1.8b3 Zones on "zone" page doesn't match zones on "node listing"

[Carla Berkers]

In MAAS 1.8b3, I have three zones in my "Zones" page, but when I go to node listing, I can only filter by the default zone.

As a result, if I click on the number of machines in my "Zones" page, I go to the node listing page but don't see any machines for the zone filter.

That is by design. We only show the zones that nodes belong to on the nodes listing page. I don't think this should change and changing this would be a major overhaul of how filtering is shown.

There is nothing wrong with going to the nodes listing and not seeing any nodes, if no nodes exist for that zone.

Agreed we should only show zones that have nodes assigned to them in the listing. If a zone has no nodes assigned, the "0" in the table should not be a hyperlink.

However in this case I click on the 1 node hyperlink in the table on the zones page and it takes me to node listings which shows me no machines in that zone. This can't be right.
Just filed another bug, perhaps this is just a consequence of

We should just make the link for viewing the nodes in a zone only available if nodes exist in that zone. Otherwise it should just be a 0 not in a hyperlink.
