For example I have two models with 1:N
const Product = db.define("product", {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true
},
name: {
type: Sequelize.STRING
}
});
const Category = db.define("category", {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true
},
name: {
type: Sequelize.STRING
}
});
Product.Category = Product.belongsTo(Category);
Category.Product = Category.hasMany(Product);
If I want create category and products together I do:
await Category.create(
{
name: "test-category-2",
products: [{ name: "p1" }, { name: "p2" }]
},
{ include: [Product] }
);
How can I create instance with existing associations, for example I have products and want to add/update category(categoryId) relation with new category, something like this:
const category = await Category.create(
{
name: "test-category-1",
products: [products[0].id, products[1].id] // add/update categoryId in this products
},
);
It must create new category and update existing products categoryId, but in code above it try to create products like in first example
