我刚刚学会了模型观察者,并希望将我的一些逻辑从控制器转移到观察者。这就是我所拥有的:
AppServiceProvider.php
public function boot()
{
WorkOrder::observe(WorkOrderObserver::class);
}
WorkOrderObserver.php
namespace App\Observers;
use App\Site;
use App\WorkOrder;
use Carbon\Carbon;
use App\WorkOrderNumber;
class WorkOrderObserver
{
public function creating(WorkOrder $workOrder)
{
$branchOfficeId = Site::findOrFail($request->site_id)->branch_office_id;
$today = Carbon::today('America/Los_Angeles');
$todaysWorkOrderCount = WorkOrder::where('created_at_pst', '>=', $today)->count();
$workOrder->work_order_number = (new WorkOrderNumber)
->createWorkOrderNumber($branchOfficeId, $todaysWorkOrderCount);
$workOrder->completed_by = null;
$workOrder->status_id = 1;
$workOrder->work_order_billing_status_id = 1;
$workOrder->created_at_pst = Carbon::now()->timezone('America/Los_Angeles')
->toDateTimeString();
}
}
问题是从观察者中访问请求。我在文档中看不到任何内容。我发现这里有一个引用这个的线程,它建议使用请求帮助函数。我试过request('site_id')
,但它是空的。

这很简单我发布它有点尴尬。无论如何,如果有人找到这个帖子,这就是解决方案。在您的观察者中,添加一个接受请求并设置属性的构造函数。
int i =cmd.ExecuteNonQuery();
if(i>0)
{
this.BindGrid();
}

您可以使用Laravel的应用帮助功能请求对象。
protected $request;
public function __construct(WorkOrderNumber $workorder)
{
$this->request = app('request');
}
