Will Paginate Condition In Rails 3

will paginate di rails 3 memiliki beberapa perbedaan, jika di rails 2 "paginate" hampir sama dengan "find", tetapi di rails 3 berbeda.

Contoh Script:

conditions = ["condition what!"]
order_by = ["order by what!"]
a = current_user.a

for rails 2:

@A = a.paginate(:page => params[:page], :per_page => @per_page, :conditions => conditions, :order => order_by)

for rails 3:

a = current_user.a
@A = a.find(:all, :conditions => conditions, :order => order_by).paginate(:page => params[:page], :per_page => @per_page)

jika condition atau order tidak dibuat variabel terpisah maka kita bisa menggunakan where atau order sesuai ketentuan di rails 3
