How to seed database in yii2?

I am new to Yii framework. I want to seed my database like it can be done in Laravel framework using Faker. I tried this http://www.yiiframework.com/forum/index.php/topic/59655-how-to-seed-yii2-database/ but it does not provide much details. I would really appreciate if someone can help me out with the steps in details.

You can also use batch insert if you do not want any validations and simply pass arrays to your custom console command like.

<?php
namespace app\commands;
use Yii;
use yii\console\Controller;
use yii\console\ExitCode;
use yii\db\Command;

class SeedController extends Controller
{
    
       

   
    public function actionUsers()
    {
        Yii::$app->db->createCommand()->batchInsert('users',
        [ 
            'username',
            'password',            
            'createdAt' ,
            'updatedAt'
            ],
            [

               ['user1', 'yourhashedpass', new \yii\db\Expression('NOW()'),new \yii\db\Expression('NOW()')],
['user2', 'yourhashedpass', new \yii\db\Expression('NOW()'),new \yii\db\Expression('NOW()')],
 
                
        ])->execute();
 return ExitCode::OK;

    }
}

And run it by

php yii seed/users

Creating console command and using Faker inside the console command controller to seed the database worked for me.
Following is the SeedController.php file which I created under commands folder: 

// commands/SeedController.php
namespace app\commands;

use yii\console\Controller;
use app\models\Users;
use app\models\Profile;

class SeedController extends Controller
{
    public function actionIndex()
    {
        $faker = \Faker\Factory::create();

        $user = new Users();
        $profile = new Profile();
        for ( $i = 1; $i <= 20; $i++ )
        {
            $user->setIsNewRecord(true);
            $user->user_id = null;

            $user->username = $faker->username;
            $user->password = '123456';
            if ( $user->save() )
            {
                $profile->setIsNewRecord(true);
                $profile->user_id = null;

                $profile->user_id = $user->user_id;
                $profile->email = $faker->email;
                $profile->first_name = $faker->firstName;
                $profile->last_name = $faker->lastName;
                $profile->save();
            }
        }

    }
}

And used yii seed command to run the controller.

See at fixtures and faker realization in yii2-app-advanced tests. In project you also can write in console php yii fixture/load to load seeds in database and php yii fixture/generate-all to generate seed by faker.

yii.php should have right fixture controller in controllerMap array:

[
    'controllerMap' => [
        'fixture' => [
            'class' => 'yii\console\controllers\FixtureController',
            'namespace' => 'common\ActiveRecords'
        ]
    ]
]

See more info in documentation.
