Unexpected `before_action` callback order in Rails 7 with nested controllers
I'm following best practices but I've been struggling with this for a few days now and could really use some help. I'm relatively new to this, so bear with me. I'm encountering an issue with the order of `before_action` callbacks in my Rails 7 application. I have a nested resource setup where I'm trying to enforce authorization checks before certain actions in my `PostsController` and `CommentsController`. However, the callbacks seem to be executed in an unexpected order, resulting in unauthorized access to certain actions. Here's a simplified version of my controllers: ```ruby class PostsController < ApplicationController before_action :authenticate_user!, only: [:create, :update] before_action :set_post, only: [:show, :update, :destroy] def create # Creating post logic end def update # Updating post logic end private def set_post @post = Post.find(params[:id]) end end class CommentsController < ApplicationController before_action :authenticate_user!, only: [:create] before_action :set_post before_action :set_comment, only: [:update, :destroy] def create # Creating comment logic end def update # Updating comment logic end private def set_post @post = Post.find(params[:post_id]) end def set_comment @comment = @post.comments.find(params[:id]) end end ``` When I try to create a comment for a post, I expect the `authenticate_user!` method to be called before any action in the `CommentsController`. However, it seems like the `set_post` method is called first, allowing unauthorized access to the comments of posts. I receive the following error when accessing a comment without authorization: ``` ActiveRecord::RecordNotFound: Couldn't find Comment with 'id'=#{params[:id]} for Post with 'id'=#{params[:post_id]} ``` I've double-checked the routes and made sure that the nested resource routes are defined correctly. It looks like this: ```ruby resources :posts do resources :comments end ``` I've also tried to rearrange the order of the callbacks in the `CommentsController`, but the behavior remains the same. Is there a specific reason why `set_post` is executed before `authenticate_user!`, or is there a best practice for handling this kind of situation in Rails? Any insights or suggestions would be greatly appreciated! Thanks in advance! My development environment is Windows 10. I'm working in a Debian environment. I've been using Ruby for about a year now.
