Join in sequelize
I have the following database tables: Event, User and Favorite.
An event can be favorited by many users and a user can favorite many events.
The Favorite table schema is:
CREATE TABLE favorites
(
user_id INTEGER REFERENCES users(id) ON DELETE CASCADE,
event_id INTEGER REFERENCES events(id) ON DELETE CASCADE,
PRIMARY KEY (user_id, event_id)
);
What I need is a query that returns all events and information (preferably a boolean) regarding whether or not each event is favorited by a user (its ID is available and you can call it user_id).
So far I've tried:
Event.findAll({
include: {
model: sequelize.models.favorites,
required: false,
where: {
user_id: user_id
}
}
});
In the event model I have the association
models.events.belongsToMany(models.users, { through: 'favorites'});
And in the user model I have the association
models.users.belongsToMany(models.events, { through: 'favorites'});

Managed to come up with a solution:
Event.findAll({
include: {
model: sequelize.models.users,
as: 'favorite',
where: {
id: user_id
},
required: false
}
});
with the following associations:
models.users.belongsToMany(models.events, { through: 'favorites', as: 'favorite'});
models.events.belongsToMany(models.users, { through: 'favorites', as: 'favorite'});
