beforeBulkDestroy not finding model property to change - node.js

Question

I am trying to use the beforeBulkDestory Sequelize hook on a user delete that will switch the deleted column boolean to true prior to updating the record to add a timestamp for deleted_at. However, when I console.log the function parameter it provides a list of options and not the model object that I can update for the record of focus. Am I approaching this the wrong way? Is this something that should be set using model instances?
API Call:
import db from '../../../models/index';
const User = db.users;
export default (req, res) => {
const {
query: { id },
} = req
console.log(User)
if (req.method === 'DELETE') {
User.destroy({
where: {
id: id
}
}).then(data => {
res.json({
message: 'Account successfully deleted!'
})
})
} else {
const GET = User.findOne({
where: {
id: id
}
});
GET.then(data => {
res.json(data)
})
}
}
Parameter Values (beforeBulkDestroy, afterBulkDestroy):
beforeBulkDestroy
{

hooks: true,

}

hooks: true,
individualHooks: true,
force: false,
cascade: false,
restartIdentity: false,
type: 'BULKUPDATE',
model: users
}
Model (users.js):
'use strict';
const Sequelize = require('sequelize');
const { Model } = require('sequelize');
const bcrypt = require("bcrypt");
module.exports = (sequelize, DataTypes) => {
class users extends Model {
/**

* The `models/index` file will call this method automatically.
*/
static associate(models) {

Answer 1

the before/after bulkDestroy hooks only receive the options, not the instances. One way you could do this is defining a before/after Destroy hook:
hooks: {
beforeDestroy: (user, { transaction }) => {
user.update({ deleted: true }, { transaction });
}
}
and calling User.destroy with the individualHooks option:
User.destroy({ where: { id: id }, individualHooks: true });
Be aware that this will load all selected models into memory.

Note: In your case, since you're only deleting one record by id, it would be better to just user = User.findByPk(id) then user.destroy(). This would always invoke the hooks and it also makes sure the record you want to delete actually exists.
Note 2: Not sure why you need a deleted column, you could just use deletedAt and coerce it into a boolean (with a virtual field if you want to get fancy).
