Laravel Repository Pattern Implementation

Originally published at https://github.com

Installation

composer require salmanzafar/laravel-repository-pattern 

Features

Will generate all the functionality for Repository pattern implementation

• ServiceClass
• Interface
• ServiceProvider

Enable the package (Optional)

This package implements Laravel auto-discovery feature. After you install it the package provider and facade are added automatically for Laravel >= 5.5.

Configuration

Publish the configuration file

This step is required

php artisan vendor:publish --provider="Salman\RepositoryPattern\RepositoryPatterServiceProvider" 

Usage

After publishing the configuration file just run the below command

php artisan make:repo ModelName 

That's it, Now you've successfully implemented the repository pattern

Example

php artisan make:repo Car

CarRepositoryInterface.php

<?php
namespace App\Repositories;
interface CarRepositoryInterface

{

/**

* Get’s a record by it’s ID

*

* @param int

*/

public function get($id);
/**
 * Get's all records.
 *
 * @return mixed
 */
public function all();

/**
 * Deletes a record.
 *
 * @param int
 */
public function delete($id);

/**
 * Updates a record.
 *
 * @param int
 * @param array
 */
public function update($id, array $data);

}

CarRepository.php

<?php

namespace App\Repositories;
use App\Car;
class CarRepository implements CarRepositoryInterface

{

/**

* Get’s a record by it’s ID

*

* @param int

* @return collection

*/

public function get($id)

{

return Car::find($id);

}
/**
 * Get's all records.
 *
 * @return mixed
 */
public function all()
{
    return Car::all();
}

/**
 * Deletes a record.
 *
 * @param int
 */
public function delete($id)
{
    Car::destroy($id);
}

/**
 * Updates a post.
 *
 * @param int
 * @param array
 */
public function update($id, array $data)
{
    Car::find($id)-&gt;update($data);
}

}

Now go to

Repositories/RepositoryBackendServiceProvider.php and register the interface and class you have’just created

<?php

namespace App\Repositories;
use Illuminate\Support\ServiceProvider;
class RepositoryBackendServiceProvider extends ServiceProvider

{
public function register()
{
    $this-&gt;app-&gt;bind(
        /*
        * Register your Repository classes and interface here
        **/

        'App\Repositories\CarRepositoryInterface',
        'App\Repositories\CarRepository'
    );
}

}

And now in your app/Http/Controllers/Carcontroller

<?php

namespace App\Http\Controllers;
use App\Car;

use App\Repositories\CarRepositoryInterface;
class CarController extends Controller

{

protected $car;
public function __construct(CarRepositoryInterface $car)
{
    $this-&gt;$car = $car;
}

/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    $data = $this-&gt;car-&gt;all();

    return $data;
}

}

That’s it you’ve successfully implemented Repository pattern in your code.

Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [
        'name','description'
    ];
}

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.

routes/web.php

Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);
