Hi, I am quite a newbie on Elixir, I come from rails. And keep trying how to figure out what is the best way for handling a one-to-many through a join table. A user have many rooms. But not all users only user with the admin role. So there is User table, Room table Admin the join table . schema…

Hello and welcome, It is not common to do one_to_many with a join table… usually it is done through a simple key on the belongs side. I cannot recall where, but I think it is advised to do a many_to_many, even if it is a one to many relationship.

[image] edcock: What is the more idiomatic way to udpate the Admin for a given Room ? More idiomatic than what? How are you updating it now? Why do you need a join table here? Why not just a admin_id on the room itself?
