Question

I have a rails application in which pages has many comments. So the relationships in the models are:

page.rb: has_many :comments

comment.rb: belongs_to :page

Now I display the comments in my view by doing:

<% @page.comments.each_with_index do |comment| %>
   <%= comment.comment %>
<%end%>

I want to know how I can paginate this with will_paginate. I also want to make it so that the newest one (one with greatest id shows up first). Any ideas?

Answer 1

To order the comments:

has_many :comments, :order => "id DESC"

To use will_paginate just push the logic into your controller:

@comments = @page.comments.paginate(:page => params[:page])
