I want to pass the number of pages in a select box (10,15,25,50) and  
when I press some button or just doing the action (observer\_field?) it  
will change the pagination, how can i do it ?

Make the select box submit params[:per\_page] (name=“per\_page”)  
onChange. You’ll also want it to go back to the first page  
(params[:page] = 1) or else you could request an invalid page (e.g.,  
there is no page 7 at 50 items per page when you only have 100 items,  
even if you were on page 7 when viewing 10 items per page). Pass  
per\_page and page to the paginate call.
