Laravel一对多关系插入数组

Question

I get from my form page an array of values in the form of:

"managed_cluster" => array:2 [▼
    0 => "Benelux"
    1 => "Germany & Austria"
]

I have 2 models: User

public function clusters()
{
    return $this->hasMany('App\Cluster');
}

So I have the table users with id and name column and I have the table clusters with id, user_id and cluster_name column. The link between the 2 tables is the users.id and clusters.user_id

I know that if I use App\\User::find(1)->clusters()->saveMany(x) then x needs to be a set of objects but I was wondering how I could do that straight with the array? Or do I need to do a foreach on the array and then save the clusters one by one (from what I got from the form)?

Thanks.

Answer 1

Try to use the function createMany() which accepts an array as an attribute, for example:

$user = App\User::find(1);

$user->clusters()->createMany([
    [
        'cluster_name' => 'cluster1',
    ],
    [
        'cluster_name' => 'cluster2',
    ],
]);
