sequelize.js

问题 I'm trying to migrate a db with Sequelize working with MySQL 8.0.15, but I'm not able to do that. I keep receiving this error message. Sequelize CLI [Node: 10.15.0, CLI: 5.4.0, ORM: 5.3.5] Loaded configuration file "config/config.json". Using environment "development". ERROR: Client does not support authentication protocol requested by server; consider upgrading MySQL client I've tried every single solution for this problem. The thing is when i try to change the MySQL root password the

问题 I change MySQL databese into postgreSQL in sequelize. But After migration I have issue with upper and lowercase first letter in Table or Model... Before my MySQL version was working properly but after migration I got error message: 500 SequelizeDatabaseError: relation "Users" does not exist My User model: module.exports = function(sequelize, Sequelize) { var User = sequelize.define("User", { // profile userlevel: Sequelize.STRING, restaurant: Sequelize.STRING, access: Sequelize.STRING,

问题 I like to convert the following query into sequelize code select * from table_a inner join table_b on table_a.column_1 = table_b.column_1 and table_a.column_2 = table_b.column_2 I have tried many approaches and followed many provided solution but I am unable to achieve the desired query from sequelize code. The max I achieve is following : select * from table_a inner join table_b on table_a.column_1 = table_b.column_1 I want the second condition also. and table_a.column_2 = table_b.column_2

问题 I've got feathers.js functioning with mysql via sequelize. This is working, I can collect data from tables. Next step is to define 'joins' in the models. I have a table with a column 'status_id' and 'country_id'. These columns reference to an id in a metadata table. In SQL I would right: SELECT status.description, country.description, detail FROM details INNER JOIN metadata status ON (details.status_id = status.id AND status.type = 'status' INNER JOIN metadata country ON (details.country_id

问题 Okay so i have the following three models Module: var Module = sequelize.define('module', { id: DataTypes.INTEGER, name: DataTypes.STRING, description: DataTypes.STRING, category_id: DataTypes.STRING, module_type_id: DataTypes.STRING, gives_score: DataTypes.INTEGER, duration: DataTypes.STRING, price: DataTypes.STRING }, { freezeTableName: true} ) Competence: Competence = sequelize.define('competence', { id: DataTypes.INTEGER, name: DataTypes.STRING, organization_id: DataTypes.INTEGER,

问题 I am using the sequelize ORM in my nodejs app and it seems that it drops table in the wrong order when I sequelize.sync({force: true}) For example, with: var StationEntity = sequelize.define('Station', { id: { type: Sequelize.INTEGER, primaryKey: true, allowNull: false}, name: { type: Sequelize.STRING, allowNull: false} }) var StationSnapshotEntity = sequelize.define('StationSnapshot', { id: { type: Sequelize.BIGINT, autoIncrement: true, primaryKey: true}, snapshotTimestamp: { type: Sequelize

问题 I am using sequelize ORM in node js. I am join two table and get result but that result return with table name as prefix. var Sequelize = require('sequelize'); var sequelize = new Sequelize('test', 'root', '', { // configuration } }); const db = {}; db.Sequelize = Sequelize; db.sequelize = sequelize; db.role = require('./../model/definitions/role')(sequelize, Sequelize); db.admin = require('./../model/definitions/admin')(sequelize, Sequelize); db.admin.findAll({ include: [{ model: db.role,

问题 I have a problem with Sequelize when limiting results and including associated models. The following produces the correct result, limited by 10 and sorted correctly. Visit.findAll({ limit: 10, order: 'updatedAt DESC', }).success(function(visits) { res.jsonp(visits); }).failure(function(err) { res.jsonp(err); }) SQL SELECT * FROM `Visits` ORDER BY updatedAt DESC LIMIT 10; However when I add an association it suddently limits on the subquery instead and thus the ordering never happens because

问题 Right now I have only this code: const Sequelize = require('sequelize'); const sequelize = new Sequelize('database', 'root', 'passwd', { host: 'localhost', dialect: 'mysql', // http://docs.sequelizejs.com/manual/tutorial/querying.html#operators operatorsAliases: false }); sequelize .authenticate() .then(() => { console.log('Connection has been established successfully.'); }) .catch(err => { console.error('Unable to connect to the database:', err); }); But when I try to run the .js I get this

问题 I have added a model and a migration file using this command node_modules/.bin/sequelize model:generate --name User --attributes firstName:string,lastName:string,email:string Now I wanted to add few more fields like gender and age in to the existing table(model). I changed model manually and fire this command node_modules/.bin/sequelize db:migrate But it is responding that "No migrations were executed, database schema was already up to date. " User.js 'use strict'; module.exports = (sequelize
