   * @param bool $runValidation whether to perform validation (calling [[validate()]])
   * before saving the record. Defaults to `true`. If the validation fails, the record
   * will not be saved to the database and this method will return `false`.
   * @param array $attributeNames list of attribute names that need to be saved. Defaults to null,
   * meaning all attributes that are loaded from DB will be saved.
   * @return bool whether the saving succeeded (i.e. no validation errors occurred).
