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
<?php namespace app;
use illuminatedatabaseeloquentmodel;
class article extends model {
//
}
没什么特别的，除了继承自 model 以外，但是具有强大的功能，这些都封装在laravel的model中。模型自动具有了 save() update() findxxx() 等强大的功能。
tinker 是 laravel提供的命令行工具，可以和项目进行交互。
php artisan tinker
#以下是在tinker中的交互输入

illuminatedatabaseeloquentmassassignmentexception with message 'title'
massassignmentexception，laravel保护我们不能直接插入记录。比如，在一些特殊情况下我们需要直接利用表单的信息填充数据库记录，但是如果我们并没有在表单中添加密码字段，而黑客产生了密码字段连同我们的其他字段一起送回服务器，这将产生修改密码的危险，所以我们必须明确的告诉laravel我们的模型那些字段是可以直接填充的。
修改我们的模型文件 article.php
<?php namespace app;
use illuminatedatabaseeloquentmodel;
class article extends model {
protected $fillable = [
'title',
'body',
'published_at'
];
}
表示，title, body, published_at 是可以直接填充的。
退出 tinker，重新进入
>>> $article = apparticle::create(['title' => 'new article', 'body' => 'new body', 'published_at' => carboncarbon::now()]);
=> <apparticle #000000005051b2c7000000007ec432dd> {
title: "new article",
body: "new body",
published_at: <carboncarbon #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
>>> apparticle::all()->toarray();
=> [
[
"id" => "1",
"title" => "my first update title",
"body" => "some content...",
"published_at" => "2015-03-28 06:37:22",

#update自动调用save()
