Laravel8 uses faker to call factory to fill data

1. Install the population file through the command .

php artisan make:seeder UserSeeder

2. stay database Find our fill file

3. Write the function method in our fill file

// Write seed file （ Use Chinese package ）
        $faker = Factory::create('zh_CN');

        // How much test data to fill according to our needs （ I am here 20 So it's filling 20 Data ）
        for ($i = 0; $i <= 20; $i++) {
            // Call the model to fill in the data 
            UddModel::create([
                'username' => $faker->name,
                'password' => bcrypt('123456'),]);
//             notes ： Add the creation time field in the process of filling data （updated_at） And modify the time field （updated_at） Prevent filling errors 
        }

4. Execute our fill file to generate fill data

php artisan db:seed --class=UserSeeder
