Symfony Generator, Doctrine, and M: N Forms

Question

I have a basic setup of M: N with three tables: candidate, position and candidate.

Here is a screenshot of ERD from MySQL Workbench

Now, moving on from this, let's talk about forms. In the standard symfony generator world, you will have a separate CRUD interface for all three of these tables. However, I do not want to have a CRUD interface for candidate_position.

I want a field with several choices (select a list, an array of flags, whatever) to create CandidatePosition entries as part of the candidate’s actions for actions to create and edit the candidate’s interface.

Answer 2

Symfony - 1.4.11, .

, doSave() Form :

protected function doSave($con = null)
{
    $existing = $this->object->Position->getPrimaryKeys();
    $values = $this->getValue('candidate_positions');

    $unlink = array_diff($existing, $values);
    $this->object->unlink('Position', array_values($unlink));

    $link = array_diff($values, $existing);
    $this->object->link('Position', array_values($link));

    parent::doSave($con);
}

, , :

public function updateDefaultsFromObject()
{
    parent::updateDefaultsFromObject();

    if (isset($this->widgetSchema['candidate_positions']))
    {
        $this->setDefault('candidate_positions', $this->object->Position->getPrimaryKeys());
    }
}

.

UPDATE

, , 1.4.11 , , , table 'candidPosition' :

  relations:
    Candidate:
      class: Candidate
      local: candidate_id
      foreign: id
      foreignAlias: Candidates
    Position:
