knex.js

问题 I am trying to get knex working in my node.js application. I was following a tutorial and at some point created a table but could not repeat the process. I removed the table and deleted all the migrations folders. At tis point I started over but after creating a new migration and then running knex migrate:latest I get an error saying the migration directory is corrupt because the original migration I had is missing. I was under the impression that if the file is missing it should not know it

问题 While testing a Bookshelf model insert using the oracledb client (versions bellow), I'm having an strange error. I've tested same code with mysql , pg and sqlite3 clients with no problem in this operation. My model is this: Promotion = bookshelf.model('Promotion', { tableName: 'promotions' }) And the action that triggered the error is this: Promotion.forge({image:"image","featured":false,"price":"2.33","name":"name","description":"description"}).save(null, { method:'insert' }) The insertion

问题 I have a table with column table.decimal('some_column', 30,15) which on postgres is numeric(30,15) When I run a knex.raw('select some_column from some_table') from node, the response I get in rows is like: some_column: "5.000000000000000" some_column: "10.000000000000000" What really pointed me to this is that I do something like firstValue>lastValue I end up with a true response so that makes me think that these are returned as strings and not as numbers. Any way to override this behavior?

问题 I'm using knex with pg. I have a project similar as following. dbClient.js const dbClient = require('knex')({ client: 'pg', connection: { host: '127.0.0.1', user: 'user', password: 'password', database: 'staging', port: '5431' } }) module.exports = dbClient libs.js const knex = require('./dbClient.js') async function doThis(email) { const last = await knex('users').where({email}).first('last_name').then(res => res.last_name) // knex.destroy() return last } async function doThat(email) { const

问题 Code Preferred way this.related('title').save({value: input}); But as this line is cut and pasted from a middle of some abstract class, below is a more decoupled way of directly reproducing the same error message. Alternative Implementation let title = await book.related('title'); title.set({value: inputs.title}); title.save().then( (model) => {} ); Error message Unhandled rejection Error: Undefined binding(s) detected when compiling SELECT. Undefined column(s): [titles.titleable_id] query:

问题 I have a node.js backend that constructs DB queries dynamically from various inputs using Knex.js. Some of the inputs need to be processed asynchronously. My problem is, that I can't return a knex query object from an async function (or of course in a Promise resolve function) because this triggers the execution of the query. Currently I need to process all my async inputs before handing them to the query building functions but that really limits their composability. Is there a way to prevent
