Laravel 的 Eloquent ORM 提供了漂亮、简洁的 ActiveRecord 实现来和数据库的互动。 每个数据库表会和一个对应的「模型」互动。在开始之前,记得把 config/datab
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
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
Psy Shell v0.4.1 (PHP 5.4.16 — cli) by Justin Hileman
>>> $name = 'zhang jinglin';
=> "zhang jinglin"
>>> $name
=> "zhang jinglin"
>>> $article = new App\Article;
=>
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
表示,title, body, published_at 是可以直接填充的。
退出 tinker,重新进入
>>> $article = App\Article::create(['title' => 'New Article', 'body' => 'New body', 'published_at' => Carbon\Carbon::now()]);
=>
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。
