README

Package to assist the implementation of the Repository Pattern using Eloquent ORM.

Installation

Installing via Composer

composer require phucnguyenvn/laravel-eloquent-repository

To configure the package options, declare the Service Provider in the config/app.php file.

'providers' => [
    ...
    phucnguyenvn\EloquentRepository\Providers\RepositoryServiceProvider::class,
],

If you are using version 5.5 or higher of Laravel, the Service Provider is automatically recognized by Package Discover.

Usage

To get started you need to create your repository class and extend the EloquentRepository available in the package. You also have to set the Model that will be used to perform the queries.

Example:

namespace App\Repositories;

use App\Models\User;
use phucnguyenvn\EloquentRepository\Repositories\EloquentRepository;

class UserRepository extends EloquentRepository
{
    /**
     * Repository constructor.
     */
    public function __construct(User $user){
        parent::__construct($user);
    }
}

Now it is possible to perform queries in the same way as it is used in Eloquent.

namespace App\Repositories;

use App\Models\User;
use phucnguyenvn\EloquentRepository\Repositories\EloquentRepository;

class UserRepository extends EloquentRepository
{
    /**
     * Repository constructor.
     */
    public function __construct(User $user){
        parent::__construct($user);
    }
    
    public function getAllUser(){
        return $this->all();
    }
    
    public function getByName($name) {
        return $this->where("name", $name)->get();
    }
    
    // You can create methods with partial queries
    public function filterByProfile($profile) {
        return $this->where("profile", $profile);
    }
    
    // Them you can use the partial queries into your repositories
    public function getAdmins() {
        return $this->filterByProfile("admin")->get();
    }
    public function getEditors() {
        return $this->filterByProfile("editor")->get();
    }
    
    // You can also use Eager Loading in queries
    public function getWithPosts() {
        return $this->with("posts")->get();
    }
}

To use the class, just inject them into the controllers.

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Repositories\UserRepository;

class UserController extends Controller
{
    protected function index(UserRepository $repository) {
        return $repository->getAdmins();
    }
}

The injection can also be done in the constructor to use the repository in all methods.

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Repositories\UserRepository;
class UserController extends Controller
{
    private $userRepository;
	public function __construct()(UserRepository $userRepository) {
        $this->userRepository = $userRepository;
    }
    
    public function index() {
        return $this->userRepository->getAllUsers();
    }
    
}

The Eloquent/QueryBuilder methods are encapsulated as protected and are available just into the repository class. Declare your own public data access methods within the repository to access them through the controller.
