OK, I actually cheat a little in the controller and have the delete
call the destroy method. I really didn't want the "are you sure"
prompt, so this seems to work fine from a link_to('delete',
resource(obj, :delete))
def destroy
if get_resource.destroy
redirect resource(controller_name.to_sym)
else
raise InternalServerError
end
end
def delete(id)
destroy
end
Have fun,
Roy
