Installation

You can install the package via composer:

composer require coderflexx/laravel-presenter

You can publish the config file with:

php artisan vendor:publish --provider="Coderflex\LaravelPresenter\LaravelPresenterServiceProvider"

This is the contents of the published config file:

return [

    /*
    |--------------------------------------------------------------------------
    | Presenter Namespace
    |--------------------------------------------------------------------------
    |
    | This value informs LaravelPresenter which namespace you will be 
    | selecting to store your presenters by default.
    | If this value equals to null, "App\Presenter" will be used 
    | by default.
    |
    */

    'presenter_namespace'   => 'App\\Presenters',
];

Usage

The implementation of this package is so simple, all what you need to do is the following:

Model Implementation

• Implement CanPresent Interface
• Use UsesPresenters Trait

use Coderflex\LaravelPresenter\Concerns\CanPresent;
use Coderflex\LaravelPresenter\Concerns\UsesPresenters;
// ...

class User extends Authenticatable implements CanPresent
{
    use UsesPresenters;

    // ...
}

Create New Model Presenter class

This package gives you an easy way to generate new Presenter class, all you need to do is to use presenter:make command.

php artisan presenter:make UserPresenter

UserPresenter in our case, leaves by default in App\Presenters.

This is the contents of the UserPresenter file:

<?php

namespace App\Presenters;

use Coderflex\LaravelPresenter\Presenter;

class UserPresenter extends Presenter
{
    // 
}

If you want to change the directory, you have two options.

First options is to set the full namespace while you're creating the presenter class

php artisna presenter:make App\Models\Presenter\UserPresenter

Or change presenter_namespace from config/laravel-presenter file.

return [
    ...

    'presenter_namespace'   => 'App\\Presenters',

    ...
];

Using the Presenter Generated Class

After you create the presenter class, you need to register it on the Model by adding the $presenters protected property:

use App\Presenters\UserPresenter;
use Coderflex\LaravelPresenter\Concerns\CanPresent;
use Coderflex\LaravelPresenter\Concerns\UsesPresenters;
// ...

class User extends Authenticatable implements CanPresent
{
    use UsesPresenters;

    protected $presenters = [
        'default' => UserPresenter,
    ];
}

By default, the type of your presenter class is default, but you can use as many of presenters you want, just by identifying the type in $presenters property.

Example

Now, after we generated the presenter class, and we implemented it successfully in our model, we can use it like so:

In your UserPresenter class or any presenter class you generated.

...
class UserPresenter extends Presenter
{
    public function fullName()
    {
        return "{$this->model->first_name} {$this->model->last_name}";
    }
}
...

We add a new method to present the fullName.

In your blade or any place you want, you can do:

$user->present()->fullName

Your application will show the full name from the method you added.

Adding Another Presenter Type

Like I said above, by default the type will be default but, you can add more types as you need.

Here is an example:

use App\Presenters\UserPresenter;
use Coderflex\LaravelPresenter\Concerns\CanPresent;
use Coderflex\LaravelPresenter\Concerns\UsesPresenters;
// ...

class User extends Authenticatable implements CanPresent
{
    use UsesPresenters;

    protected $presenters = [
        'default' => UserPresenter,
        'setting' => UserSettingPresenter,
    ];
}

Generate new UserSettingPresenter

php artisan presenter:make UserSettingPresenter

Add anything to UserSettingPresenter method

...
class UserSettingPresenter extends Presenter
{
    public function lang()
    {
        return $this->model->settings->defaultLang;
    }
}
...

Finally, set setting as a type:

$user->present('setting')->lang;

By that, you can split your logic and make your code base even cleaner.
