Step 2: Create Table using migration

Now, We need to create a migration. so we will below command using create the students table migration.

php artisan make:migration create_students_table --create=students

1	php artisan make:migration create_students_table --create=students

After complete migration. we need below changes in the database/migrations/create_students_table file.

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateStudentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('first_name');
            $table->string('last_name');
            $table->text('address');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('students');
    }
}
?>

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateStudentsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('students', function (Blueprint $table) {

$table->bigIncrements('id');

$table->string('first_name');

$table->string('last_name');

$table->text('address');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('students');

}

Run the below command. after the changes above file.

php artisan migrate

1	php artisan migrate

Step3: Create the Model.

we create a student model using the below command.

php artisan make:model Student

1	php artisan make:model Student

Step4: Create the seeder class

we will create StudentsTableSeeder class using the below command.

php artisan make:seed StudentsTableSeeder

1	php artisan make:seed StudentsTableSeeder

Now, open the file StudentsTableSeeder.php at the database/seeds directory and replace the below content.

<?php

    use Illuminate\Database\Seeder;
    use App\Student;

    class StudentsTableSeeder extends Seeder
    {
        public function run()
        {
            
        for ($i=0; $i < 6; $i++) { 
	    	Student::create([
	            'first_name' => str_random(10),
	            'last_name' => str_random(10),
	            'address' => str_random(25)
	        ]);
    	}
          
        }
    }
?>

<?php

use Illuminate\Database\Seeder;

use App\Student;

class StudentsTableSeeder extends Seeder

{

public function run()

{

for ($i=0; $i < 6; $i++) {

Student::create([

'first_name' => str_random(10),

'last_name' => str_random(10),

'address' => str_random(25)

]);

}

When we complete the changes, then we have to need to edit the database/seeds/DatabaseSeeder.php

<?php

    use Illuminate\Database\Seeder;

    class DatabaseSeeder extends Seeder
    {
        public function run()
        {
            $this->call([
              UsersTableSeeder::class,
              StudentsTableSeeder::class,
            ]);
        }
    }
?>

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder

{

public function run()

{

$this->call([

UsersTableSeeder::class,

StudentsTableSeeder::class,

]);

}

Now, when we will execute the below command then DatabaseSeeder class is called and it will insert the records into the database.

php artisan db:seed

1	php artisan db:seed
