post_save_redirect in update_object generic view

In "update_object" generic view, I want to go back to the object_detail page whose URL is like /app/obj//, after the update operation. How do I specify post_save_redirect to do that?

upload to user directory

I'm having trouble trying to set the upload_to path for a filefield that will contain the user's id or username - "images/%s" % User.username obviously doesn't work, but it's exactly what I'm trying to do... can I set the upload path dynamically somehow? Luke Skibinski Holt
