ActiveRecord Queries Returning Object IDs Instead of Model Objects in Rails 6
I can't seem to get I'm attempting to set up I'm working on a project and hit a roadblock... I'm working with a strange scenario with my Rails 6 application where a method intended to return model objects is instead returning an array of object IDs. For instance, I have a method that fetches associated records using `includes` to avoid N+1 queries: ```ruby class Post < ApplicationRecord has_many :comments end class Comment < ApplicationRecord belongs_to :post end class PostsController < ApplicationController def index @posts = Post.includes(:comments).all end end ``` However, when I try to access the comments in the view, like this: ```erb <% @posts.each do |post| %> <h2><%= post.title %></h2> <ul> <% post.comments.each do |comment| %> <li><%= comment.body %></li> <% end %> </ul> <% end %> ``` I am getting this behavior message: `undefined method 'body' for Integer:Class`. It seems that `post.comments` is returning an array of comment IDs instead of actual comment objects. I've double-checked the `Post` and `Comment` model definitions, and they seem fine. I also verified the database schema and it looks correct. I've tried using `post.comments.to_a` and `post.comments.includes(:post)`, but those did not resolve the scenario. Am I missing something in the `includes` usage or is there another reason why I'm not getting the ActiveRecord objects? Any insights would be appreciated! I'm working on a web app that needs to handle this. What would be the recommended way to handle this? Is there a better approach?
