Rails 7: How to Handle Circular Dependencies in ActiveRecord Associations?
I'm stuck on something that should probably be simple. I've been banging my head against this for hours... I'm working on a Rails 7 application where I have two models, `User` and `Profile`, that reference each other through `belongs_to` and `has_one` associations. The `User` model has many profiles, while each profile belongs to a user. The scenario arises when I try to load the user with their profiles, leading to a circular dependency behavior. I'm working with the following behavior message: `ActiveRecord::AssociationTypeMismatch: User(#123) expected, got Profile(#456)`. Here's a simplified version of my models: ```ruby class User < ApplicationRecord has_many :profiles end class Profile < ApplicationRecord belongs_to :user end ``` When I attempt to fetch a user with their profiles like this: ```ruby user = User.includes(:profiles).find(1) ``` I expect to get the user and all associated profiles without issues. However, I get the circular dependency behavior instead. I have also tried using `eager_load` and `joins` but faced similar problems. Additionally, I ensured that all relevant migrations were run, and the associations seem correctly set up with foreign keys. My database is PostgreSQL, and I'm using Rails 7.0.4. I would appreciate any guidance on how to resolve this circular reference scenario or suggestions on best practices for handling such associations in Rails. Thank you!
