Laravel 5 の基礎 (7) - Eloquent (laravel の ORM)
<code>php artisan make:model Article#输出Model created successfully.Created Migration: 2015_03_28_062517_create_articles_table</code>
生成されたファイルを確認してみるapp/Article.php
<code><?php namespace App;use Illuminate\Database\Eloquent\Model;class Article extends Model { //}</code>
Model を継承する以外に特別なことはありませんが、強力な機能があり、それらはすべて Laravel の Model にカプセル化されています。このモデルは、save() update() findXXX()
などの強力な機能を自動的に備えています。
