【原创】Laravel 中填充模拟数据

创建模型

php artisan make:model Match

<?php

namespace App\Models;

use EloquentFilter\Filterable;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Match extends Model
{
    use HasFactory;
    protected $table = 'xxx_match';
    public $timestamps = false;
}

默认情况下，Eloquent 会预计你的数据表中有 created_at 和 updated_at 字段。如果你不希望自动维护这两个字段，可在模型内将 $timestamps 属性设置为 false。

创建工厂

php artisan make:factory MatchFactory

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;

class MatchFactory extends Factory
{
    protected $mas = ['aaa', 'ccc', 'vvv', 'xxx', 'aaa'];
    protected $users = ['ee', 'ddd', 'bb', 'cc', 'aa'];
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'a' => 'C' . rand(1000000,9999999),
            'c' => $this->getRandData($this->mas),
            'v' => (string)rand(100000, 999999),
            'f' => rand(1,2),
            'g' => '',
            'h' => rand(1,4),
            'l' => rand(1,4),
            'b' => $this->getRandData($this->users),
            'm' => $this->getRandData($this->users),
        ];
    }

    protected function getRandData($data)
    {
        return $data[rand(0,4)];
    }
}

创建填充文件

php artisan make:seeder MatchSeeder

<?php

namespace Database\Seeders;

use App\Models\Match;
use Illuminate\Database\Seeder;

class MatchSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Match::factory()->count(20000)->create();
    }
}

填充数据

php artisan db:seed --class=MatchSeeder
