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;
条件をつけて1行取得
$article = \App\Article::where('active', 1)->first();
条件をつけて複数行取得
$articles = \App\Article::where('active', 1)->get();
limitを指定して取得
$articles = \App\Article::where('active', 1)->take(10)->get();
挿入
$article = new \App\Article(); $article->title = 'net'; $article->save();
更新
$article = \App\Article::find(2); $article->title = 'it'; $article->save();
削除
$article = \App\Article::find(2); $article->delete();
スコープ
// 挿入 public static function insertName($name, $url) { $row = new get_class($self); $row->url = $url; $row->name = $name; $row->save(); } \App\Test::insertName('name1', 'url1');
// 取得 public static function findRowByName($name) { return self::where('name', $name)->first(); } \App\Test::findRowByName('name1');
