Repository Design Pattern for Laravel

Install

To get the latest version of Laravel Exceptions, simply require the project using Composer:

composer require recca0120/repository

Instead, you may of course manually update your require block and run composer update if you so choose:

{
    "require": {
        "recca0120/repository": "~2.0.0"
    }
}

Usage

Eloquent

Create a Model

Create your model normally, but it is important to define the attributes that can be filled from the input form data.

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $fillable = [
        'title',
        'author',
     ];
}

Create a Contract

namespace App\Repositories\Contracts;

interface PostRepository
{

}

Create a Repository

namespace App\Repositories;

use App\Repositories\Contracts\PostRepository as PostRepositoryContract;
use App\Post;
use Recca0120\Repository\EloquentRepository;

class PostRepository extends EloquentRepository implements PostRepositoryContract
{
    public function __construct(Post $model)
    {
        $this->model = $model;
    }
}

Bind

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Repositories\Contracts\PostRepository as PostRepositoryContract;

class AppServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton(PostRepositoryContract::class, PostRepository::class);
    }
}

Controller

namespace App\Http\Controllers;

use App\Repositories\Contracts\PostRepository;

class PostsController extends Controller
{
    protected $repository;

    public function __construct(PostRepository $repository)
    {
        $this->repository = $repository;
    }
}

Methods

Find all results in Repository

$posts = $this->repository->get();

Find all results in Repository with pagination

$posts = $this->repository->paginate();

Count results in Repository

$posts = $this->repository->count();

Create new entry in Repository

$post = $this->repository->create(request()->all());

Update entry in Repository

$post = $this->repository->update($id, request()->all());

Delete entry in Repository

$this->repository->delete($id);

New instance

$post = $this->repository->newInstance([
    'author' => 'author'
]);

Return Model With Conditions

$model = $this->repository->matching(Criteria::create()->where('title', '=', 'title'));

Find result by id

$post = $this->repository->find($id);

Find by conditions

Using the Criteria

Criteria is support all of Eloquent functions

Single Criteria

use Recca0120\Repository\Criteria;

$criteria = Criteria::create()
    ->select('*')
    ->where('author', '=', 'author')
    ->orWhere('title', '=', 'title')
    ->orderBy('author', 'asc');

$this->repository->get($criteria);
$this->repository->paginate($criteria);

Multiple Criteria

use Recca0120\Repository\Criteria;

$criteria = [];

$criteria[] = Criteria::create()
    ->orderBy('author', 'asc');

$criteria[] = Criteria::create()
    ->where('author', '=', 'author')
    ->orWhere('title', '=', 'title');

$this->repository->get($criteria);
// $this->repository->paginate($criteria);

With

use Recca0120\Repository\Criteria;

$criteria = Criteria::create()
    ->with('author', function($criteria) {
        $criteria->where('author', 'author');
    });

$this->repository->get($criteria);
// $this->repository->paginate($criteria);

Join

use Recca0120\Repository\Criteria;

$criteria = Criteria::create()
    ->join('author', function ($criteria) {
        $criteria->on('posts.author_id', '=', 'author.id');
    });

$this->repository->get($criteria);
// $this->repository->paginate($criteria);

Expression

use Recca0120\Repository\Criteria;

$criteria = Criteria::create()
    ->where('created_at', '<=', Criteria::expr('NOW()'));

$this->repository->get($criteria);
// $this->repository->paginate($criteria);

Custom Criteria

use Recca0120\Repository\Criteria;

class CustomCriteria extends Criteria
{
    public function __construct($id)
    {
        $this->where('id', '=', $id);
    }
}

$this->repository->get((new CustomCriteria(1))->where('autor', 'autor'));
