Routing through parent

You can do that with map.connect ‘:category_name/:product_name’, :controller => <controller_name>, :action => <action_name>

You’ll have to think about how good an idea it is to use only category and product names and not ids

Think about using to_param on your models which can then display both id and name
class Category < ActiveRecord::Base
def to_param
“#{id}-#{name.gsub(/[^\w\d]+/, ‘-’)}”


Then you don’t have to mess with your routes and your urls will be /1-category/2-product and your controllers will still get the id in params[:id]
