How to handle conditional callbacks in Rails 7 models based on associated records?
I'm working on a personal project and I'm working on a Ruby on Rails 7 application where I need to implement conditional callbacks in my models based on the state of associated records. The main scenario arises when I want to trigger a callback only if a certain condition on an associated model is met. For example, I have a `Post` model that has many `Comments`. I want to ensure that before a post is destroyed, I only perform some cleanup if the post has no approved comments. Here's what I've tried so far: ```ruby class Post < ApplicationRecord has_many :comments before_destroy :cleanup_if_no_approved_comments private def cleanup_if_no_approved_comments if comments.approved.empty? # Perform cleanup actions puts 'Cleaning up resources...' else throw(:abort) # Prevent destruction due to approved comments end end end class Comment < ApplicationRecord belongs_to :post scope :approved, -> { where(approved: true) } end ``` However, I'm working with an scenario where the `before_destroy` callback seems to be getting called even when there are approved comments, and the post is still being destroyed. The behavior message I see in the logs is: ``` ActiveRecord::RecordNotSaved: Failed to save the record: - Validation failed: Approved comments exist. ``` It seems like the callback is not working as expected, or maybe there's a misunderstanding about how to use `throw(:abort)`. I've also considered using `before_validation` instead, but that doesn't seem to fit my needs. Is there a better way to achieve this conditional callback for post destruction? Any insights or best practices would be greatly appreciated. This is for a REST API running on Debian.
