I have a basic M:N setup with three tables: candidate, position, and candidate_position.
Here's a screenshot of the ERD from MySQL Workbench
Now, moving on from that let's talk about forms. In the default world of symfony generator, you'd have a separate CRUD interface for all three of these tables. However, I don't want to have a CRUD interface for candidate_position
.
What I want, is for the create and edit actions of the Candidate interface to contain a multi-choice field (select list, checkbox array, whatever) that would create the CandidatePosition records as part of the Candidate actions.
On to the code
config/doctrine/schema.yml (Note: the is not the entire schema.yml, but only the tables discussed here)

lib/form/doctrine/candidateForm.class.php
class candidateForm extends BasecandidateForm
{
public function configure()
{
unset( $this['created_at'] );
$this->widgetSchema['candidate_positions'] = new sfWidgetFormDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'renderer_class' => 'sfWidgetFormSelectCheckbox' )
);
$this->validatorSchema['candidate_positions'] = new sfValidatorDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'min' => 1 )
);
}
}
This all works, except when it comes to actually saving the data. This is the point where I get stuck.
I clearly need to do something to create/edit/delete the CandidatePosition records, but I'm not sure where to start working. In candidateActions
? Override Basecandidate::save()
?
Let me know if there's any other data you might need to see.
