Generic Repository Pattern implementation with laravel

Create a database in mysql

drop table test;
create table test(
id int(11) AUTO_INCREMENT PRIMARY KEY,
name text
);

drop table test;

create table test(

id int(11) AUTO_INCREMENT PRIMARY KEY,

name text

);

or create model by artisan command

php artisan make:model Test

1	php artisan make:model Test

or create model in folder

php artisan make:model Models\\Test

1	php artisan make:model Models\\Test

It will create Models folder and put Test in Models folder

Create a folder Repositories in app directory .

in repository

BaseInterface.php

namespace App\Repositories;

interface BaseInterface{
    public function all();
   // public function paginate($count);
    public function find($id,$relation=[]);
   /* public function findBy($field,$value);
    public function store($data);
    public function update($data);
    public function delete($id);*/

}

namespace App\Repositories;

interface BaseInterface{

public function all();

// public function paginate($count);

public function find($id,$relation=[]);

/* public function findBy($field,$value);

public function store($data);

public function update($data);

public function delete($id);*/

}

BaseRepository.php

namespace App\Repositories;

use App\Repositories\BaseInterface;

abstract class  BaseRepository implements  BaseInterface
{

    protected $modelName;


    public function all()
    {
        // TODO: Implement getAll() method.
        $instance=$this->getNewInstance();
        return $instance->all();
    }

    public function find($id,$relation=[])
    {
        // TODO: Implement getById() method.
        $instance=$this->getNewInstance();
        return $instance->with($relation)->find($id);
    }
    protected function getNewInstance(){
        $model=$this->modelName;
        return new $model;
    }
}

namespace App\Repositories;

use App\Repositories\BaseInterface;

abstract class BaseRepository implements BaseInterface

{

protected $modelName;

public function all()

{

// TODO: Implement getAll() method.

$instance=$this->getNewInstance();

return $instance->all();

}

public function find($id,$relation=[])

{

// TODO: Implement getById() method.

$instance=$this->getNewInstance();

return $instance->with($relation)->find($id);

}

protected function getNewInstance(){

$model=$this->modelName;

return new $model;

}

Lets create a model call Test.php

<?php

namespace App\Http\Models;

use Illuminate\Database\Eloquent\Model;

class Test extends Model
{
    protected $table = 'test';
    public $timestamps = false;
    //
}

<?php

namespace App\Http\Models;

use Illuminate\Database\Eloquent\Model;

class Test extends Model

{

protected $table = 'test';

public $timestamps = false;

}

Create a Test folder in Repositories and create ITestRepository.php

<?php
/**
 * Created by IntelliJ IDEA.
 * User: Akash
 * Date: 3/31/2017
 * Time: 11:11 PM
 */
namespace App\Repositories\Test;

interface ITestRepository extends BaseInterface{
   // public function getAll();
}

<?php

/**

* Created by IntelliJ IDEA.

* User: Akash

* Date: 3/31/2017

* Time: 11:11 PM

namespace App\Repositories\Test;

interface ITestRepository extends BaseInterface{

// public function getAll();

}

and TestRepository.php

<?php
namespace App\Repositories\Test;

use App\Http\Models\Test;

class TestRepository extends BaseRepository implements ITestRepository{

    protected $modelName;

    public function __construct(Test $model){
        $this->modelName=$model;
    }

}

<?php

namespace App\Repositories\Test;

use App\Http\Models\Test;

class TestRepository extends BaseRepository implements ITestRepository{

protected $modelName;

public function __construct(Test $model){

$this->modelName=$model;

}

in AppServiceProvider.php resolve the dependency

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

use Validator;


use App\Repositories\Test\EloquentTest;
use App\Repositories\Test\TestRepository;
class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
        Validator::extend('foo', function($attribute, $value, $parameters, $validator) {
            /*if(!empty($value) && (strlen($value) % 2) == 0){
                return true;
            }*/
            return $value=='foo';
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
        $this->app->singleton(ITestRepository::class,TestRepository::class);
    }
}

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

use Validator;

use App\Repositories\Test\EloquentTest;

use App\Repositories\Test\TestRepository;

class AppServiceProvider extends ServiceProvider

{

/**

* Bootstrap any application services.

* @return void

public function boot()

{

Validator::extend('foo', function($attribute, $value, $parameters, $validator) {

/*if(!empty($value) && (strlen($value) % 2) == 0){

return true;

}*/

return $value=='foo';

});

}

/**

* Register any application services.

* @return void

public function register()

{

$this->app->singleton(ITestRepository::class,TestRepository::class);

}

Now i can use it on controller like this.
Lets create a controller TestController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Repositories\Test\TestRepository;
class TestController extends Controller
{
    private $test;
    public function __construct(TestRepository $test){
        $this->test=$test;
    }
    public function hello(){
        return $this->test->findById(1);
    }
    //
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Repositories\Test\TestRepository;

class TestController extends Controller

{

private $test;

public function __construct(TestRepository $test){

$this->test=$test;

}

public function hello(){

return $this->test->findById(1);

}

and in route file add

Route::get('/', 'TestController@hello');

1	Route::get('/', 'TestController@hello');
