that’s all to it. if you can start script/server and get no errors for  
it, it should be ok so far.

to actually paginate something do this (example for model named  
Product):

@products = Product.paginate(:all, :order =\> “products.created\_at  
DESC”,  
:page =\>  
params[:page].to\_i, :per\_page =\> params[:per\_page].to\_i)

mind, that params[:page] & params[:per\_page] should be initialized  
properly  
per\_page should be 1 for first call and set to other pages for further  
calls. but will\_paginate will  
handle most of it.

in the view you get the pagination links like that:  
\<% unless @products.nil? or @products.empty?%\>  
\<%= will\_paginate @products, :inner\_window =\> 2 %\>  
\<% else %\>  
found nothing  
\<% end %\>

Classic pagination has been moved into a plugin since 2.0.
