ROR Sample Application URL – http://sixrevisions.com/web-development/how-to-create-a-blog-from-scratch-using-ruby-on-rails/
I tried above reference for creating a blog application using Ruby on Rails.
Everything is working fine except the option “Add Comment” in show page of a Post.
As per the reference URL “Add Comment” will be there in Show page itself. But in my local browser I am not able to see it.
Note : I am using Rails 3.1.3 with back end of PostgreSQL 9.0.5
You have probably missed something in the code (obvious, I know), I would suggest rolling back to a working model without comments and following the guide from there.
This guide is a copy of the sample blog guide found at http://guides.rubyonrails.org/getting_started.html so I would suggest following the official guide as it probably explains in more detail and covers topics based on community feedback. I have found these guides to be the most up-to-date resource for rails on the web.
