Sequelize bulk insert with associations - node.js

Question

I'm trying to bulk insert with associations,
I have this 'Song' model which have one to many relationships with 'Genre' and 'Language' defined with the migrations CLI.
Song:
module.exports = (sequelize, DataTypes) => {
class Song extends Model {
static associate(models) {
// define association here
Song.hasMany(models["Language"])
Song.hasMany(models["Genre"])
}
};
Song.init({
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
primaryKey: true
},
name: DataTypes.STRING,
energy: {type: DataTypes.FLOAT, allowNull: false},
valence: {type: DataTypes.FLOAT, allowNull: false}
}, {
sequelize,
modelName: 'Song',
timestamps: true
});
return Song;
};
Language:
module.exports = (sequelize, DataTypes) => {
class Language extends Model {
static associate(models) {
// define association here
models["Language"].belongsTo(models["Song"])
}
};
Language.init({
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
primaryKey: true
},
name: DataTypes.STRING
}, {
sequelize,
modelName: 'Language',
indexes: [{unique: true, fields: ['name']}]
});
return Language;
};
Genre:
module.exports = (sequelize, DataTypes) => {
class Genre extends Model {
/**
* Helper method for defining associations.
* This method is not a part of Sequelize lifecycle.
* The `models/index` file will call this method automatically.
*/
static associate(models) {
// define association here
models["Genre"].belongsTo(models["Song"])
}
};
Genre.init({
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
primaryKey: true
},
name: DataTypes.STRING
}, {
sequelize,
modelName: 'Genre',
indexes: [{unique: true, fields: ['name']}]
});
return Genre;
};
I'm trying to bulk insert songs with languages and genres like this:
Song.bulkCreate(songs, {
include: [Genre,Language]
}).then(() => {
const result = {
status: "ok",
message: "Upload Successfully!",
}
res.json(result);
});
each song in the songs array is structured like this:
{
name: "abc",
genres: [{name: "abc"}],
languages: [{name: "English"}],
energy: 1,
valence: 1
}
I'm ending up with a full songs table but genres and languages are empty
What am I doing wrong?
Thanks.

Answer 1

Just in case anyone else got here from a search, starting from version 5.14
Sequelize added the option to use include option in bulkCreate as follows:
await Song.bulkCreate(songsRecordsToCreate, {
include: [Genre,Language]
})

Edit 2nd Feb 2023
As none answered above, as of v5.14.0 the include option is now available on bulkInsert.
Unfortunately bulkCreate does not support include option like create do.
You should use create in a cycle inside a transaction.
const transaction = ...
for (const song of songs) {
await Song.create(song, {
include: [Genre,Language]
}, { transaction })
}
await transaction.commit()
or you can use Promise.all to avoid using for.
