$table->id(); // increment value
$table->string('title')->comment('this is blog title');
$table->string('slug')->unique();
$table->text('short_desc');
$table->longText('description');

// Let's say you want starting value from 1000
$table->id()->from(1000); // increment value start from 1000

->nullable(true) // boolean value

->default(your value);

//We can apply unique()

$table->string('slug')->unique();

or

$table->unique(['columnName1', 'columnName2']);

//Creating UUID:

Laravel has seeder feature, To insert some master data in database while migrating. 

php artisan make:seeder UserSeeder

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;

use Illuminate\Database\Seeder;

use Illuminate\Support\Facades\DB;

use Illuminate\Support\Str;

use Illuminate\Support\Facades\Hash;

use Carbon\Carbon;

class UserSeeder extends Seeder

{

    /**

     * Run the database seeds.

     */

    public function run(): void

    {

        $users = [

            [

                'user_id' => '4bace869-9bc0-424c-9292-111dac5b7ee7',

                'first_name' => 'Admin',

                'middle_name' => 'D',

                'last_name' => 'Doe',

                'email' => 'admin@mailinator.com',

                'password' => Hash::make('India@123'),

                'role_id' => 1,

                'created_at' => now(),

                'updated_at' => now(),

            ],

            [

                'user_id' => Str::uuid(),

                'first_name' => 'Jane',

                'middle_name' => 'E',

                'last_name' => 'Smith',

                'email' => 'sid@mailinator.com',

                'password' => Hash::make('India@123'),

                'role_id' => 2,

                'created_at' => now(),

                'updated_at' => now(),

            ],

            [

                'user_id' => Str::uuid(),

                'first_name' => 'Alice',

                'middle_name' => 'F',

                'last_name' => 'Johnson',

                'email' => 'alice.johnson@example.com',

                'password' => Hash::make('password'),

                'role_id' => 1,

                'created_at' => now(),

                'updated_at' => now(),

            ],

            // Add more users as needed

        ];

        // Insert users and create profiles

        foreach ($users as $user) {

            DB::table('users')->insert($user);

            $profileData = [

                'user_id' => $user['user_id'],

                'kyc_status' => 'Pending',

                'dob' => Carbon::now()->format('Y-m-d'), // Adjust as needed

                'account_type' => $user['role_id'] === 1 ? 'Corporate' : ($user['role_id'] === 2 ? 'Personal' : 'Personal'),

                'sex' => 'Male', // Adjust as needed

                'phone_no' => '1234567890', // Adjust as needed

                'country_id' => 1, // Adjust as needed

            ];

            if ($profileData['account_type'] === 'Corporate') {

                $profileData['company'] = 'Example Corp';

                $profileData['company_sector'] = 'Technology';

                $profileData['company_address'] = '1234 Example St';

            }

            DB::table('profiles')->insert($profileData);

        }

    }

}

After this you need to update userSeeder on databaseSeeder.php

<?php

namespace Database\Seeders;

use App\Models\User;

// use Illuminate\Database\Console\Seeds\WithoutModelEvents;

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder

{

    /**

     * Seed the application's database.

     */

    public function run(): void

    {

        // User::factory(10)->create();

        // User::factory()->create([

        //     'name' => 'Test User',

        //     'email' => 'test@example.com',

        // ]);

        // Call the UserSeeder

        $this->call(UserSeeder::class);       

    }

}

and then finally run migrate

php artisan migrate:fresh --seed
