            $subform->hasMany('triage_tags', "分诊标签", function (Form\NestedForm $nestedForm) {
                $nestedForm->hidden('id');
                $nestedForm->select('name', "标签")->options(TriageTag::all()->pluck('name', 'name'));
                //$nestedForm->text('name', "标签");

laravel log

use Illuminate\Support\Facades\Log;

Log::info("triageTeam" . json_encode($triageTeam));
Log::info("schools" . json_encode($triageTeam->schools()));

强制使用dd($variable)能在页面打印变量 很好用

php-fpm

php-fpm 是以守护进程形式执行php进程 以便下游服务器发送cgi通信数据过来 然后通过标准输出流返回网页数据到 cgi服务器

具体关键配置

进程owner 用户（权限相关） 

user = www-data
group = www-data

listen.acl_users = apache,nginx,www-data
 //允许访问的用户

子进程数量限制 （性能相关）

监听方式（unix file socket 或者 tcp ip socket）(注意unix:socket 方式需设定该文件读写权限)

listen = /run/php-fpm/www.sock
listen.owner = nobody
listen.group = nobody
listen.mode = 0660


listen = 127.0.0.1:6000
listen.allowed_clients = 127.0.0.1

nginx 下 laravel 部署

server {
                listen       8080;
                server_name  laravel.localhost;

                client_max_body_size 10M;
                # Load configuration files for the default server block.

                

                location / {
                        root           D://robin-admin/public;
                        index  index.html index.htm index.php;
                        try_files $uri $uri/ /index.php?$query_string;
                }

                location ~ \.php$ {
                    root           D://robin-admin/public;
                    fastcgi_pass   127.0.0.1:9000;
                    fastcgi_index  index.php;
                    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                    include        fastcgi_params;
                }

                error_page 404 /404.html;
                        location = /40x.html {
                }

                error_page 500 502 503 504 /50x.html;
                        location = /50x.html {
                }
    }

nginx 根目录指向laravel 的下的public 文件夹

try_files $uri $uri/ /index.php?$query_string; 可以有效重新访问后缀（不需要显式指明php后缀）

php artisan tinker

今天，我们将通过介绍 Laravel 中一个不太为人所知的功能，来展示如何快捷的调试数据库中的数据。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 artisan 的 tinker 是一个 REPL (read-eval-print-loop)，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。

// see the count of all users
App\User::count();

// find a specific user and see their attributes
App\User::where('username', 'samuel')->first();

// find the relationships of a user
$user = App\User::with('posts')->first();
$user->posts;
factory(App\User::class, 10)->create();
App\User::all();
App\User::count();
$user = new App\User;
$user->name = "Wruce Bayne";
$user->email = "iambatman@savegotham.com";
$user->save();

php __call

__call 属于php 类对象的magic 方法

当调用一个不存在与类定义的方法 就会 在call中调用

 function __call($name,$arguments) {  

 }

$name 为方法名字

$argument 为方法参数
