Let’s get started

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model & Migration

Open project into terminal and run this command to create model & migration file.

$ php artisan make:model Country -m

It will create two files –

• Model – Country.php at /app/Models folder
• Migration file – 2022_03_25_123805_create_countries_table at /database/migrations folder.

Open Migration file and write this complete code into it.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->increments('id');
            $table->string('sortname');
            $table->string('name');
            $table->string('phonecode');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('countries');
    }
};

Open model file Country.php and write this complete code into it.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Country extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Next, we need to migrate migration files.

$ php artisan migrate

This command will create tables inside database.

It will create countries table in database.

Prepare JSON Data File

As we have table countries in which columns as id, name, sortname, phonecode.

We will take a JSON file in which properties of each object will be ID, Sortname, Name & Phonecode. Rest we need data into it.

When you will download the given file it will be in .txt format. Rename file into .json and place this countries-data.json file inside /public/data folder.

Open countries-data.json file, you should see –

Create Seeder

Next, we need to create a seeder file.

$ php artisan make:seeder CountrySeeder

It will create a file CountrySeeder.php at /database/seeders folder.

Open CountrySeeder.php and write this complete code into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\Country;
use File;

class CountrySeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        //Country::truncate();

        $json = File::get(public_path("data/countries-data.json"));
        $countries = json_decode($json);
        
        foreach ($countries->countries as $key => $value) {
            Country::create([
                "sortname" => $value->sortname,
                "name" => $value->name,
                "phonecode" => $value->phoneCode
            ]);
        }

    }
}
