Question

我是laravel的新手但我真的很喜欢它。现在我和Eloquent玩了一点，然后提出了一个问题：

我有两个地址的Cusomers（BillingAdress和DeliveryAddress）

Cusomers-Fields：ID，Firstname，Lastname，BillingAddress，DeliveryAddress 地址 - 字段：ID，地址，邮编，城市，国家

现在我想创建客户，在我创建他之后，我想给他分配他的地址。

客户模式：

class Customer extends Model
{
    public function deliveryAddress() {
        return $this->hasOne("App\Address");
    }

    public function billingAddress() {
        return $this->hasOne("App\Address");
    }
}

地址型号：

 class Address extends Model
    {
        public function customer() {
            return $this->belongsTo("App\Customer");
        }
    }

控制器：

$c = new Customer;
$c->Firstname = "John";
$c->Lastname = "Doe";
$c->save();

$billingAddress = new Address;
$billingAddress->address = "Exampleroad 3";
$billingAddress->zip = 11111;
$billingAddress->city = "Examplecity";

$deliveryAddress = new Address;
$deliveryAddress->address = "Doestreed 21";
$deliveryAddress->zip = "44444";
$deliveryAddress->city = "Doedown";

$c->billingAddress()->save($billingAddress);
$c->deliveryAddress()->save($deliveryAddress);

但是现在地址表中的cusomer_id被保存了，但是cusomer表中的deliveryAddress和billingAddress是空的。

您应该设置外键和本地键，以便Laravel知道您指的是哪些字段。

class Customer extends Model
{
    public function deliveryAddress() {
        return $this->hasOne("App\Address", "id", "deliveryAddress");
    }

    public function billingAddress() {
        return $this->hasOne("App\Address", "id", "billingAddress");
    }
}
