First, you have to create relation in your Person model
首先，您必须在 Person 模型中创建关系
class Person extends Model
{
protected $fillable = ['firstname', 'lastname'];
public function employee()
{
return $this->hasOne('App\Employee');
}
}
After that in your controller you can do:
之后，在您的控制器中，您可以执行以下操作：
$person = Person::create($personData);
$person->employee()->create($employeeData);
As @Alexey Mezeninmentioned you can use:
正如@Alexey Mezenin提到的，您可以使用：
$person = Person::create(request()->all());
$person->employee()->create(request()->all());
Also inverse would be:
反之亦然：
class Employee extends Model
{
protected $fillable = ['position'];
public function person()
{
return $this->belongsTo('App\Person');
}
}

You still need to create person first, so if you're looking for readable and consize solution, you can do is this:
您仍然需要先创建 person，所以如果您正在寻找可读和精简的解决方案，您可以这样做：
$data = [
'firstname' => 'Hyman',
'lastname' => 'London',
'position' => 'writer'
];
$person = Person::create($data);
$person->employee()->create($data);
