I am unable to update row using sequelize. It seems like it's skipping the query because no logs are generated in the terminal when updating. Other operations like insert and destroy are working fine.
UPDATE CODE
const uuid = require('uuid/v4');
const db = require('../../models');
const TempToken = db.tempTokens;
exports.generateToken = async (req) =>{
'use strict';
const token = uuid();
// let transaction = await db.sequelize.transaction();
try{
console.log(req.userId); /////////// DATA prints in console
console.log(req.device.type); /////////// DATA prints in console
const insert = {
user: req.userId,
device: req.device.type,
};
await TempToken.update({valid: false}, {where:{id: 9 } });
insert['token'] = token;
insert['deviceConfig'] = JSON.stringify(req.device);
await TempToken.create(insert);
return token;
}
catch (e){
return e;
}
};
TempTokens model -
/* jshint indent: 2 */
module.exports = function(sequelize, DataTypes) {
return sequelize.define('tempTokens', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true,
},
user: {
type: DataTypes.STRING(225),
allowNull: true,
},
token: {
type: DataTypes.STRING(225),
allowNull: false,
},
device: {
type: DataTypes.STRING(225),
allowNull: true,
},
deviceConfig: {
type: DataTypes.TEXT,
allowNull: true,
},
valid: {
type: DataTypes.BOOLEAN,
allowNull: false,
default: true,
},
}, {
tableName: 'tempTokens',
});
};
Data in req.userId and req.device.type are valid. And, id:9 is also valid and present in table.
Terminal log is -
Executing (default): INSERT INTO `tempTokens` (`id`,`user`,`token`,`device`,`deviceConfig`,`createdAt`,`updatedAt`) VALUES (DEFAULT,?,?,?,?,?,?);
Any help will be appreciated
I think it should be defaultValue not default:
valid: {
type: DataTypes.BOOLEAN,
allowNull: false,
defaultValue: true,
}

Bug Description
after running sequelize sync with options alter: true, all foreign keys in tables set to null.
await sequelize.sync({ alter: true }).then(async (result) => {
await initDataUserGroup();
await initDataUserAdmin();
await initDataGateType();
});
and here my one model which has foreign key :
const { DataTypes } = require("sequelize");
const { sequelize } = require("../services/DatabaseService");
const UserGroup = require("./UserGroup");
const Biodata = require("./Biodata");
const User = sequelize.define("user", {
username: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
validate: {
notNull: {
msg: "Username must not be empty",
},
notEmpty: true,
},
},
email: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
validate: {
notNull: true,
notEmpty: true,
isEmail: true,
},
},
password: {
type: DataTypes.STRING,
allowNull: false,
validate: {
notNull: true,
notEmpty: true,
},
},
});
User.UserGroup = User.belongsTo(UserGroup);
User.Biodata = User.hasOne(Biodata, {
foreignKey: "userId",
as: "biodata",
});
module.exports = User;
What do you expect to happen?
It should not set all foreign keys to null after running sync with options { alter: true }
What is actually happening?
userGroupId in table user is null and userId in table biodata is also null.
Environment
Sequelize version: ^6.6.5
Node.js version: 12.9.1
Dialect: SQLite (SQLite3)
From my issue : https://github.com/sequelize/sequelize/issues/13464
anyone can help me please?
after struggling for a couple of days, I managed to resolve it by disabling and re-enabling foreign keys before and after syncing :
await sequelize.query("PRAGMA foreign_keys = false;");
await sequelize
.sync({ alter: true })
.then(async (result) => {
await initDataUserGroup();
await initDataGateType();
})
.catch((errorMessage) => console.error("sync error = ", errorMessage));
await sequelize.query("PRAGMA foreign_keys = true;");
Feel free to inform me a better solution than the current one.
i'm using NodeJS & Sequelize for a school project and i'm struggling on making associations w/ sequelize work. I tried a couple of things before but nothing that made my day.
Basically the thing is that a user can have several playlists (hasMany).
And a playlist belongs to a user (belongsTo).
My error is:
Association with alias "playlist" does not exist on users
Here are my models:
/* USER MODEL */
const Sequelize = require('sequelize');
const { db } = require('../utils/db');
const User = db.define('users', {
id: {
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: Sequelize.INTEGER,
},
userID: {
type: Sequelize.INTEGER,
allowNull: false,
field: 'user_id',
},
firstName: {
type: Sequelize.STRING,
field: 'first_name',
allowNull: false,
},
}, {
underscored: true,
tableName: 'users',
freezeTableName: true, // Model tableName will be the same as the model name
});
module.exports = {
User,
};
/* PLAYLIST MODEL */
const sequelize = require('sequelize');
const { db } = require('../utils/db');
const Playlist = db.define('playlist', {
id: {
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: sequelize.INTEGER,
},
name: {
type: sequelize.STRING,
field: 'name',
allowNull: false,
},
coverUrl: {
type: sequelize.STRING,
field: 'cover_url',
allowNull: true,
},
ownerId: {
type: sequelize.INTEGER,
allowNull: false,
references: {
model: 'users',
key: 'user_id',
},
},
}, {
underscored: true,
tableName: 'playlist',
freezeTableName: true,
});
module.exports = {
Playlist,
};
Here is how i load my models:
const { Credentials } = require('./credentials');
const { User } = require('./users');
const { Playlist } = require('./playlist');
function loadModels() {
User.associate = (models) => {
User.hasMany(models.Playlist, { as: 'playlist' });
};
Playlist.associate = (models) => {
Playlist.belongsTo(models.User, { foreignKey: 'owner_id', as: 'owner' });
};
Credentials.sync({ force: false });
User.sync({ force: false });
Playlist.sync({ force: false });
}
module.exports = {
loadModels,
};
And finally here is my query where i get this error:
const express = require('express');
const { auth } = require('../../middlewares/auth');
const { Playlist } = require('../../models/playlist');
const { User } = require('../../models/users');
const router = express.Router();
router.get('/playlist', [], auth, (req, res) => {
User.findOne({
where: { userID: req.user.user_id }, include: 'playlist',
}).then((r) => {
console.log(r);
});
});
module.exports = router;
I'm trying to get all the playlist that belongs to a user.
I removed all the useless code (jwt check etc..)
So when i'm doing a get request on /playlist I get:
Unhandled rejection Error: Association with alias "playlist" does not exist on users.
I understand the error but don't understand why i get this.
What did I miss, any ideas ?
Thanks,
I finally fixed it by re-make all my models and definitions with migrations.
I had the same problem and the solution was that Sequelize pluralize the models name so in my case "playlist" does not exist on users because Sequelize pluralized my model so I had to put "Playlists" instead.
I have 2 models users and tags, both are associated through another model called usersTags and all 3 models have paranoid set with custom timestamps. I understand that associating models will add additional methods to work on the associations to all associated models, so i am wanting to making a simple setTags call for users, the docs shows that if in the array in the method does not contain the element that is stored in the database it should be removed, otherwise it should be created/restored.
So i try to restore a previously removed tag but for some reason it fails. The models are defined as following:
Users
module.exports = function(sequelize, DataTypes) {
const Users = sequelize.define("users", {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
username: {
type: DataTypes.STRING(100),
allowNull: false,
validate: {
len: {
args: [3, 100],
msg: "String length is not in this range"
}
}
},
password: {
type: DataTypes.STRING(100),
allowNull: false,
field: "password_hash"
}
}, {
tableName: "users",
createdAt: "create_time",
updatedAt: "update_time",
deletedAt: "delete_time",
paranoid: true
});
Users.associate = function(models) {
// Add this association to include tag records
this.belongsToMany(models.tags, {
through: {
model: models.usersTags,
unique: true
},
foreignKey: "users_id",
constraints: false
});
};
return Users;
};
Tags
module.exports = function(sequelize, DataTypes) {
const Tags = sequelize.define("tags", {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
name: {
type: DataTypes.STRING(45),
allowNull: false
}
}, {
tableName: "tags",
createdAt: "create_time",
updatedAt: "update_time",
deletedAt: "delete_time",
paranoid: true
});
Tags.associate = function(models) {
this.belongsToMany(models.users, {
through: {
model: models.usersTags,
unique: true
},
foreignKey: "tags_id",
constraints: false
});
};
return Tags;
};
usersTags
module.exports = function(sequelize, DataTypes) {
const UsersTags = sequelize.define("usersTags", {
users_id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
references: {
model: "users",
key: "id"
}
},
tags_id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
references: {
model: "tags",
key: "id"
}
}
}, {
tableName: "users_tags",
createdAt: "create_time",
updatedAt: "update_time",
deletedAt: "delete_time",
paranoid: true,
indexes: [
{
unique: true,
fields: ["users_id", "tags_id"]
}
]
});
return UsersTags;
};
Test
let _user;
models.users.findOne({where: {id: 100}})
.then(user => {
_user = user;
return _user.setTags([1]); // Successfully create association tag with id 1
})
.then(() => _user.setTags([])) // Successfully remove all associated tags
.then(() => _user.setTags([1])); // Should restore association tag with id 1 but fails
Executed query
app:database Executing (default): SELECT `id`, `username`, `first_name`, `last_name`, `birthday`, `description`, `location`, `email`, `type`, `image_path` FROM `users` AS `users` WHERE ((`users`.`delete_time` > '2018-08-28 19:40:15' OR `users`.`delete_time` IS NULL) AND `users`.`id` = 100); +0ms
app:database Executing (default): SELECT `users_id`, `tags_id`, `create_time`, `update_time`, `delete_time` FROM `users_tags` AS `usersTags` WHERE ((`usersTags`.`delete_time` > '2018-08-28 19:40:15' OR `usersTags`.`delete_time` IS NULL) AND `usersTags`.`users_id` = 100); +6ms

For some reason the tag search query is failing to retrieve the tag that contains the delete_time set and therefore the last query is insert instead of update, i know the workaround would be to set paranoid to false but i have to keep track of all activities, i know another workaround would be to create a custom model method to handle this but i still want to know if there is a way to achieve this without having to create an additional custom method
your code in not in a correct async order so your _user global variable is not initiated,I think this is the correct order :
let _user;
models.users.findOne({where: {id: 100}})
.then(user => {
_user = user;
_user.setTags([]).then(()=>{
_user.setTags([1])
})
})
In my project I am using MySQL database and Sequelize Js,
I have two models created:
Post code model:
module.exports = function(sequelize, Sequelize) {
var Post_code = sequelize.define('post_code', {
id: {
autoIncrement: true,
primaryKey: true,
type: Sequelize.INTEGER(11)
},
code: {
type: Sequelize.STRING(16),
allowNull: false,
unique: true
},
city: {
type: Sequelize.STRING(45),
allowNull: false
}
},{
freezeTableName: true,
underscored: true
});
Post_code.associate = function(models) {
models.post_code.hasMany(models.building);
};
return Post_code;
}
Building model:
module.exports = function(sequelize, Sequelize) {
var Building = sequelize.define('building', {
id: {
autoIncrement: true,
primaryKey: true,
allowNull: false,
type: Sequelize.INTEGER(11)
},
name: {
type: Sequelize.STRING(100),
allowNull: false
},
number: {
type: Sequelize.INTEGER(11),
allowNull: false
},
address: {
type: Sequelize.STRING(255),
allowNull: false
},
latitude: {
type: Sequelize.DECIMAL(9,6),
allowNull: false
},
longitude: {
type: Sequelize.DECIMAL(9,6),
allowNull: false
}
},{
freezeTableName: true,
underscored: true
});
Building.associate = function (models) {
models.building.belongsTo(models.post_code, {
foreignKey: {
allowNull: false
}
});
models.building.hasMany(models.flat);
};
return Building;
};
They are in relation one to many, it follows that Post code has many Buildings:
I want to add new building to database, when POST request is send to this route:
"/post-codes/:post_code_id/buildings"
I have access to post_code_id but I don't know how to correctly associate post_code model with building.
I was trying to do something like this:
models.post_code.findById(req.params.post_code_id)
.then(function(postCode){
postCode.setBuilding(
models.building.create({
}).then(function(building){});
);
});
But without result. I would be grateful if someone could explain how to make inserts correctly.
I haven't heard about the include option on create, but you can do something like this:
db.post_code.find({
where: {
id: req.params.post_code_id
}
}).then(post_code => {
if (!post_code) {
return res.status(404).send({
message: 'No post_code with that identifier has been found'
});
} else {
//create here your building
}
}).catch(err => {
return res.jsonp(err)
});
I don't know if this is the best way to do it, but it verify first if the post_code exists.
I'm using Sequelize connected to PostgreSQL and as I want to use sync function I would like to prepare valid models to create tables on every environment.
EDIT:
Wallet:
'use strict';
module.exports = function(db, DataTypes) {
var Wallet = db.define('Wallet', {
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true
},
money: {
type: DataTypes.INTEGER,
allowNull: false,
defaultValue: 0
}
createdAt: DataTypes.DATE,
updatedAt: DataTypes.DATE
}, {
tableName: 'wallet',
classMethods:{
associate : function( models ) {
Wallet.belongsTo( models.User,{ foreignKey : 'id_user'});
}
}
});
return Wallet;
};
User:
'use strict';
var bcrypt = require('bcrypt-nodejs');
var crypto = require('crypto');
var moment = require('moment');
var models = require('./');
var afterCreateHook = function(user, options, fn) {
models.Wallet.build({id_user: user.id}).save();
fn(null, user);
};
module.exports = function(db, DataTypes) {
var User = db.define('User', {
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true
},
password: DataTypes.STRING,
email: {

classMethods: {
associate : function( models ) {
User.hasOne( models.Wallet);
}
},
hooks: {
afterCreate: afterCreateHook
}
});
return User;
};
Why
models.Wallet.build({id_user: user.id}).save();
is not working? Account is creating and then I want to create wallet with specific user_id. I don't have even an error...
Help please!
You should check relations from sequelize docs
In your case youu need to define:
Wallet.belongsTo(User,{foreignKey: 'id_user'});
This will add id_user to Wallet model , so you dont need to specify id_user attribute in your WalletModel.
If you are using sequelize import function , you should add the relation in "associate" class method like this:
module.exports = function(db, DataTypes) {
var Wallet = db.define('Wallet', {
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true
},
pin: {
type: DataTypes.INTEGER,
allowNull: false,
defaultValue: 0
},
money: {
type: DataTypes.STRING,
allowNull: false,
defaultValue: 0
},
createdAt: DataTypes.DATE,
updatedAt: DataTypes.DATE
}, {
tableName: 'Wallet',
classMethods:{
associate : function( models ) {
Wallet.belongsTo( models.User,{ foreignKey : 'id_user'});
}
}
});
