Phalcon framework - add related models

Question

I have an object, Request , with a has-many relationship to RequestItem (aliased to items ). So Request->items is a Simple Resultset.

I see in the docs there is a way to update related records with update() , and delete related records with delete() . Is there any way to add related records in a similar fashion? I tried just $this->items[] = $Item, but got a "Cursor is an immutable ArrayAccess object" error.

I basically want to simply add a new related record to Request, and have Request->items reflect the addition. I was unable to find anything in the docs, which surprised me actually.

This question is over a year old at this point. New answers are not necessary or helpful

Answer 1

When you have a one to many relationship and you want add new items you have to set the array with the objects that do you want to add. example:

$Request = new Request();
// ... sets the attributes for Request object
$item1 = new RequestItem();
$item1->attr1 = $value1; 
// ... add the attributes you want
$item2 = new RequestItem();
$item2->attr1 = $value2;
// ... and so on
$items = array($item1, $item2 /*, ... all that you need */);
$Request->items = $items;
if ($Request->save()) {
    echo 'Good';
}

Answer 2

you must initialize belongsTo(Request) in the RequestItem model. when you add it, you create

$newItem = new RequestItem();
$newItem->setRequest($request);
$newItem->create();

then you will be able to get all items using $request->getItems();

Answer 3

please show me your db table structure with full realation's.

and you most use method in this page: http://docs.phalconphp.com/pt/latest/reference/models.html#defining-relationships

Answer 4

class Request extends \Phalcon\MVC\Model
{
  public function initialize()
  {
    $this->hasMany('id', 'RequestItem', 'request_id');
  }
}

$this->hasMany(' foreign key of main model ', ' related model name ', ' foreign key for related ');

class RequestItem extends \Phalcon\MVC\Model
{
  public function initialize()
  {
    $this->belongsTo('request_id', 'Request', 'id');
  }
}

$this->hasMany(' foreign key for related ', ' main model name ', ' foreign key of main model ');

As long as it's all set properly you can perform creation of related records like this:

class RequestsController extends \Phalcon\MVC\Controller
{
  public function createItemsAction($RequestId)
  {
    $Request = Request::findFirst($RequestId);
    $RequestItem = new RequestItem();
    $RequestItem->Request = $Request;
    $RequestItem->otherproperties = .....
  }
}

Hope that is close to what you needed
