php - 用于硬编码表的 Laravel 播种机

Question

我的数据库中有几个表，仅供我的应用程序引用。

例如，一个表有两列，州和州缩写，并且将所有 50 个州及其缩写作为行。

State       | State Abbreviation
Alabama     | AL
Alaska      | AK
...

我想在 Laravel 中为这些表编写播种器，因为我希望这些表在我启动新版本的应用程序时存在。

存储这些数据和创建这些播种机的最佳方式是什么？

Answer 1

播种机不仅仅适用于测试数据——而且它们非常适合静态数据。

手动创建播种器不会花太长时间，但您可以使用 ggoforth 提供的资源代替重建轮子:https://github.com/ggoforth/laravel-5-us-states-seeder/blob/master/StatesSeeder.php

<?php

use App\State;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;

class StatesSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {

        DB::table('states')->truncate();
