At 9:43, you asked us to do our own show post fixes. I can't figure out how to fix it, checked your repo. Any right repo I can refer?

IDK if you are still wondering how to solve this. I noticed that if you open your terminal, there's a part in which indicates the possible path in which you need to make the modifications. In my case, indicated me that it was admin/show_post. I divided my @post from show_post to two variables as follow: @post = Post.includes(:user).find(params[:id]) @comments = Post.find(params[:id]).comments.includes(%i[user rich_text_body]) After those changes in my admin_controller, I needed to change one line in the views: from: to: It was mostly try and error tbh
