問題描述
laravel 的雄辯框架有點小麻煩.
Little bit of trouble with the eloquent framework for laravel.
我需要復制這樣的查詢:
I need to replicate a query like this :
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();
有人有什么想法嗎?我需要獲取在已駁回請求表中沒有記錄的所有維修作業
Anyone an idea? I need to get all the repairjobs where there is no record for in the dismissed requests table
使用上述查詢時出現此錯誤
I get this error when using the query above
Argument 1 passed to IlluminateDatabaseQueryBuilder::whereNotExists() must be an instance of Closure, string given
推薦答案
嘗試 dontHave() 方法.假設dismissedRequests"作為 RepairJob 模型中的關系名稱.
Try doesntHave() method. Assuming 'dismissedRequests' as relation name in RepairJob model.
$jobs = RepairJob::with('repairJobPhoto', 'city', 'vehicle')
->where('active', 'Y')->doesntHave('dismissedRequests')->get();
