I have a nodejs app using sequelize and postgres as a database, the architecture of the app is multitenant with separate schemas in the same database, the problem I present is that when including the permissions model in the user query, sequelize It doesn't take me the schema for the join table and therefore tries to query it in the default schema (public). these are my models:
Users:
export const USERS_TABLE = 'users';
#Table({

export class User extends Model {

Join Table
export const USERS_PERMISSIONS_TABLE = 'user_permissions';
#Table({

export class UserPermission extends Model {

#Column({

allowNull: false,

onDelete: 'SET NULL',
})
permissionId: string;
}
I pass the necessary parameters to a base class that performs my query
users = await super.getAll(
tenantId,
[
Role.schema(schemaName),
Profile.schema(schemaName),
Subscription,
Permission.schema(schemaName),
],
body.page,
body.size,
{},
);
findAll method of Super Class
public async getAll(
tenantId: string,
includeModel?: object,
page?: string,
size?: string,
where?: Record<string, unknown>,
) {
try {
// free_id
let records: unknown;
const free = tenantId.split('_');
const tenantName: string = getTenantName(tenantId);
if (free[0] === 'free') {
where.tenantId = free[1];
}
if (!includeModel) {
const { limit, offset } = paginate(page, size);
records = await this.model.schema(tenantName).findAndCountAll({
where,
limit,
offset,
});
return new HttpResponse.getSuccessful(records);
}
const { limit, offset } = paginate(page, size);
records = await this.model.schema(tenantName).findAndCountAll({
where,
limit,
offset,
include: includeModel,
});
return new HttpResponse.getSuccessful(records);
} catch (e) {
throw boom.badRequest(e);
}
}
The generated query And The error:
sql: `SELECT count("User"."user_id") AS "count" FROM "free_trial"."users" AS "User" LEFT OUTER JOIN "free_trial"."roles" AS "Role" ON "User"."role_id" = "Role"."role_id" LEFT OUTER JOIN "free_trial"."profiles" AS "Profile" ON "User"."profile_id" = "Profile"."profile_id" LEFT OUTER JOIN "subscriptions" AS "Subscription" ON "User"."subscription_id" = "Subscription"."subscription_id" LEFT OUTER JOIN ( "user_permissions" AS "Permissions->UserPermission" INNER JOIN "free_trial"."permissions" AS "Permissions" ON "Permissions"."permission_id" = "Permissions->UserPermission"."permission_id") ON "User"."user_id" = "Permissions->UserPermission"."user_id" WHERE "User"."tenant_id" = '72a5afbe-dc66-4b54-a428-d7bed9a2cbd9';`,

},

}
}
As can be seen in the query, all the tables are preceded by the name of the schema in which they are found, but in the join table it refers to the public schema and therefore it cannot be found; I have already tried thousands of ways but nothing seems to work, any ideas are appreciated.
I have tried to pass the name of the schema to the join table, referring to it in the include but it does not give results, I also tried within permissions to include the join table to be able to pass the name of the schema.

I need that when registering the user, the account should also be created automatically and I managed to do this using sequelize hooks, but the accountId I am not able to insert its value automatically and it always has a null value, I need that when the accountId has the id of Account, but I don't know how to do that
My models
import { Model, DECIMAL, INTEGER } from 'sequelize';
import db from '.';
class Account extends Model {
id!: number;
balance!: number;
};
Account.init({
id: {
type: INTEGER,
allowNull: false,
primaryKey: true,
autoIncrement: true
},
balance: {
type: DECIMAL(13, 2),
allowNull: false
},

export default Account;

User.belongsTo(Account, {foreignKey: 'accountId', as: 'idAccount'});
export default User;

I've tried going through the hooks and inserting auto increment as well

I have 1:n association User -> Cart, what I want is, I find User by Id then create Cart by that instance and then fill the product_id manually
I'm using sequelize
I have tried get,set,create from this association and none of them worked, it gave me this error

After executing the db migration, I define models below:
models/category.ts:
import { Model, DataTypes, BelongsToManyGetAssociationsMixin } from 'sequelize';
import { sequelize } from '../db';
import { Film } from './film_category';
class Category extends Model {
public ID!: number;
public Name!: string;
public Last_Update!: Date;
public getFilms!: BelongsToManyGetAssociationsMixin<Film>;
}
Category.init(
{
ID: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false,
},
Name: {
type: DataTypes.STRING(20),
allowNull: false,
},
Last_Update: {
type: DataTypes.DATE,
allowNull: false,
},
},
{ sequelize, modelName: 'Category' },
);
export { Category };
models/film.ts:
import { Model, DataTypes, BelongsToManyGetAssociationsMixin } from 'sequelize';
import { sequelize } from '../db';
import { Category } from './film_category';
class Film extends Model {
public ID!: number;
public LanguageID!: number;
public Title!: string;
public Description!: string;
public Release_Year!: number;
public Rental_Duration!: number;
public Rental_Date!: number;
public Length!: number;
public Replacement_Cost!: number;
public Rating!: number;
public Last_Update!: Date;
public Special_Features!: string;
public Fulltext!: string;
public getCategories!: BelongsToManyGetAssociationsMixin<Category>;
}
Film.init(
{
ID: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false,
},
LanguageID: {
type: DataTypes.INTEGER,
references: {
model: 'Language',
key: 'ID',
},
onDelete: 'restrict',
allowNull: false,
},
Title: {
type: DataTypes.STRING,
allowNull: false,
},
Description: {
type: DataTypes.STRING,
allowNull: false,
},
Release_Year: {
type: DataTypes.INTEGER,
allowNull: false,
},
Rental_Duration: {
type: DataTypes.INTEGER,
allowNull: false,
},
Rental_Date: {
type: DataTypes.DECIMAL(19, 0),
allowNull: false,
},
Length: {
type: DataTypes.INTEGER,
allowNull: false,
},
Replacement_Cost: {
type: DataTypes.DECIMAL(19, 0),
allowNull: false,
},
Rating: {
type: DataTypes.INTEGER,
allowNull: false,
},
Last_Update: {
type: DataTypes.DATE,
allowNull: false,
},
Special_Features: {
type: DataTypes.STRING,
allowNull: false,
},
Fulltext: {
type: DataTypes.STRING,
allowNull: false,
},
},
{ sequelize, modelName: 'Film' },
);
export { Film };
models/film_category.ts:
import { Model, DataTypes } from 'sequelize';
import { sequelize } from '../db';
import { Category } from './category';
import { Film } from './film';
class FilmCategory extends Model {
public FilmID!: number;
public CategoryID!: number;
public Last_Update!: Date;
}
FilmCategory.init(
{
FilmID: {
type: DataTypes.INTEGER,
primaryKey: true,
references: {
model: 'Film',
key: 'ID',
},
onDelete: 'restrict',
},
CategoryID: {
type: DataTypes.INTEGER,
primaryKey: true,
references: {
model: 'Category',
key: 'ID',
},
onDelete: 'cascade',
},
Last_Update: {
type: DataTypes.DATE,
allowNull: false,
},
},
{ sequelize, modelName: 'Film_Category' },
);
export { FilmCategory, Film, Category };
models/index.ts:
import { Category } from './category';
import { Film } from './film';
import { Language } from './language';
import { FilmCategory } from './film_category';
Category.belongsToMany(Film, { through: FilmCategory });
Film.belongsToMany(Category, { through: FilmCategory });
Language.hasMany(Film);
export { Category, Film, Language, FilmCategory };
When I try to call Film.findByPk(1), sequelize throw an error:
SequelizeDatabaseError: column "CategoryID" does not exist
The SQL query generated by sequelize of Film.findByPk(1) like this:
Executing (default): SELECT "ID", "LanguageID", "Title", "Description", "Release_Year", "Rental_Duration", "Rental_Date", "Length", "Replacement_Cost", "Rating", "Last_Update", "Special_Features", "Fulltext", "CategoryID" FROM "Film" AS "Film" WHERE "Film"."ID" = 1;
I know when I use Film.belongsToMany(Category, { through: FilmCategory });, sequelize will add CategoryID of target model Category to source model Film. I expect the film data find by primary key has the same properties as the model schema. This extra CategoryID column is the issue.
So I don't want this CategoryID column to be added on Film model and FilmID column to be added on Category model. Because Film table doesn't have CategoryID column and Category table doesn't have FilmID column in the database. They are connected by the join table Film_Category. Is there any way to do this? Or, am I missing something?
Created a minimal reproducible code repo: https://github.com/mrdulin/node-sequelize-examples/tree/master/src/db
Should work if you explicitly define the 'through' table in the association, like so:
Film.belongsToMany(Category,
{
through: FilmCategory,
foreignKey: 'FilmID',
otherKey: 'CategoryID'
});
It's possible the problems may occurs because you're using ID rather than Id, but that is just speculation...
HTH
I have the following error:
Unhandled rejection Error: Cyclic dependency found. coupons is
dependent of itself. Dependency chain: coupons -> orders => coupons
My order.js model looks like as follows:
'use strict';
module.exports = (sequelize, DataTypes) =>
{
var Order = sequelize.define('orders',
{
id:
{
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: DataTypes.INTEGER
},
userid:
{
type: DataTypes.INTEGER,
references:
{
model: 'users',
key: 'id'
}
},
coupon_id:
{
type: DataTypes.INTEGER,
allowNull: true,
references:
{
model: 'coupons',
key: 'id'
},
},
product:
{
type: DataTypes.INTEGER,
references:
{
model: 'products',
key: 'id'
}
},
address:
{
type: DataTypes.INTEGER,

{
model: 'address',
key: 'id'
}
},
canceled:
{
type: DataTypes.INTEGER,

},
quantity:
{

},
note:
{
allowNull: true,
type: DataTypes.STRING
},
},
{
freezeTableName: true,
tableName: 'orders',
createdAt: 'createdat',
updatedAt: 'updatedat',
});
Order.associate = models => {
Order.hasMany(models.coupons, {
foreignKey: 'id',
onDelete: 'cascade',
onUpdate: 'cascade',
constrains: false
});
};
return Order;
};
and coupon.js looks like this:
'use strict';
module.exports = (sequelize, DataTypes) =>
{
var Coupon = sequelize.define('coupons',
{
id:
{
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: DataTypes.INTEGER
},
name:
{
type: DataTypes.STRING
},
code:
{
type: DataTypes.STRING
},
discount:
{
type: DataTypes.FLOAT
},
expires:
{
type: 'TIMESTAMP',
},
created_by:
{
type: DataTypes.INTEGER,
references:
{
model: 'users',
key: 'id'
},
},
maxuse:
{
type: DataTypes.INTEGER,
},
},
{
freezeTableName: true,
tableName: 'coupons',
createdAt: 'createdat',
updatedAt: 'updatedat'
});
Coupon.associate = models => {
Coupon.belongsTo(models.orders,
{
foreignKey: 'id',
onDelete: 'cascade',
onUpdate: 'cascade',
});
};
return Coupon;
};
It seems that I am doing something wrong with the associations. Any help would be appreciated.
NOTE: Everytime I comment out coupon_id: on orders.js, the error goes out. Still, I need this functionality.
