Symfony: embedRelation() controlling options for nesting multiple levels of relations

Question

Hey all,

I'm trying to set some conditional statements for nested embedRelation() instances, and can't find a way to get any kind of option through to the second embedRelation.

I've got a "Measure->Page->Question" table relationship, and I'd like to be able to choose whether or not to display the Question table. For example, say I have two "success" pages, page1Success.php and page2Success.php. On page1, I'd like to display "Measure->Page->Question", and on page2, I'd like to display "Measure->Page", but I need a way to pass an "option" to the PageForm.class.php file to make that kind of decision. My actions.class.php file has something like this:

// actions.class.php
$this->form = new measureForm($measure, array('option'=>$option));

to pass an option to the "Page", but passing that option through "Page" into "Question" doesn't work.

My measureForm.class.php file has an embedRelation in it that is dependent on the "option":

// measureForm.class.php
if ($this->getOption('option') == "page_1") {
    $this->embedRelation('Page');
}

and this is what i'd like to do in my pageForm.class.php file:

// pageForm.class.php
if ($this->getOption('option') == "page_1") { // Or != "page_2", or whatever
    $this->embedRelation('Question');
}

I can't seem to find a way to do this. Any ideas?

Is there a preferred Symfony way of doing this type of operation, perhaps without embedRelation?

Thanks, -Trevor

I've decided to use embedForm() instead. It ended up being some Doctrine_Query::create()->select()... and Doctrine::getTable commands followed by some foreach loops and embedForm statements. So much for embedRelation!
