How to insert foreign key in sequelize model

问题

I have a User model and a Houses model in sequelize. I also have a UserHouse model that contains {user_id, house_id}. How do I populate values in the UserHouse model.

I went through the sequelize documentation but could not get a clear idea. I need to know, how to insert user_id and house_id in UserHouse model.

I also cannot understand what associations should I use between these models.

Any help will be appreciated.

Edited:

One More issue: I have one more model HouseInfo that stores house_id (foreign key), how should I store this "house_id" foreign key in db and how should I associate the models.

回答1:

User.belongsToMany(House, { through: UserHouse });
House.belongsToMany(User, { through: UserHouse });

user.addHouse(house);
house.setUsers([user1, user2])
