Adding data to a join table with Sequelize

Among the tables we have are Users, Categories, and Users_Categories.

Suppose we already have one user with user_id = 1 and one category with category_id = 1. Now, I am looking to establish a connection between them using the Users_Categories join table. How can this be achieved using Sequelize (v6)?

The association between the tables is set up as follows:

User.belongsToMany(Category, {through: User_Category});

Category.belongsToMany(User, {through: User_Category});

Answer №1

While I am familiar with using sequelize.query(...) for raw queries, I am curious if there are alternative methods to accomplish the same task.
