模型定义
class User
{
public function customer()
{
return $this->hasOne(‘Customer‘);
}
}
class Customer
{
public function user()
{
return $this->belongsTo(‘User‘);
}
}
需要注意的是 associate 方法是 BelongsTo 类才有，所以正确的调用方法如下：
$user = new User($data); $customer = new Customer($customerData); $customer->user()->associate($user); $customer->save();
与此相反的方法是 disassociate 方法：取消两个模型之间的 belongsTo 关联
$customer->user()->disassociate(); $customer->save()
此方法需要注意的是，disassociate 并不会删除记录，只是更新关联的字段为 null
附(通过关联的模型保存)：
$user = new User($data); $user->save(); $customer = new Customer($customerData); $user->customer()->save($customer);
