Laravel 有关系 - 找不到列

Question

我使用这个查询：

$clients = Client::with("types", "results")->where(function ($query) use ($issued, $mode, $request) {

      if (($request->get("filter"))) {
         $query->where('issued', $issued);
      }
    }

与results的关系是：

public function results()
    {
        return $this->hasOne('App\ResultTest', 'client_id', 'unique_code');
    }

Table ResultTest' 有 client_id 字段和 issued。它与当前 table 合并为：

Client.uqique_code = ResultTest.clients.

现在tableResultTest是空的。

它 returns 我一个错误：

Unknown column 'issued' in 'where clause' (SQL: select count(*) as aggregate from `clients` where (`issued` = 1))

我试过这种方法，下面的答案中推荐了这种方法：

$clients->with(["results" => function($query) use ($issued, $request, $mode) {
            $query->where('issues', $issued);

            if (($request->get("mode"))) {
                $query->whereIn('mode', $mode);
            }

        }])->orderBy('created_at', 'desc')->paginate();

它给出了同样的错误：

 Unknown column 'issues' in 'where clause' (SQL: select * from `result_test` where `result_test`.`client_id` in (342074, 160374, 596433) and `issues` = 0)

经过长时间的交谈，我们找到了以下解决方案：

if($request->has('filter') || $request->has('mode')) { 
    $builder->whereHas('results', function ($query) use ($request) { 

        if (($request->has("filter"))) { 
            $query->where('issued', $request->get('filter')); 
        } 

        if (($request->has("mode"))) { 
            $query->whereIn('mode', $request->get('mode')); 
        } 
    }); 
}
