Question

I\'m new in Rails... smile

In my blog aplication I want to have a \"Previous post\" link and a \"Next post\" link in the bottom of my show view.

How do I do

I've created gem proximal_records especially for this kind of task and it works on any dynamically created scope in your model.

https://github.com/dmitry/proximal_records

Basic example:

class Article < ActiveRecord::Base
  include ProximalRecords
end


scope = Article.title_like('proximal').order('created_at DESC, title ASC')
current_record = scope.to_a[5]
p, n = current_record.proximal_records(scope) # will find record 5 and 7
