Question

Say if I have a set of objects contained in @set. Each of these objects has a description method which will return some text that I want to display on individual pages. How do I use will_paginate to paginate this?

The examples I’ve seen so far such as:

@articles = Article.paginate :page => params[:page]  

look like they are referring to all Article objects.

Assuming your model is called SomeObject, the will_paginate syntax is similar to that of ActiveRecord’s .find():

@set = SomeObject.paginate(:page       => params[:page],                            :per_page   => 20,                            :order      => 'created_at DESC',                            :conditions => { :foo => 'bar' })
