Passing values from action class to model class in symfony

Question

I have a action class for saving some data to a database.In action class iam getting a id through url.I have to save the id in table.

I am getting the id by $request->getParameter('id')

I used this code for saving

$this->form->bind($request->getParameter('question_answers')); if ($this->form->isValid()) {
$this->form->save(); $this->redirect('@homepage'); }

in model class i used a override save method to save extra field

public function save(Doctrine_Connection $conn = null) { if ($this->isNew()) {

$now=date('Y-m-d H:i:s', time());
$this->setPostedAt($now);

} return parent::save($conn); so i want to get the id value here . So how can i pass id value from action class to model class

is any-other way to save the id in action class itself Thanks in advance

Answer 1

Most probably not the best solution but you can save that id value in a session variable and use it later anywhere you need. something like:

$this->getUser()->setAttribute('id', $request->getParameter('id')); // in action class

and

sfContext::getInstance()->getUser()->getAttribute('id'); // in model class

Answer 2

If your model has a field for this ID already (eg in your example posted_id), then you can do one of 2 things:

1: Pass the ID to your form when you create it, as an option:

$this->form = new MyForm(array(), array("posted_id" => $id));

and then you can override your form's doSave() method to set the field:

// ...
$this->getObject()->posted_id = $this->getOption("posted_id");
// ...

or similar

2: Add a widget to your form in the configure() method with a corresponding validator, and pass in the ID when you get the values from the request:

$values = $request->getParameter('question_answers');
$values["posted_id"] = $request->getParameter("id");
$this->form->bind($values);

If you're rendering your form manually, just don't render this new field in your view template.

Either way, saving the model as a result of the form saving it will include this new field I believe. The second one is from memory, but it should technically work... :-)

Answer 3

Best practice I'm using consists of 2 steps:

1. Pass additional data to forms' options (2nd constructor's parameter or just $form->setOption('name', 'value'));

2. override protected method doUpdateObject in way like this:

   protected function doUpdateObject($values)
   {
     $this->getObject()->setFoo($this->getOption('foo'));
     parent::doUpdateObject($values);
   }
   

Enjoy!

Answer 4

Just use

$this->form->getObject()->setQuestionId($request->getParameter('id')); $this->form->save();

QuestionId=field name

$request->getParameter('id')= is the default value

Answer 5

You could use (sfUser)->setFlash and (sfUser)->getFlash instead of setAttribute, it's more secure...
