示例1: exists
public function exists($conditions, $checkStatus = false)
{
if (!is_array($conditions) && is_numeric($conditions)) {
$conditions = ['id' => $conditions];
}
if ($checkStatus && !empty($this->_activeStatuses)) {
$conditions['status IN '] = $this->_activeStatuses;
}
return parent::exists($conditions);
}示例2: existsById
/**
* 2.x shim for exists() and primary key.
*
* @param int $id
* @return bool
*/
public function existsById($id)
{
$conditions = [$this->primaryKey() => $id];
return parent::exists($conditions);
}示例3: generateSlug
/**
* Slug method
*
* For the given string, generate a slug. The replacements used are based on the mode setting, If tidy is false
* (only possible if directly called - primarily for tracing and testing) separators will not be cleaned up
* and so slugs like "-----as---df-----" are possible, which by default would otherwise be returned as "as-df".
* If the mode is "id" and the first charcter of the regex-ed slug is numeric, it will be prefixed with an x.
* If unique is set to true, check for a unique slug and if unavailable suffix the slug with -1, -2, -3 etc.
* until a unique slug is found
*
* @param string $value
* @param \Cake\ORM\Entity|null $entity
* @return string A slug
