Laravel: eloquent 关系创建多

Question

i have a ParentItem model

$parentItem = ParentItem::get()->first();

I have this array

$items = array(
 array(
  'title' => 'test1',
  'desc' => 'test1'
 ),
 array(
  'title' => 'test2',
  'desc' => 'test2'
 )
);

i want to add it as a has many relationship. so i can do:

foreach($items as $item) {
 $parentItem->items()->create($item)
}

is there any way way to create all at once..? something like:

$parentItem->items()->createMany($items);

Answer 1

You can tryout two path.

Using saveMany method:

$parentItem = ParentItem::first();
$items = array(
    new Item(['title' => 'test1','desc' => 'test1']),
    new Item(['title' => 'test2','desc' => 'test2'])
);
$parentItem->items()->saveMany($items)

For further info you can read here.

https://laravel.com/docs/5.1/eloquent-relationships#inserting-related-models

Using insert method:

$parentItem = ParentItem::first();
$items = array(
    array('title' => 'test1','desc' => 'test1','parent_item_id' => $parentItem->id),
    array('title' => 'test2','desc' => 'test2','parent_item_id' => $parentItem->id)
);
Item::insert($items);

Remember in insert created_at and updated_at won't be inserted automatically, you have to provide them in the array if you have them in your table. For further info you can read here.

Answer 2

As of right now, you may use the createMany Eloquent method to achieve this.
