ruby-on-rails activerecord callbacks ruby

I've spent hours debugging this and I'm not sure how to approach This might be a silly question, but This might be a silly question, but I'm working with an scenario with ActiveRecord callbacks in my Rails 7.1 application... I have a model `Project` that has many `Tasks`, and I'm using the `dependent: :destroy` option to automatically delete associated tasks when a project is deleted. However, I'm noticing that the `before_destroy` callback in the `Task` model is not being triggered as expected. Here is my `Project` model: ```ruby class Project < ApplicationRecord has_many :tasks, dependent: :destroy end ``` And my `Task` model: ```ruby class Task < ApplicationRecord belongs_to :project before_destroy :log_removal private def log_removal Rails.logger.info "Task #{id} is being removed" end end ``` When I delete a project like this: ```ruby project = Project.find(1) project.destroy ``` I check the logs, but I don't see any log entries indicating that `log_removal` was called. The associated tasks are being deleted, but I need to run some cleanup logic in that callback. I've verified that the `before_destroy` callback works when I delete a `Task` instance directly, so I'm unsure why it's not firing during the `Project` deletion. I've also checked if there are any other callbacks that might interfere, but I'm not seeing anything that stands out. Is there something specific about how `dependent: :destroy` works that might be causing this scenario? Any insights would be greatly appreciated! For context: I'm using Ruby on Linux. How would you solve this? Any help would be greatly appreciated! This is my first time working with Ruby 3.11. Any examples would be super helpful. I recently upgraded to Ruby 3.9. Thanks for any help you can provide!
