Seeders tutorial in Laravel 11

 <?php


namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\student;
use Illuminate\Support\Facades\File;

class StudentSeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        for ($i = 1; $i <= 10; $i++) {
            student::create([
                "name" => fake()->name(),
                "email" => fake()->unique()->email()
            ]);
        }




        // $json = File::get(path: "database/json/students.json");
        // // To use sub methods of collect(), we have used collect() as shown below :
        // $students = collect(json_decode($json)); //json_decode() converts json to Array

        // // When we create table and if we insert data in table using "create()" method at that time
        // // we must have to use "timestamps()" column while creating table because "create()" method
        // // needs to add two column values "created_at" and "updated_at" in table that's why we must
        // // use "timestamps()" column but if we use old method "insert()" instead of "create()" then
        // // there is no need to use "timestamps()" method

        // $students->each(function ($stu) {
        //     student::create([
        //         "name" => $stu->name,
        //         "email" => $stu->email
        //     ]);
        // });
    }
