sequelize.js

I am having a problem with my many to many configuration with Sequelize, where it complains that site_article_keyword is not associated to article_keyword . The code below represents a minimal test case to try to understand what I am doing wrong (I hoped to provide something smaller, but this is what I have). I am using bluebird for the Promise API. const Sequelize = require('sequelize'); var sequelize = new Sequelize(undefined, undefined, undefined, { dialect: 'sqlite', storage: './mydatabase', }); const SiteArticle = sequelize.define('site_article', { id: { type: Sequelize.INTEGER,

I need to create a custom join condition using Sequelize.js with MSSQL. Specifically, I need to join TableB based on a COALESCE value from columns in TableA and TableB and end up with a join condition like this: LEFT OUTER JOIN [TableB] ON [TableB].[ColumnB] = COALESCE ( [TableC].[ColumnC], [TableA].[ColumnA] ) I'd settle for an OR clause in my join: LEFT OUTER JOIN [TableB] ON [TableB].[ColumnB] = [TableA].[ColumnA] OR [TableB].[ColumnB] = [TableC].[ColumnC] I read that you can achieve behaviour like this by including required: false in your scope definition. As you can see, I've plastered my

I have a Sequelize findOne function that looks to select a row where the given point intersects a polygon (col 'geom') AND status = 'active'. var point = sequelize.fn('ST_GeomFromText', 'POINT(' + lng + ' ' + lat +')', 4326); var intersects = sequelize.fn('ST_Intersects', sequelize.col('geom'), point); GeoCounty.findOne({ attributes: ['id', 'name' ], where: { status: 'active', $and: intersects }, plain: true }) As of right now, it works just fine. It produces SQL that looks like: SELECT "id", "name" FROM "geocounty" AS "geocounty" WHERE "geocounty"."status" = 'active' AND (ST_Intersects("geom"

Hi I am trying to associate my User model with login model and Question_details models.But if i am using the Question_details association then i am geeting eagerLodingError :user is not associated to login but if i am commenting it then it works fine so how can i associate it ?

Hi I'm developing a chat app and just want to know how do I fetch data from other fields of a table on mysqldatabase using sequelize because I'm totally new on this. Here is how I tried to do it: io.on('connection', function(socket){ // Send all previously sent messages for( i in messages ) { socket.emit('chat message', messages[i]); } socket.on('chat message', function(msg){ console.log('message: ' + msg); // Push the message into the in-memory array. messages.push(msg); // Storage the message for when the application is restarted. sequelize.query('INSERT INTO chat_storage(chat) VALUES("'+msg

I have two models, Video and Frame. Frame.belongsTo(models.Video); Video.hasMany(models.Frame, { as: "Frames" }); I now need a way to specify first and last frame for a video, but can't get it to work. I tried this: Video.hasOne(Frame, { as: "FirstFrame" }); Video.hasOne(Frame, { as: "LastFrame" }); but that creates FirstFrameId and LastFrameId in the Frames table instead of the Videos table. I need to have video.get/setFirstFrame() and video.get/setLastFrame() functions available. How can I do this? Ellebkey You don't need to set belongTo and hasMany as you show at first. Use only one

In my model I have defined a column of size 15. column: { type: Sequelize.STRING(15), allowNull: false } The input string is 28 characters, I would like to know how to sequelize.js automatically truncate the string so that only 15 characters remain. Currently I get the following error: Unhandled rejection SequelizeDatabaseError: String or binary data would be truncated. In the configuration section of Sequelize.js there is no direct option that can be activated to truncate the characters. But to the model you can add validations including custom functions. The documentation says the following:
