What's New in Laravel v8.61

The Laravel team released 8.61 with a delete or fail() model method, a value or fail model method, assert if a model exists in a test and the latest changes in the v8.x branch.

Delete or Fail Model Method

Claas Augner contributed a deleteOrFail() method that makes it more convenient to handle model delete errors and less verbose than checking the return value of delete():

1try {2    $model->deleteOrFail();3} catch (\Throwable $e) {4    // ...5}

Assert If a Model Exists Test Method

@RVxLab contributed a assertModelExists() testing method to test whether a model exists in the database. Taylor Otwell also added a assertModelMissing method:

 1$product = Product::find(1); 2  3// ... 4$this->assertDatabaseHas('products', [ 5    'id' => $product->getKey(), 6]); 7  8$this->assertModelExists($product); 9 10$this->assertModelMissing($product);

Value or Fail Model Method

In the only new feature of Laravel 8.60, @Italo contributed a valueOrFail() method, which gets a single column's value from the first result of a query or throws an exception:

1// Before:2$votes = User::where('name', 'John')->firstOrFail('votes')->votes;3 4// Now:5$votes = User::where('name', 'John')->valueOrFail('votes');

Allows Tests to Utilize the Null Logger

Tim MacDonald contributed a new update where tests can utilize the null logger. Check out Pull Request #38785 for more details on the situation and updates made.

Create a Policy While Creating a Model

Tim Fevens contributed a --policy flag, which is also included with the --all flag as well:

1php artisan make:model --policy Post

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']);

How to perform migration rollback in laravel

As we know that laravel migration provides very simple way to create database table structure. We need to create migration file and write table structure then migrate that migration. Sometimes we need to rollback that migration. So here we will discuss about the migration rollback in laravel.

We can run the rollback artisan command to rollback on a particular step. We can execute the following artisan command.

php artisan migrate:rollback --step=1

Every time when we will rollback, we will get the last batch of migration.

**Note: **This rollback command will work on laravel 5.3 or above version. For the version below 5.3, there is no command available for migration rollback in laravel.

We can also use the following command to rollback and re migrate.

php artisan migrate:refresh --step=2

It will rollback and remigrate last two migration.
