Usage examples
## perform a paginated query:
@posts = Post.paginate(:page => params[:page])
# or, use an explicit "per page" limit:
Post.paginate(:page => params[:page], :per_page => 30)
## render page links in the view:
<%= will_paginate @posts %>
# for the Post model
class Post
self.per_page = 10
end
# set per_page globally
WillPaginate.per_page = 10
New in Active Record 3
# paginate in Active Record now returns a Relation
Post.where(:published => true).paginate(:page => params[:page]).order('id DESC')
# the new, shorter page() method
Post.page(params[:page]).order('created_at DESC')
