How to migrate single migration in laravel

Sometimes while working on a laravel application, we just need to migrate only single or specific migration. If we run normal migrate command it will migrate all the migrations written in the application. Here i will let you know to migrate single migration in laravel.

Migrations play very important role for aplication’s database structure. We just need to create migrations in the application for each table which you want and whenever we migrate these migrations. New table structure would be created.

For new developers or setting up new environment, we do not need to backup of table structure. We will just need to run the migrations. It will automatically create desired tables in the database connected from the laravel application.

We can run all the migrations using the command below.

php artisan migrate

Now if we want to run only one migration or a specific migration, we will need to define a path parameter and will need to specify the path of that migration file which we want to run like below.

php artisan migrate --path=/database/migrations/my_migration.php

It will migrate only my_migration.php file. Here, you will need to replace file name from your own migration file.

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

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']);
