How to return an array of IDs in Laravel?

Question

Laravel

Tell me please. How can I return an array of IDs in the model? I have a Ticket model. It has a link to messages:

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

For the API, I have added the messagesIds method which should return an array of IDs.. How can I do this? Heard that ORM should return an object, but I need an array.

Answer 1

$message->tikets->lists('id')->toArray()
It was like that, as far as I remember.

Answer 2

Try like this:

public function messagesIds()
{
    $this->messages->pluck('id')->toArray();
}

Answer 3

It is necessary to specify the with("messages") method when calling the model.
But the array count:
In the model itself, you can specify:

protected $casts = [
        'options' => 'array',
    ];

Answer 4

return $this->hasMany('App\Message')->select(['id', 'message_id']);
