‘will_paginate‘ is one of the most widely used plugins in most of the ruby on rails projects.will_paginate is an alternative to the classic_pagination plugin, which is the pagination plugin that basically took the pre Rails 2.0 pagination implementation and packaged it in plugin form
1.How to Install will_paginate
the simple method
gem install mislav-will_paginate

There are some other method you can find it here.

2.Example

In controller
@gallery=Gallery.find(:all,:order=>”position asc”).paginate :page => page,:per_page=>10

where :per_page passes the number of gallery you want to display.You can change it according to your need 1-100
will_paginate defines it to be 30 by default

In View

you can simply use

<%= will_paginate @gallery %>
some advanced …

<% if @gallery.previous_page %>
<%= will_paginate @gallery,:page_links=>false, :next_label => “”, :prev_label => image_tag(“/images/icon/arrow.png”, :border => “0″) %>
<% end %>

<% if @gallery.next_page %>
<%= will_paginate @gallery,:page_links=>false, :next_label => image_tag(“/images/icon/arrow.png”,, :border => “0″), :prev_label => “” %>
<% end %>

If we put page_links=>false then it won’t display 1,2,3… and next_label and prev_label => “” as null it won’t display Next and Prev
