sequelize return only first row ( through the include association) - postgresql

Question

i am using sequelize include to associate the next three models
"moldsets" has many "molds" and "molds" has many "moldstatus"
// moldsets.model.js
const Sequelize = require("sequelize");
const DataTypes = Sequelize.DataTypes;
module.exports = function (app) {
const sequelizeClient = app.get("sequelizeClient");
const moldsets = sequelizeClient.define(
"moldsets",
{
name: {
type: DataTypes.STRING,
allowNull: false,
},
vendor: {
type: DataTypes.STRING,
allowNull: false,
},
status: {
type: DataTypes.STRING,
allowNull: false,
},
number_of_blanks: {
type: DataTypes.INTEGER,
allowNull: false,
},
number_of_blows: {
type: DataTypes.INTEGER,
allowNull: false,
},
date_of_reception: {
type: DataTypes.DATE,
allowNull: false,
},
date_of_scrap: {
type: DataTypes.DATE,
allowNull: true,
},
},
{
hooks: {
beforeCount(options) {
options.raw = true;
},
},
}
);
// eslint-disable-next-line no-unused-vars
moldsets.associate = function (models) {
// Define associations here
// See http://docs.sequelizejs.com/en/latest/docs/associations/
const { molds } = models;
// Define associations here
// See http://docs.sequelizejs.com/en/latest/docs/associations/
moldsets.hasMany(molds, { foreignKey: "moldsetId" });
};
return moldsets;
};
//molds.model.js
const Sequelize = require("sequelize");
const DataTypes = Sequelize.DataTypes;
module.exports = function (app) {
const sequelizeClient = app.get("sequelizeClient");
const molds = sequelizeClient.define(
"molds",
{
number: {
type: DataTypes.INTEGER,
allowNull: false,
},
kind: {
type: DataTypes.STRING,
allowNull: false,
},
moldsetId: {
type: DataTypes.INTEGER,
allowNull: false,
},
numberOfTotalGobs: {
type: DataTypes.INTEGER,
allowNull: false,
},
statusId: {
type: DataTypes.INTEGER,
allowNull: false,
},
note: {
type: DataTypes.STRING,
allowNull: false,
},
},
{
hooks: {
beforeCount(options) {
options.raw = true;
},
},
}
);
// eslint-disable-next-line no-unused-vars
molds.associate = function (models) {
// Define associations here
// See http://docs.sequelizejs.com/en/latest/docs/associations/
console.log(models);
const { moldsets, moldstatus } = models;
molds.belongsTo(moldsets);
molds.hasMany(moldstatus, { as: "status" });
};
return molds;
};
// moldstatus.model.js
const Sequelize = require("sequelize");
const DataTypes = Sequelize.DataTypes;
module.exports = function (app) {
const sequelizeClient = app.get("sequelizeClient");
const moldstatus = sequelizeClient.define(
"moldstatus",
{
moldId: {
type: DataTypes.INTEGER,
allowNull: false,
},
status: {
type: DataTypes.STRING,
allowNull: false,
},
startdate: {
type: DataTypes.DATE,
allowNull: false,
},
enddate: {
type: DataTypes.DATE,
allowNull: true,
},
note: {
type: DataTypes.STRING,
allowNull: true,
},
lineId: {
type: DataTypes.INTEGER,
allowNull: false,
},
section: {
type: DataTypes.STRING,
allowNull: false,
},
defect: {
type: DataTypes.STRING,
allowNull: true,
},
numberOfGobs: {
type: DataTypes.INTEGER,
allowNull: false,
},
operatorId: {
type: DataTypes.INTEGER,
allowNull: false,
},
},
{
hooks: {
beforeCount(options) {
options.raw = true;
},
},
}
);
// eslint-disable-next-line no-unused-vars
moldstatus.associate = function (models) {
// Define associations here
// See http://docs.sequelizejs.com/en/latest/docs/associations/
const { molds } = models;
moldstatus.belongsTo(molds, { foreignKey: "statusId" });
};
return moldstatus;
};
but when i query the moldset ( i am using feathersjs so i am using it in the before find hook )
const related = async (context) => {
const sequelize = context.app.get("sequelizeClient");
const { molds, moldstatus } = sequelize.models;
context.params.sequelize = {
include: [
//{ all: true, nested: true },
{
model: molds,
attributes: ["number", "statusId"],
required: false,
order: [[molds, "number", "ASC"]],
include: [
{
model: moldstatus,
as: "status",
required: false,
attributes: ["status"],
//order: [[moldstatus, "created_at", "DESC"]],
},
],
raw: false,
},
],
raw: false,
};
return context;
};
module.exports = {
before: {
all: [
authenticate("jwt"),
(context) => {
related(context);
},
],
find: [],
get: [],
create: [],
update: [],
patch: [],
remove: [],
},
};
the result is i got all the moldsets with its molds but i got only the first mold status for the first mold only in each moldset ( the other molds got empty array )
i tried setting raw to true but i still got the status for the first mold in each moldset only ...
//result

Answer 1

First of all, if you indicate a foreign key field in some association explicitly you should indicate it for the reversed association as well:
moldsets.hasMany(molds, { foreignKey: "moldsetId" });
...
molds.belongsTo(moldsets, { foreignKey: "moldsetId" });
molds.hasMany(moldstatus, { as: "status", foreignKey: "statusId" });
...
moldstatus.belongsTo(molds, { foreignKey: "statusId" });
And you indicated incorrect foreign key field for molds.hasMany(moldstatus so the above associations should be like this:
molds.hasMany(moldstatus, { as: "status", foreignKey: "moldId" });
...
moldstatus.belongsTo(molds, { foreignKey: "moldId" });
