To set a class wide Default
class Post < ActiveRecord::Base
def self.per_page
25
end
end
Or on a query by query basis use the per_page in your call
class Post <ActiveRecord::Base
def self.posts_by_paginate
paginate(:all, :per_page => 25, :conditions => ["published = ?", true])
end
end
Shameless self blog post.. but see if it helps

Here is what I will do
Class UsersController < ApplicationController
def index
@users = User.paginate(:all, :page => params[:page], :per_page => params[:number_of_records])
end
end
Looks like the OP also asked here: http://railsforum.com/viewtopic.php?id=33793 and got much better answers.
To adapt the best solution there, here's what I like:
(in the view)
<%= select_tag :per_page, options_for_select([10,20,50], params[:per_page].to_i),
:onchange => "if(this.value){window.location='?per_page='+this.value;}" %>
(in the controller)
@per_page = params[:per_page] || Post.per_page || 20
@posts = Post.paginate( :per_page => @per_page, :page => params[:page])
