Для удаления оъектов по условию реализуем метод deleteAll
exports.deleteAll = (req, res) => { Tutorial.destroy({ where: {}, truncate: false }) .then(nums => { res.send({ message: `${nums} Tutorials were deleted successfully!` }); }) .catch(err => { res.status(500).send({ message: err.message || "Some error occurred while removing all tutorials." }); }); };
