KnexJS Transaction
How can I execute this transaction? My problem is the correct use of for
instruction.
app.db.transaction(function (trx)
app.db('sales_record_products').transacting(trx).insert(products)
.then(_ =>
for (let i = 0; i < stockProducts.ids.length; i++)
app.db('products').transacting(trx).where('id',stockProducts.ids[i]).update(quantity: stockProducts.results[i])
.then(_ =>
)
)
.then(trx.commit)
.catch(trx.rollback)
)
.then(_ => res.status(200).json(success: true))
.catch(err => res.status(500).send(err))
node.js knex.js

Why not using something like
// Start a database transaction
return app.db.transaction(function (trx)
// Insert products
return trx.insert(products)
.then(function (newIds)
// Product inserted, you have the new database id in newIds
// Update all product individually but sequentially
return Promise.mapSeries(stockProducts, function (sp)
// Update a single product
return trx
.table('products')
.where('id', stockProducts.ids[i])
.update( quantity: stockProducts.results[i] );
);
);
);
error: UnhandledPromiseRejectionWarning: Error: ER_PARSE_ERROR: You have an error in your SQL syntax; I'm using knexjs
