Laravel数据填充

框架：Laravel
版本：5.5.21

• 生成Factory

$ php artisan make:factory StudentsFactory

• 生成Seeder

$ php artisan make:seeder StudentsTableSeeder

• 填充Factory生成规则：database/factories/StudentFactory

$factory->define(Student::class, function (Faker $faker) {
    $time = date('Y-m-d H:i:s');
    return [
        'name' => $faker->unique()->name,
        'age' => rand(1,120),
        'sex' => rand(0,2),
        'created_at' => $time,
        'updated_at' => $time,
    ];
});

• 填充Seeder数据：database/seeds/StudentsTableSeeder

public function run()
{
    $students = factory(\App\Models\Student::class)->times(300)->make();
    \App\Models\Student::insert($students->toArray());
}

• 添加Seeder到DatabaseSeeder：database/seeds/StudentsTableSeeder

public function run()
{
    $this->call(StudentsTableSeeder::class);
}

• 运行数据填充命令，收工

$ php artisan db:seed --class=StudentsTableSeeder
