CakePHP - delete cascade not working

Question

In CakePHP I have a model Type and SpecificType.

SpecificType belongTo a Type. (type_id field)

When I delete an entry of SpecificType, how can I also delet

Answer 1

I had the same problem in a situation where I did not want to follow the Cake model key convention.

I set the SpecificType model's belongsTo relationship to Type like so:

public $belongsTo = array(
  'Type' => array(
    'className' => 'Type',
    'foreignKey' => 'type_id',
    'conditions' => '',
    'fields' => '',
    'order' => '',
  ),
);

Then to get cascading delete to work, I added the following to the SpecificType model:

public function beforeDelete($cascade) {
  // Make sure the parent method runs.
  $continue = parent::beforeDelete($cascade);

  if ($continue) {
    // Delete the Type if there is one.
    $typeId = $this->field('type_id');
    if (!empty($typeId)) {
      $continue = $this->Type->delete($typeId);
    }
  }

  return $continue;
}

I hope that helps someone who has the same problem you had as I'm sure you're not still waiting for an answer.
