Hi Daniel,
I think this will solve this problem
if i have a boolean field in my model and if I would like to display
only if that fileld id true to the non-super users and otherwise
always show the boolean field.
But my question was
how to disable the select all widget from the admin panel if the user
is non-super user. The select all widget helps in selecting all the
objects but since my action is empty, i dont want to show any widget.
Also, I am not sure why we need this as well
def change_view(self, request, object_id, extra_context=None):
if Part.objects.get(id=object_id).is_deleted==True and
request.user.is_superuser == False:
return HttpResponseRedirect('/admin/')
else:
return super(PartAdmin, self).change_view(request,
object_id,extra_context=None)
Thanks.
