Rails 7.1: solution with ActiveRecord associations loading optimization correctly in a polymorphic relationship
I'm a bit lost with I'm integrating two systems and I'm working through a tutorial and After trying multiple solutions online, I still can't figure this out. This might be a silly question, but I'm working with an scenario with a polymorphic association in my Rails 7.1 application... I have a `Comment` model that can belong to either a `Post` or an `Image`. The association is set up like this: ```ruby class Comment < ApplicationRecord belongs_to :commentable, polymorphic: true end class Post < ApplicationRecord has_many :comments, as: :commentable end class Image < ApplicationRecord has_many :comments, as: :commentable end ``` I'm trying to retrieve comments for a post, but I notice that the comments are not loading as expected. Here's the code I'm using to fetch comments: ```ruby post = Post.find(params[:id]) @comments = post.comments ``` When I check the output, `@comments` returns an empty array, even though I know there are comments associated with the post. I've verified that the records exist in the database with the correct `commentable_id` and `commentable_type`. To troubleshoot, I did the following: 1. Confirmed that comments exist in `comments` table with the correct `commentable_id` and `commentable_type` (both equal to the post ID and 'Post'). 2. Ensured that there are no scopes applied that might be filtering out the results unintentionally. 3. Used `rails console` to manually query comments using `Comment.where(commentable: post)` and this returns the expected comments. Could there be some configuration or caching scenario that affects how Rails retrieves the associated comments in this context? I've also checked for any relevant database constraints that could prevent the association from loading correctly, but everything looks good on that end. Any insights into what might be causing this scenario would be greatly appreciated! What's the best practice here? My development environment is macOS. Has anyone else encountered this? How would you solve this? How would you solve this? I'm working with Ruby in a Docker container on Ubuntu 20.04. Any pointers in the right direction? My team is using Ruby for this web app. What's the correct way to implement this?
