implement the Decoratable interface, otherwise this will throw an exception.
