有这么一组数据
一个学生表users 和 学生成绩表 grades 两个表关联
在方法里面是这样的
public function index(){ $result = user::where('is_admin', 0); $users = $result->get(); $count = $result->count(); return view('admin.list', compact('count', 'users'));}

视图循环是这样的
@foreach ($users as $user) {{$user->id}} {{$user->name}} {{$user->grade->math}} {{$user->grade->english}} {{$user->grade->c}} {{$user->grade->sport}} {{$user->grade->think}} {{$user->grade->soft}}
@endforeach

得到的结果是 报错 trying to get property of non-object (view:
$user->grade->math

是找不到的 怎么做关联一起呢
