Question

laravel的雄辩框架有点麻烦。

我需要像这样复制一个查询：

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

现在我有

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

有人有想法吗？我需要获取所有在被解雇的请求表中没有记录的repairjobs

使用上面的查询时出现此错误

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

Answer 1

尝试使用doesntHave（）方法。假设在RepairJob模型中将'dismissedRequests'作为关系名称。

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