Eloquent ORMをつかう

モデル自動生成

php artisan make:model Article

vi app/Article.php

<?php namespace App;
use Illuminate\Database\Eloquent\Model;
class Article extends Model
{
    protected $primaryKey = 'id';
    protected $table = 'articles';
    public $timestamps = true;
}

table作成

CREATE TABLE `articles` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `created_at` datetime NOT NULL,
 `updated_at` datetime NOT NULL,
 `title` varchar(63) DEFAULT NULL,
 `body` text NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

timestamps設定について

1を設定するとcreated_atとupdated_atに挿入・更新時、自動で日付が入る

| id | created_at          | updated_at          | title | body |
+----+---------------------+---------------------+-------+------+
|  1 | 2016-02-18 22:40:14 | 2016-02-18 22:40:14 | net   |      |

全取得

vi app/Http/Controllers/ArticleController.php

$articles = \App\Article::all();
foreach ($articles as $article) {
    echo $article->id."\n";
    echo $article->title."\n";
}

取得

$article = \App\Article::find(2); // primary keyを引数に入れる // App\Article Objectが返ってくる
echo $article->title;

挿入

$article = new Article();
$article->title = 'net';
$article->save();

更新

$article = Article::find(2);
$article->title = 'it';
$article->save();

削除

$article = Article::find(2);
$article->delete();
