带参数的热切加载 - laravel

I have Banks表和单独的表services

$bank = Banks::find(1);
echo $bank->service(1); // print bank with that service (serviceId 1)

可以通过 service_id =1 急切加载所有银行..有点像

Bank::with('service(1)')->get();

先感谢您

当然！这with方法接受一个闭包来过滤急切加载。

Bank::with(array('service' => function($query){
    $query->where('id', 1);
}))->get();
