find method or something..then where should i write the code? in item
controller ?then how can i call it from my listing items ?somebody
help me pls.........

If you are using rails 2.1 then you can use a named scope on the Item
model like such

== in Item
belongs_to :category
named_scope :same_category, :include => :category, :conditions =>
{ 'category.name' => category.name }
then you can do

== IteamsController (i suppose)
def edit
  @iteams = Item.same_category
  @item = ...
end

and it will do the find for you.
