I want to use hierarchical url for my application.How can i create?How must i save database in slug field?As like parent/parent/productname (such as catch-all) or only productname?

For example my database hierarchy as follow,

     |--> Electronics
             |
             |--> Television
                       |
                       |--> Led Tv
                       |--> Lcd Tv
                       |--> Plasma

i want to create hierarchical url such as http://www.domain.com/products/electronics/television/led_tv

The link you posted does not take you to a working page (page not found-404).

What exactly are you trying to do?
