Question

我正在使用 laravel 和数据表版本的详细信息：

| Laravel 5.5 |
| Yajra/datatables 8* |

当我尝试查询数据

时，我总是遇到此错误

"message": "Method where does not exist.",
"exception": "BadMethodCallException",

我的代码在下面

public function getExpensesHistory(Request $request){


        $data = Expenses::with(['expenses' => function ($query) {
            $query->select('id', 'type_name');
        },'user' => function ($query) {
            $query->select('id', 'name');
        }])->orderBy('exp_date','desc')->get(); 

        $datatables=DataTables::of($data);

        $from_date = date('Y-m-d',strtotime($datatables->request->get('from_date')));
        $end_date = date('Y-m-d',strtotime($datatables->request->get('end_date')));

        if ($end_date  and $from_date) {
            $datatables->where('exp_date','<=',$end_date)->where('exp_date','>=',$from_date);
        }

        return $datatables->make(true);

    }

您的查询应该像

一样

$query = Expenses::query();
$query->with(['expenses' => function ($query) {
    $query->select('id', 'type_name');
},'user' => function ($query) {
    $query->select('id', 'name');
}]);

$from_date = date('Y-m-d',strtotime($request->from_date));
$end_date = date('Y-m-d',strtotime($request->end_date));

if ($end_date and $from_date) {
    $query->where(function($q) use ($from_date, $end_date){
        $q->where('exp_date','>=',$from_date);
        $q->where('exp_date','<=',$end_date);
    });
}

$data = $query->orderBy('exp_date','desc')->get();

在这里，我在变量中进行查询，并在该对象上执行所有操作

在Yajra Datatable中出错
