Сеялка Laravel для жесткого кодирования таблицы

Question

У меня есть несколько таблиц в моей базе данных, которые просто используются для справки в моем приложении.

Например, таблица с двумя столбцами, аббревиатурой состояний и состояний и имеет все 50 состояний и их сокращения как строки.

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

Я хочу написать сеялки для этих таблиц в Laravel, так как я хочу, чтобы эти таблицы существовать, когда я начинаю новую версию приложения.

Каков наилучший способ хранения этих данных и создания этих сеялок?

Answer 1

сеялки больше, чем просто данные испытаний - и они идеально подходят для статических данных.

Это не займет слишком много времени, чтобы просто создать вручную сеялка, но вместо того, чтобы восстанавливать колесо, вы можете использовать эту любезность из ggoforth: 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(); 

     State::create(['name' => 'Alaska', 'code' => 'AK']); 
     State::create(['name' => 'Alabama', 'code' => 'AL']); 
     State::create(['name' => 'American Samoa', 'code' => 'AS']);

Answer 2

Я хотел бы использовать сырой SQL:

class DatabaseSeeder extends Seeder 
{ 
    /** 
    * Run the database seeds. 
    * 
    * @return void 
    */ 
    public function seed($table) 
    { 
     $this->command->info('Seeding '.$table); 
     $this->call($table.'TableSeeder'); 
    } 

    public function run() 
    { 
     DB::unprepared(file_get_contents(database_path('states.sql'))); 
    } 
} 

, а затем в SQL файл:

INSERT INTO `states` (`id`, `state`, `abbrev`) 
VALUES 
    (1,'Alabama', 'AL'), 
    (2,'Alaska', 'AK)...;
