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)
如果你想用seeder来填充数据请跳转:https://www.php.cn/phpkj/laravel/483789.html
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

Laravel stands out by simplifying the web development process and delivering powerful features. Its advantages include: 1) concise syntax and powerful ORM system, 2) efficient routing and authentication system, 3) rich third-party library support, allowing developers to focus on writing elegant code and improve development efficiency.

Laravel and Python have their own advantages and disadvantages in terms of performance and scalability. Laravel improves performance through asynchronous processing and queueing systems, but due to PHP limitations, there may be bottlenecks when high concurrency is present; Python performs well with the asynchronous framework and a powerful library ecosystem, but is affected by GIL in a multi-threaded environment.

Laravel is suitable for projects that teams are familiar with PHP and require rich features, while Python frameworks depend on project requirements. 1.Laravel provides elegant syntax and rich features, suitable for projects that require rapid development and flexibility. 2. Django is suitable for complex applications because of its "battery inclusion" concept. 3.Flask is suitable for fast prototypes and small projects, providing great flexibility.

Laravel can be used for front-end development. 1) Use the Blade template engine to generate HTML. 2) Integrate Vite to manage front-end resources. 3) Build SPA, PWA or static website. 4) Combine routing, middleware and EloquentORM to create a complete web application.

PHP and Laravel can be used to build efficient server-side applications. 1.PHP is an open source scripting language suitable for web development. 2.Laravel provides routing, controller, EloquentORM, Blade template engine and other functions to simplify development. 3. Improve application performance and security through caching, code optimization and security measures. 4. Test and deployment strategies to ensure stable operation of applications.

Laravel and Python have their own advantages and disadvantages in terms of learning curve and ease of use. Laravel is suitable for rapid development of web applications. The learning curve is relatively flat, but it takes time to master advanced functions. Python's grammar is concise and the learning curve is flat, but dynamic type systems need to be cautious.

Laravel's advantages in back-end development include: 1) elegant syntax and EloquentORM simplify the development process; 2) rich ecosystem and active community support; 3) improved development efficiency and code quality. Laravel's design allows developers to develop more efficiently and improve code quality through its powerful features and tools.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
