基于 Laravel + Vue 构建一个类似 Twitter 的 Web 应用

阅读更多关于基于 Laravel + Vue 构建一个类似 Twitter 的 Web 应用

在这一篇示例教程中，我们将会构建一个类似 Twitter 的 Web 应用。我们将使用到 Laravel 和 Vue.js，并且在 Vue.js 中定义一些组件，此外，还会使用 Axios 来发送网络请求。当然，篇幅有限，我们不可能开发一个完整的 Twitter 应用，而是实现一个简化版：用户可以发送 Tweet 并在自己的时间线中看到，可以关注或取消关注其他用户，如果关注了其他用户，那么也可以看到关注用户发布的 Tweet。麻雀虽小，五脏俱全，希望大家可以通过这个简单的应用学会 Laravel 和 Vue.js 的基础用法。安装配置 Laravel 首先，我们需要安装一个新的 Laravel 应用（也可以通过 Composer 安装，看个人喜好）： laravel new laratwitter 进入该项目根目录，安装前端依赖： npm install 接下来，修改 .env 中数据库相关配置符合本地环境，然后通过如下命令生成用户认证脚手架代码： php artisan make :auth 运行如下命令生成相关数据表： php artisan migrate 接下来配置下 Web 服务器（使用 Valet 的话略过），我这里配置的域名是 laratwitter.test ，配置完成后重启下 Web 服务器，然后通过 http://laratwitter.test

阅读更多关于 List of users with the highest sum of points

问题 I would like to create a ranking ordered by the user who has the most "points" scored. My "points" table has these fields: user_id, type and quantity. In this example, user 1 has a total of 4 points, while user 2 has a total of 8. My dilemma after several unsuccessful tests, is to create a cycle that shows users with the highest sum of "quantity".
