我们来生成第一个模型
复制代码 代码如下:
php artisan make:model Article
#输出
Model created successfully.
Created Migration: 2015_03_28_062517_create_articles_table
查看一下生成的文件 app/Article.php

修改我们的模型文件 Article.php
<"htmlcode">> $article = App\Article::create(['title' => 'New Article', 'body' => 'New body', 'published_at' => Carbon\Carbon::now()]); => <App\Article #000000005051b2c7000000007ec432dd> { title: "New Article", body: "New body", published_at: <Carbon\Carbon #000000005051b2c6000000007ec4081d> { date: "2015-03-28 06:55:19", timezone_type: 3, timezone: "UTC" }, updated_at: "2015-03-28 06:55:19", created_at: "2015-03-28 06:55:19", id: 2 } # It's ok > App\Article::all()->toArray(); => [ [ "id" => "1", "title" => "My First Update Title", "body" => "Some content...", "published_at" => "2015-03-28 06:37:22", "created_at" => "2015-03-28 06:38:53", "updated_at" => "2015-03-28 06:42:03" ], [ "id" => "2", "title" => "New Article", "body" => "New body", "published_at" => "2015-03-28 06:55:19", "created_at" => "2015-03-28 06:55:19", "updated_at" => "2015-03-28 06:55:19" ] ] > $article = App\Article::find(2); => <App\Article #000000005051b22b000000007ec432dd> { id: "2", title: "New Article", body: "New body", published_at: "2015-03-28 06:55:19", created_at: "2015-03-28 06:55:19", updated_at: "2015-03-28 06:55:19" } > $article->update(['body' => 'New Updaet Body']); => true #update自动调用save()以上所述就是本文的全部内容了,希望能够对大家学习Laravel5框架有所帮助。
