knex.js

I have got a local development environment working for Node/PostgreSQL/Knex in the sense that I can post to a development database on my machine using an API. I am now trying to create tests for this functionality but am getting an error. Here's my config: //knexfile.js module.exports = { development: { client: 'pg', connection: { host: '127.0.0.1', user: 'dbUser', password: 'dbpword', port: 5432, database: 'example-name' }, migrations: { directory: __dirname + '/db/migrations' }, seeds: { directory: __dirname + '/db/seeds/development' } }, } //db.js const config = require('../knexfile.js');

I'm still not sure how to do my migrations with knex. Here is what I have so far. It works on up , but down gives me FK constraint error even though foreign_key_checks = 0. exports.up = function(knex, Promise) { return Promise.all([ knex.raw('SET foreign_key_checks = 0;'), /* CREATE Member table */ knex.schema.createTable('Member', function (table) { table.bigIncrements('id').primary().unsigned(); table.string('email',50); table.string('password'); /* CREATE FKS */ table.bigInteger('ReferralId').unsigned().index(); table.bigInteger('AddressId').unsigned().index().inTable('Address').references(

I'm trying to make transactions work with async/await and knexjs but to no avail. The code (snippet is for the sake of shortening the post): const updateOrder = (req, res, db, logger) => { let { status, trx_id, orNumber, returnReason } = req.body; const updateStatus = () => { return db('cart') .returning('*') .where('trx_id', '=', trx_id) .update({ status: status, or_num: orNumber, return_reason: returnReason }); } const updateDate = () => { return db('cart') .returning('*') .where('trx_id', '=', trx_id) .update({ date_purchased: new Date() }); } const selectItems = (order) => { return db

I'm currently using NodeJS with knex (Postgresql) for database stuff. Problem: Imagine the following two tables in database: Table 1 PROJECT id (pk) name Table 2 EMPLOYEE id (pk) name project_id (fk) I want to create a json-response to the user that looks like the following: { projects: [ { id: 1, name: 'emxample 1', employees: [ { id: 1, name: 'example 1' }, { id: 2, name: 'example 2' } ] } ] } and so on. Making a query like: let query = knex('project').select('project.*', 'employee.*').join('employee', 'employee.project_id', '=', 'project.id'); query.then((projects) => { res.json(projects);

How do we get Knex to create the following SQL statement: UPDATE item SET qtyonhand = qtyonhand + 1 WHERE rowid = 8 We're currently using the following code: knex('item') .transacting(trx) .update({qtyonhand: 10}) .where('rowid', 8) However, in order for our inventory application to work in a multi-user environment we need the qtyonhand value to add or subtract with what's actually in the database at that moment rather than passing a value that may be stale by the time the update statement is executed. Here are 2 different ways knex('item').increment('qtyonhand').where('rowid',8) or knex('item

I would like to monitor the time taken by a query on my API's db. I so created the following function, using bookshelf-signals, a Bookshelf plugin. : bookshelf.on('fetching', () => { server.app.fetching = new Date().valueOf(); }); bookshelf.on('counting', () => { server.app.fetching = new Date().valueOf(); }); bookshelf.on('fetched', () => { server.statsd.gauge('db_query', new Date().valueOf() - server.app.fetching); }); ... so that I can retrieve the time just before and just after a fetch/count; I did the same with deleting-deleted and saving-saved. What I think I fail to understand is when
