I have a Persons table created with scaffold. I was trying to flick
between records by clicking on Previous and Next links. I was
struggling to understand will_paginate, and finally came up with
following solution, and I'm wondering if it could be done better.
Would it be better to have one query to a database returning previous
current and next record instead having two?
@person_previous = Person.paginate :all, :page => params[:page],
:order => 'id DESC', :per_page => 1, :conditions => "id <
#{params[:id]}"
@person_next = Person.paginate :all, :page => params[:page],
:order => 'id ASC', :per_page => 1, :conditions => "id >
#{params[:id]}"
<% @person_previous.each do |el|%>
<%= link_to 'Previous', el %>
<% end %>
<% @person_next.each do |el|%>
<%= link_to 'Next', el %>
<% end %>
