php - 在 laravel 中更新表及其相关模型？

Question

我有客户表和客户地址信息表。在更新下面给出的 client.my 模型类时，我需要更新这两个表，

        class Client extends Model {
             public function addressInfo() {
              return $this->hasOne('App\Model\ClientAddressInfo');
             }
        }

      class ClientAddressInfo extends Model {    
            protected $table = 'client_address_info';    
              public function client() {
               return $this->belongsTo('App\Model\Client');
            }
     }

我的更新 Controller 如下。

$client = Client::findOrFail($id);
$client->name = rand(0, 1222222);
$address = ClientAddressInfo::where('client_id', '=', $id)->get();
$address->street = "new street";
$address->save();

但它不起作用，能否请您解释更新模型及其相关模型的最佳实践。

你可以更简单地做到这一点:

$client = Client::findOrFail($id);
$client->name = rand(0, 1222222);
$client->addressInfo->street = 'new street';
$client->addressInfo->save();
$client->save();

除了在两个模型上都调用 save()，您还可以使用 push() 来保存模型及其所有相关模型:

$client = Client::findOrFail($id);
$client->name = rand(0, 1222222);
$client->addressInfo->street = 'new street';
$client->push(); // save client and addressInfo
