title: How to insert foreign key in sequelize model
body: <p>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. </p>
  
  <p>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.</p>
  
  <p>I also cannot understand what associations should I use between these models.</p>
  
  <p>Any help will be appreciated.</p>
  
  <p><strong>Edited</strong>:</p>
  
  <p><strong>One More issue:</strong>
   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.</p>
