Laravel bulk insert with one-to-one relation

Question

I know that I can insert multiple records in laravel with:

$data = [
    ['name' => '...', 'age' => ...],
    ['name' => '...', 'age' => ...],
    ['name' => '...', 'age' => ...],
];
Model::insert($data);

But is is possible to do a bulk insert that also has a one-to-one relation? So that I insert data into two databases at the same time?

Something like:

$data = [ ['name' => '...', 'age' => ...], ['name' => '...', 'age' => ...], ['name' => '...', 'age' => ...], ];

Model::withSecondTable()->insert($data);

Answer 1

Yes it is possible. For example:

###User Model:

public function item()
{
  return $this->belongsTo('Item');
}

###Item Model:

public function users()
{
  return $this->hasMany('User');
}

To save a User from the Item perspective, you do this:

$item->users()->save($user);

To associate an item with a user, you do this:

$user->item()->associate($item);
$user->save();
