Hello,
I have some trouble with a project I'm building with symfony 1.4 &
doctrine 1.2. I have a Page and a Tag model. They're bound through a
PageTag refClass in a m2m relationship.
Since the tag class is also bound to several other models, I'm trying
to keep track of a tag's associations into the tags' table. I added a
column 'associations_count' to the Tag schema, and added two methods
to the model to increment or decrement this property. So far so good.
Incrementing the counter when a new PageTag object is created works
like a charm. I override the preInsert method, and it works.
But decrementing does not work that easily. My first idea was to
override the preDelete method:
class PageTag extends BasePageTag
{
...
public function preDelete($event)
{
$this->Tag->decrement()->save();
return parent::preDelete($event);
}
}
This code is not executed when you break the link between a Page and a
Tag in the generated admin. I've also tried to override the delete
method, with the same (lack of) result. If I write this :
class PageTag extends BasePageTag
{
...
public function delete(Doctrine_Connection $conn = null)
{
die('foo');
$this->Tag->decrement()->save();
return parent::delete($conn);
}
}
The corresponding row is removed from the page_tag table. Doctrine
does not hydrate the records to delete them.
My question is : how can I hook in the record's removal process ?
Thank you for your help ;)
