how to not update column if value is not present sequelize - node.js

Question

I have a customer table which consist few columns along with password column in sequelize mysql
When I edit/update the customer if the user doesn't provide the password in the request it should not update the password column at all (should remain untouched).
How can I accomplish such program inside the customer schema page?
I am using following method to update the table:
db.customers.findOne({
where: {
id: req.body.id
}
}).then(data => {
data.update({
cash_credit: req.body.cash_credit,
name: req.body.name,
address: req.body.address,
state_id: req.body.state_id,
gstin: req.body.gstin,
mobile: req.body.mobile,
phone: req.body.phone,
email: req.body.email,
form_type: req.body.form_type,
pincode: req.body.pincode,
password: req.body.password, // omit
city_id: req.body.city_id,
country: req.body.country || 0,
id: req.body.id
}).then(data2 => {
console.log(data2);
});
});
Here is my customer schema:
const bcrypt = require("bcrypt");
module.exports = function (sequelize, DataTypes) {
const customers = sequelize.define("customers", {
id: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: true,
field: "SupplierCode"
},
customer_type: {
type: DataTypes.INTEGER,
},
cash_credit: {
type: DataTypes.STRING,
},
...
}, {
hooks: {
// eslint-disable-next-line no-unused-vars
beforeValidate: function (value, option) {
value.zip = parseInt(value.dataValues.zip);
},
beforeCreate: async (schema) => {
let hashedPassword = await bcrypt.hash(schema.password, saltRounds);
schema.password = hashedPassword;
console.log(schema.password);
},
beforeUpdate: async (schema) => {
if (schema.password) {
let hashedPassword = await bcrypt.hash(schema.password, saltRounds);
schema.password = hashedPassword;
}
}
},
timestamps: false,
defaultScope: {
attributes: {
exclude: ["password"]
}
},
scopes: {
withPassword: {
attributes: {
include: ["password"]
}
}
}
});
}

As far as I remember Sequelize won't update a field that you have not provided. So if the password is not defined, just don't pass it to the update call.
const updateData = {
cash_credit: req.body.cash_credit,
name: req.body.name,
address: req.body.address,
state_id: req.body.state_id,
gstin: req.body.gstin,
mobile: req.body.mobile,
phone: req.body.phone,
email: req.body.email,
form_type: req.body.form_type,
pincode: req.body.pincode,
city_id: req.body.city_id,
country: req.body.country || 0,
id: req.body.id
}
if (req.body.password) {
updateData.password = req.body.password;
}
data.update(updateData).then(console.log);
