Hi  
Below is the code for controller service\_desk show action(some  
portion only)  
def show  
@sd\_attachments=service\_desk\_ticket.service\_desk\_attachments.paginate  
:page =\> params[:page], :per\_page =\> 15  
@sd\_activities=ServiceDeskActivity.find\_all\_by\_service\_desk\_ticket\_id(service\_desk\_ticket.id)paginate  
:page =\> params[:page], :per\_page =\> 15

end

```
HERE THE show.rhtml contains differnt tabs like

```

Attachments,Activities etc…  
And I use Ajax for pagination in all these tabs…Suppose for example  
sd\_attachments first show say 15 attachments, then to get next 15, I  
again have to write the same pagination code as in show for this  
sd\_attachments in the controller…(In another file)And by using RJS  
replacing the div (The sd\_attachment is complete inside a div)…BUT THE  
PROBLEM IS EVEN IF THE CODE FOR PAGINATION IS THERE IN show ACTION I  
HAVE TO WRITE IT AGAIN AND AGAIN FOR EACH TAB…HOW CAN I AVOID THIS.?
