It look as follows. router.get('/', function (req, res, next) { db.select('users.id', 'users.name', 'user_emails.address') .from('users') .leftJoin('user_emails', 'users.id', 'user_emails.user_id') .then(users => res.status(200).json(users)) .catch(next) // go to error handler }); However, this will return a new document for each email address. What I want is an array of documents that

问题 I figured it would work similarly to my delete request since it targets a specific user(delete request works perfect), so I passed an id as well to my get request. I logged the response of the request and I am given the error from my catch block in the file where I defined my sql queries using Knex, so i believe something is wrong with my sql query?. In the logged response I can also see the id of the user im wanting to display which is a good sign, so I think it has to be a minor error

问题 I have a node server that's trying to connect to a postgres database using knex. Both are in docker containers with the same custom network. I keep getting ECONNREFUSED errors. I've poked around in the database container and I see that my DB ( test_db ) has been created by psql but it has no permissions. After giving root permissions, I'm still getting the same issues. I've tried removing the volumes with docker-compose down -v but still no luck. I've also tried removing knex and just using

问题 Given that I have a Knex.js script like this: exports.up = function(knex, Promise) { return knex.schema.createTable('persons', function(table) { table.increments('id').primary(); table.string('name').notNullable(); }); }; which currently creates a table. How do I add subsequent insert statements to this script? What I want to do is add a line like this (or similar): knex.insert({id: 1, name: 'Test'}).into('persons') I'm not sure I understand how this promise-based approach works. Am I
