laravel seeder 数据填充

1：生成一个模型

$ php artisan make:model Post -m

2：填写posts的迁移表的字段内容

Schema::create('posts', function (Blueprint $table) {
 $table->increments('id');
 $table->string("title");
 $table->string("content");
 $table->integer('view_count')->unsigned();
 $table->timestamps();
});

3：新建一个填充类

php artisan make:seeder PostTableSeeder

4:在DatabaseSeeder类run()方法中，使用call方法获取要运行的填充器类：

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;


class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Model::unguard();
        $this->call('PostTableSeeder');
        Model::reguard();

    }
}

5:填写新建的类

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;


class PostTableSeeder extends Seeder
{
    public function run()
    {
        App\Post::truncate();
        factory(App\Post::class, 1000)->create();
    }
}

6:文件目录\database\factories\ModelFactory.php添加迁移内容

$factory->define(App\Post::class, function (Faker\Generator $faker) {
    return [
        'title' => $faker->sentence,
        'content' => $faker->paragraph,
        'view_count' => 0
    ];
});
