Rails 7.1: Uncaught ActiveRecord::RecordNotFound when eager loading associations in a complex query
I keep running into I'm upgrading from an older version and I'm working with an `ActiveRecord::RecordNotFound` behavior when trying to eager load associations in a complex query in my Rails 7.1 application..... The scenario arises when I try to fetch a set of `User` records along with their associated `Posts` and `Comments`. The query looks like this: ```ruby users = User.includes(posts: :comments).where(active: true) ``` When I attempt to access the comments of the users, I sometimes get an behavior stating `ActiveRecord::RecordNotFound in UsersController#index`. This happens particularly when certain users don't have any posts or comments, and I don't want to filter them out. I've also tried wrapping the code in a `begin-rescue` block to handle the exception gracefully, but it seems like the scenario is arising during the loading phase itself, rather than during access. I checked my associations and they look correct: ```ruby class User < ApplicationRecord has_many :posts end class Post < ApplicationRecord belongs_to :user has_many :comments end class Comment < ApplicationRecord belongs_to :post end ``` I've confirmed that all foreign keys are set correctly and that the database is populated with the appropriate data. To debug further, I tried using `User.joins(posts: :comments).where(active: true).to_sql` to inspect the generated SQL, and it seems like the SQL is valid. Could this be an scenario related to how Rails is handling the eager loading in conjunction with missing associations? Are there any best practices or workarounds to avoid this behavior while still eager loading? Any insights would be appreciated! Any feedback is welcome! I'm on macOS using the latest version of Ruby.
