Dealing with SQL cartesians in nodeJS - node.js

Question

I've got a query that is coming back with cartesians because one of the table joins can have many results. The use case is I have a company that can have many locations.
Here's the response I'm getting in my query:
[
{
// this is the company info
oid: 31,
companyName: 'Foo Bar Inc',
avatar: 'http://placehold.it/100x100',
bannerImage: 'http://placehold.it/800x200',
// here starts the location
name: 'Foo Bar Port',
address: '1234 West 31 Street',
city: 'New York',
state: 'New York'
},
{
oid: 31,
companyName: 'Foo Bar Inc',
avatar: 'http://placehold.it/100x100',
bannerImage: 'http://placehold.it/800x200',
name: 'Foo Bar Warehouse',
address: '644 Main Street',
city: 'Los Angeles',
state: 'California'
}
]
I would eventually like to get this to turn into:
{
oid: 31,
companyName: 'Foo Bar Inc',
avatar: 'http://placehold.it/100x100',
bannerImage: 'http://placehold.it/800x200',
locations: [
{
name: 'Foo Bar Port',
address: '1234 West 31 Street',
city: 'New York',
state: 'New York'
},
{
name: 'Foo Bar Warehouse',
address: '644 Main Street',
city: 'Los Angeles',
state: 'California'
}
]
}
What is the best way to handle this?

Answer 1

This below example if you use Sequelize ORM in node.js:
Here Company and Location is model.
// Company.js
// ...
Company.associate = function(models) {
// Using additional options like CASCADE etc for demonstration
// Can also simply do Company.belongsTo(models.Location);
Company.belongsTo(models.Location, {
onDelete: "CASCADE",
foreignKey: {
allowNull: false
}
});
}
// ...
