I am having trouble with learning to use httpresponseredirect and
reverse.
I am trying to generate an admin action on a selection of a list of
items. The purpose is to generate an intermediate window that can be
used to select a new
status for all the objects,
The admin action shows up in the pulldown menu on /admin/items/item.
However, once clicked, I get the following error: NoReverseMatch at /
admin/items/item/
Any advice would be greatly appreciated, I have been pounding me head
for a day or so on this. I am certainly a novice, so this is likely
to be a very newbie misunderstanding.
Many thanks,
Guy
