给大家演示一下如何快速填充数据表中的数据(推荐学习:laravel教程)

laravel5 使用tinker factory在数据表中添加测试数据
通过使用 Laravel artisan 内建的 php artisan tinker , 我们可以很方便的看到数据库中的数据并且执行各种想要的操作。
Laravel Tinker是Laravel框架的强大REPL
REPL 是指 交互式命令行界面,它可以让你输入一段代码去执行,并把执行结果直接打印到命令行界面里。
通常情况下,我们可以使用 Laravel 的模型工厂( model factory )来快速填充我们的数据库,它可以帮我向数据库插入伪数据方便我们测试。现在让我们开始使用 tinker 吧。
下面需要先安装laravel/tinker
composer require laravel/tinker
在控制台中,执行php artisan tinker
命令方可使用
打开database文件夹下的factories文件UserFactory.php文件(此文件默认存在, 直接在这里面进行操作)
也可以通过命令来创建相应的factory
php artisan make:factory ArticleFactory
编写相应的要添加的数据
<?php use Faker\Generator as Faker; $factory->define(App\Models\Article::class, function (Faker $faker) { return [ 'user_id' => rand(1,10), 'type_id' => rand(1,5), 'title' => $faker->sentence, 'content' => $faker->paragraph, ]; });
运行php artisan tinker进入tinker
factory方法的第一个参数为对应的Model类, 第二个参数为填充条数
factory(App\Models\Article::class,10)->create();
传完参数后调用create方法回车看见填充的数据出现,查看数据库,数据成功写入,均是随机生成的。
生成测试数据就完成了
exit退出tinker 命令行
