sequelize.js

问题 I'm trying to make login work, using the tutorial I've found in http://code.tutsplus.com/tutorials/authenticating-nodejs-applications-with-passport--cms-21619. I modified the code to work with Sequelize. I was able to verify username and password, but after serializing a user, the page that it redirects to does not load. I was wondering if there's something I missed. I'm not really getting an error, but redirecting to /test/home page is stuck on pending, and it keeps executing a post request.

问题 I'm new to sequelize, i'm trying to load all entries in my user table where the task relation is null. but its not working. here is what i have tried: const express = require('express'); const app = express(); const Sequelize = require('sequelize'); const sequelize = new Sequelize('sequelize', 'mazinoukah', 'solomon1', { host: 'localhost', dialect: 'postgres', pool: { max: 5, min: 0, acquire: 30000, idle: 10000, }, }); const Task = sequelize.define('Task', { name: Sequelize.STRING, completed:

问题 I'm running an into issue where Sequelize creates a subquery of the primary model and then joins the includes with that subquery instead of directly with the primary model table. The query conditions for the include(s) ends up inside the subquery's WHERE clause which makes it invalid. I have shortened names down trying to keep this compact hopefully without losing any relevant info. Environment: Nodejs: 6.11.3 Sequelize: 3.23.6 => Updated to 4.38.1 and problem persists MySql: 5.7.23 Code snip

问题 I tried to select from a table with reference another table. I have a relationship many-to-many between table food and table Ingredients. Food model: module.exports = function(sequelize, DataTypes) { return sequelize.define('food', { id: { type: DataTypes.INTEGER(10), allowNull: false, primaryKey: true, autoIncrement: true }, name_food: { type: DataTypes.STRING, allowNull: false } }, { tableName: 'food', freezeTableName: true }); }; Food_ingredients model: module.exports = function(sequelize,

问题 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. 回答1: In the configuration section of Sequelize.js there is no direct option that can be activated to truncate the characters

问题 I'm having trouble getting Sequelize.js to soft delete the rows in my table. I used Sequelize cli to do all my migrations and I'm not using the sync feature to resync the database on start. I have the timestamp fields and even the deletedAt field in my migration and models (model has paranoid: true also) and no matter what it still deletes the row instead of adding a timestamp to the deletedAt field. I noticed when do any querying it doesn't add the deletedAt = NULL in the query like I've

问题 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 need to have video.get/setFirstFrame() and video.get/setLastFrame() functions available. How can I

问题 I have two models Contact and Thread with a many to many relationship represented across a join table ThreadContacts . I need to write a query to find a Thread which has associations with an exact list of Contacts .
