Home Querying 3 entities with Sequelize
 I have 3 entities, I want to find a group of elements based on one parameter. Example: A (id,...) B (id, id_A) C (id, ..., id_A, id_B)  I have already done all the relationships. My goal is to insert in a query in javascript that takes in input A_id and the results are all B that containing C. I try with something like that but I'm stuck: return C.findAll({attributes: ['id','username'] , where : { id_A : A.id } }).then(C => { //I DON'T KNOW HOW TO CONTINUE })
