SequelizeDatabaseError: could not serialize access due to concurrent update
In Mocha test beforeEach hook, I am trying to destroy all table records.
import { db } from '../src/db/models';
export const truncateTable = () => {
const promises = Object.keys(db).map(key => {
if (key !== 'Sequelize' && key !== 'sequelize') {
console.log(key);
return db[key].destroy({ where: {} });
}
});
return Promise.all(promises);
};
Then in the test, I am doing this:
describe.only('application mutations', () => {
beforeEach(() => truncateTable());
...
The error I am getting:
SequelizeDatabaseError: could not serialize access due to concurrent
update

TL/DR: in your tests, if you want a quick way to delete models and reset your DB, use sync.
describe.only('application mutations', () => {
beforeEach(async () => {
await db.sync({force: true})
});
}
If you want to individually destroy your models, you must properly await for your promise to finish before initiating a new one. Currently, your promises are being initiated all at once, hence the Sequelize error.
export const truncateTable = async () => {
const promises = Object.keys(db).map(key => {
if (key !== 'Sequelize' && key !== 'sequelize') {
await db[key].destroy({ where: {} });
}
});
};
// in your test file
describe.only('application mutations', () => {
beforeEach(async () => {
await truncateTable();
});
})
