laravel - 带有连接的 yajra DataTable 在 laravel 5 中不起作用？

Question

客户与工作的关系

 public function customer() {
        return $this->belongsTo('App\Customer','customerid');
    }

  public function jobs(){
        return $this->hasMany('App\Job','customerid');
    }

在 Controller 中

protected  function getJobs(){
			$jobs = Job::Join('customer','jobs.customerid','=','customer.id')
            ->select(array('jobs.id','customer.firstname','customer.lastname','jobs.jobstatus','jobs.trialdate','jobs.deliverydate'));	
        return Datatables::of($jobs)
            ->addColumn('action', '<a class="btn btn-default btn-xs" data-toggle="tooltip" data-placement="top" title="Edit" href="{{ URL::to(\'updatejob/\'.$id) }}"><i class="fa fa-pencil"></i></a>')
            ->make();
			
    }

它抛出以下错误

SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'order clause' (SQL: select `jobs`.`id`, `customer`.`firstname`, `customer`.`lastname`, `jobs`.`jobstatus`, `jobs`.`trialdate`, `jobs`.`deliverydate` from `jobs` inner join `customer` on `jobs`.`customerid` = `customer`.`id` order by `0` asc limit 10 offset 0)

我从 2 天起就被困在这个问题上，请帮助我摆脱这个问题

我认为您在查询中错过了“order by”，试试这个:

protected  function getJobs(){
        $jobs = Job::Join('customer','jobs.customerid','=','customer.id')
            ->select(array('jobs.id','customer.firstname','customer.lastname','jobs.jobstatus','jobs.trialdate','jobs.deliverydate'))
            ->orderBy('customer.lastname')->get();  
        return Datatables::of($jobs)
            ->addColumn('action', '<a class="btn btn-default btn-xs" data-toggle="tooltip" data-placement="top" title="Edit" href="{{ URL::to(\'updatejob/\'.$id) }}"><i class="fa fa-pencil"></i></a>')
        ->make();

}
