What is a way that I can make a button to spawn infinite forms? Any method would work, but I just can't think of any. This is kind of the layout I am thinking of Country | Province | Topic | China | Beijing | Flood | (+) China | Shaanxi | Flood | (+) In this imaginary example, the plus button would spawn another form where the values would be ident
什么是我可以制作按钮以产生无限形式的方式? 任何方法都可行,但我无法想到任何方法。 这是我想到的布局 Country | Province | Topic | China | Beijing | Flood | (+) China | Shaanxi | Flood | (+) 在这个虚构的例子中,加号按钮会产生另一种形式,其值将是相同的,但如果一个事件影响多个地方,则允许用户更改一个字段。 您可以使用jQuery随时创建表单元素,然后使用append

I need to scale my mysql RDS instance. I can launch read replicas in amazon RDS, but problem is that the write operations won't work on read replicas. I need to redirect all the write operations (INSERT, UPDATE, DELETE) on master server somehow, and all the read operations on a read replica. RDS will take care of synchronizing the read replica with latest changes. is there any easy way
我需要扩展我的mysql RDS实例。 我可以在amazon RDS中启动只读副本,但问题是写操作无法在只读副本上工作。 我需要以某种方式重定向主服务器上的所有写操作(INSERT,UPDATE,DELETE),以及读副本上的所有读操作。 RDS将负责将读取副本与最新更改同步。 有没有简单的方法来修改蛋糕来执行不同的数据库上的所有写命令? 无需更改控制器或型号? 我现有的服务器无法处理连接和cpu峰值。 已经尝试升级它,但没有奏效。
so i am learning laravel and so far i have built an application with signup and sign in and some data which can be stored in the database. now i have 2 models: the users model which has its own validation set of rules, and another model contact which has its own set of rules.Taking a closer look at how laravel generates its models they both inherit from a base class called Eloquent. what i wou
所以我正在学习laravel,到目前为止,我已经构建了一个注册和登录应用程序以及一些可以存储在数据库中的数据。 现在我有两个模型:拥有自己的验证规则集的用户模型,以及具有自己的一组规则的另一个模型联系人。仔细研究laravel如何生成其模型,它们都从称为Eloquent的基类继承。 我想要的是一个多态的“isValid”函数,它只是验证用户输入与在函数被调用的类中创建的一组规则。但是现在,当我创建联系人模型时,我发现自己重复
I'm having a strange problem on Laravel 5.5. I'm using PhpStorm and am trying to use it to make a phpunit call on my Vagrant host to PHPUnit like this: vagrant:///Users/mymachine/Webdev/project/usr/bin/php -dxdebug.coverage_enable=1 /home/vagrant/project/vendor/phpunit/phpunit/phpunit --coverage-clover /home/vagrant/.phpstorm_helpers/project_AdminLoginTest_coverage --bootstrap /home/va
我在Laravel 5.5上遇到了一个奇怪的问题。 我正在使用PhpStorm,并试图使用它来将我的Vagrant主机上的phpunit调用改为PHPUnit,如下所示: 流浪汉:///用户/ mymachine上/ Webdev的/项目的/ usr / bin中/ PHP -dxdebug.coverage_enable = 1 /家庭/流浪者/项目/供应商/ PHPUnit的/ PHPUnit的/ PHPUnit的--coverage三叶草/home/vagrant/.phpstorm_helpers / project_AdminLoginTest_coverage --bootstrap /home/vagrant/project

我试图在我的/ tests /目录中添加一些结构,目前文件的结构如下所示: /测试 /楷模 UserTest.php ExampleTest.php TestCase.php UserTest和ExampleTest都是从TestCase扩展而来的。 运行Exampletest工作得很好(将用户添加到数据库),而UserTest失败并出现以下错误: 致命错误:调用第3340行的 Illuminate Datab ase Eloquent Model.php中的null成员函数connection() 这意味着这个函数接收null或没有参数
I'm adding validation to a BaseModel class which all eloquent models will eventually extend in my application. The base class resembles: class BaseModel extends Eloquent { private $errors; private $validator; public function __construct() { $this->validator = new BaseValidator(get_class($this)); } public static function boot() { parent::boot(); static::creating(function($
我将验证添加到BaseModel类中,所有雄辩的模型最终将在我的应用程序中扩展。 基类类似于: class BaseModel extends Eloquent { private $errors; private $validator; public function __construct() { $this->validator = new BaseValidator(get_class($this)); } public static function boot() { parent::boot(); static::creating(function($model) { return false; }); static::sa
I'm trying to simulate what Ardent package is doing. Which is validating a model right before saving. I've created this BaseModel (According to Laravel Testing decoded book). And added this code : class BaseModel extends Eloquent { protected static $rules = []; public $errors = []; public function validate(){ $v = Validator::make($this->attributes, static::$ru
我试图模拟Ardent软件包在做什么。 保存前正在验证模型。 我已经创建了这个BaseModel (根据Laravel Testing decoded书)。 并添加了以下代码: class BaseModel extends Eloquent { protected static $rules = []; public $errors = []; public function validate(){ $v = Validator::make($this->attributes, static::$rules); if($v->passes()) { return true;
