WhereNotExists Laravel Eloquent

Question

laravel雄辯框架的一點麻煩。

我需要複製這樣的查詢：

SELECT * 
FROM RepairJob 
WHERE NOT EXISTS (SELECT repair_job_id 
    FROM DismissedRequest 
    WHERE RepairJob.id = DismissedRequest.repair_job_id); 

現在我有

$repairJobs = RepairJob::with('repairJobPhoto', 'city', 'vehicle')->where('active', '=', 'Y')->whereNotExists('id', [DismissedRequest::all('repair_job_id')])->get(); 

任何人的想法？我需要把所有的repairjobs那裏沒有記錄在駁回申請表

我使用上述

Argument 1 passed to Illuminate\Database\Query\Builder::whereNotExists() must be an instance of Closure, string given 

Answer 1

嘗試doesntHave （） 方法。在RepairJob模型中假設'dismissedRequests'爲關係名稱。

$jobs = RepairJob::with('repairJobPhoto', 'city', 'vehicle') 
    ->where('active', 'Y')->doesntHave('dismissedRequests')->get(); 

Answer 2

查詢時出現此錯誤試試這個：

$repairJobs = RepairJob::with('repairJobPhoto', 'city', 'vehicle')->where('active', '=', 'Y')->whereNotExists(function($query) 
      { 
       $query->select(DB::raw(1)) 
         ->from('DismissedRequest') 
         ->whereRaw('RepairJob.id = DismissedRequest.id'); 
      })->get();
