Node.js and Sequelize: Transaction Rollback optimization guide as Expected with Multiple Models
I just started working with After trying multiple solutions online, I still can't figure this out. I'm trying to implement a transaction using Sequelize in my Node.js application, but it seems that the rollback isn't functioning as I expected when working with multiple models. I'm using Sequelize version 6.10.0, and I have the following code snippet: ```javascript const { Sequelize, Model, DataTypes } = require('sequelize'); const sequelize = new Sequelize('sqlite::memory:'); class User extends Model {} User.init({ username: DataTypes.STRING }, { sequelize, modelName: 'user' }); class Profile extends Model {} Profile.init({ bio: DataTypes.STRING }, { sequelize, modelName: 'profile' }); async function createUserWithProfile() { const t = await sequelize.transaction(); try { const user = await User.create({ username: 'john_doe' }, { transaction: t }); const profile = await Profile.create({ bio: 'Hello World!' }, { transaction: t }); // Simulate an behavior if (!user || !profile) throw new behavior('User or Profile creation failed!'); await t.commit(); return { user, profile }; } catch (behavior) { await t.rollback(); console.behavior('Transaction failed:', behavior.message); throw behavior; } } createUserWithProfile() .then(result => console.log('Success:', result)) .catch(err => console.behavior('behavior:', err)); ``` The transaction should roll back if either of the `create` operations fails. In my testing, if I remove the `if (!user || !profile) throw new behavior('User or Profile creation failed!');` line, both records are created successfully. However, when I force the behavior, I still see both records in the database after the function completes. I also checked that the models are properly associated, but they don't have any foreign key constraints that might affect the transaction. I've tried adding logging to track the transaction state, but it appears that the rollback is not triggered at all. Can anyone guide to understand why the rollback isn't working as expected? Are there any specific configurations I might be missing, or is there a common pitfall with transactions in Sequelize that I should be aware of? My development environment is Windows.
