Transactions - commit manual managed transaction

What you are doing?

I want to create a transaction and control which queries it will run. I want to do that using node 7.8.0 and async/await syntax. Here is a sample of the code I’m trying to run -

const transaction = await db.sequelize.transaction();
await db.User.create({ username: 'roy' }, { transaction });
await transaction.commit();

What do you expect to happen?

The transaction to complete

What is actually happening?

I get this error-

commit has been called on this transaction(3b1ab60a-172c-4795-9ace-b89b855c92ce), you can no longer use it. (The rejected query is attached as the 'sql' property of this error)

btw, if I run my code without using transactions it works. I just want to understand how to use transactions the right way using async/await.

Thanks.

Dialect: postgres Sequelize version: 4.0.0-2

In my case the problem was a stupid mistake - missing await when calling the save

await entity.save({ transaction });

This feature is desperately needed for code quality purposes and to ease the pain of testing with Sequelize at the moment.

@roytz, from everything I could find, the prescribed way to use transactions is to perform all of the operations you need to do from within the context of the next handler in the promise chain like so:

await db.sequelize.transaction().then(async transaction => {
    await db.User.create({ username: 'roy' }, { transaction })
})

Which I find fairly annoying to deal with.
