Hello everyone, I'm a beginner Rails developer and right now am building a sample project to show off at some job apply. The app is rather simple, I guess, but I have come to some doubts on what associations to chose and why. Basically a User can create a bill(being its creditor) and the billing can have many other Users(as their debtors), so you can track up billings you share with other persons, like rent, market, food orders etc, and control what each one got to pay you. Right now I have the following model: class User < ActiveRecord::Base has_many :billings, foreign_key: "creditor_id", dependent: :destroy has_many :debts, foreign_key: "debtor_id", dependent: :destroy end class Billing < ActiveRecord::Base belongs_to :creditor, class_name: "User" has_many :debts, dependent: :destroy end class Debt < ActiveRecord::Base belongs_to :billing belongs_to :user end would this be the better approach? Or something like: User has_many billings through debts Billing has_many debts ? And in that case, would appreciate some help to model those associations, because I'm still kinda lost on this flow. Thanks in advance, Diego Dillenburg Bueno -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
