Sequelize Update with Object - node.js

Question

I have a code using sequelize to update one record and then return this updated record:
const companyId = req.params.id
const companyNewDetail = req.body
console.log("companyNewDetail", companyNewDetail)
await Company.update(companyNewDetail, {
where: {
companyId,
},
})
const company = await Company.findOne({
where: {
companyId,
},
})
res.status(200).send({ status: 0, data: company })
It is working but I have to seperate into two query statements. Is there a way I can mix them together? I want to pass the update parameter with a object rather than destructuring the object and assign to the instance one by one.

The returning option of Model.update still only supports PostgreSQL for sequelize v6.
For example:
import { sequelize } from '../../db';
import { Model, DataTypes, Sequelize } from 'sequelize';
// const sequelize = new Sequelize('sqlite::memory:');
class Company extends Model {}
Company.init(
{
companyId: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false,
},
name: DataTypes.STRING,
},
{ sequelize, tableName: 'companies' },
);
(async function test() {
try {
await sequelize.sync({ force: true });
// seed
await Company.create({ name: 'google' });
// test
const companyId = 1;
const companyNewDetail = { name: 'reddit' };
const result = await Company.update(companyNewDetail, {
where: {
companyId,
},
returning: true,
});
console.log(result);
} catch (error) {
console.log(error);
} finally {
await sequelize.close();
}
})();
If you use postgres dialect, you will get the following result:
Executing (default): DROP TABLE IF EXISTS "companies" CASCADE;
Executing (default): DROP TABLE IF EXISTS "companies" CASCADE;
Executing (default): CREATE TABLE IF NOT EXISTS "companies" ("companyId" SERIAL , "name" VARCHAR(255), PRIMARY KEY ("companyId"));
Executing (default): SELECT i.relname AS name, ix.indisprimary AS primary, ix.indisunique AS unique, ix.indkey AS indkey, array_agg(a.attnum) as column_indexes, array_agg(a.attname) AS column_names, pg_get_indexdef(ix.indexrelid) AS definition FROM pg_class t, pg_class i, pg_index ix, pg_attribute a WHERE t.oid = ix.indrelid AND i.oid = ix.indexrelid AND a.attrelid = t.oid AND t.relkind = 'r' and t.relname = 'companies' GROUP BY i.relname, ix.indexrelid, ix.indisprimary, ix.indisunique, ix.indkey ORDER BY i.relname;
Executing (default): INSERT INTO "companies" ("companyId","name") VALUES (DEFAULT,$1) RETURNING *;
Executing (default): UPDATE "companies" SET "name"=$1 WHERE "companyId" = $2 RETURNING *
[
1,
[
Company {
dataValues: [Object],
_previousDataValues: [Object],
_changed: {},
_modelOptions: [Object],
_options: [Object],
isNewRecord: false
}
]
]
The first element of the result array is the number of affected rows for the updating operation. The second element is the sequelize model instances of updated rows.
For sqlite3, you will get:
Executing (default): DROP TABLE IF EXISTS `companies`;
Executing (default): DROP TABLE IF EXISTS `companies`;
Executing (default): CREATE TABLE IF NOT EXISTS `companies` (`companyId` INTEGER PRIMARY KEY AUTOINCREMENT, `name` VARCHAR(255), `createdAt` DATETIME NOT NULL, `updatedAt` DATETIME NOT NULL);
Executing (default): PRAGMA INDEX_LIST(`companies`)
Executing (default): INSERT INTO `companies` (`companyId`,`name`,`createdAt`,`updatedAt`) VALUES (NULL,$1,$2,$3);
Executing (default): UPDATE `companies` SET `name`=$1,`updatedAt`=$2 WHERE `companyId` = $3
[ undefined, 1 ]
So, you need to do an additional query for other databases after updating the rows in the table.
