Web UI restrictions doesn't work correcly for Ironic

This bug is blocker for MOS-QA Team
On SI we got Error:

2016-04-20 22:16:35,468 - ERROR http.py:110 -- Bad Request code 400 [{"message": "Some restrictions didn't pass verification: [\"Validation failed for attribute 'Install Ironic': Ironic requires Swift or RadosGW for Glance images.\"]", "errors": []}]

Actually radosgw is not required for using Ceph as images and volumes backend

> 'Install Ironic': Ironic requires Swift or RadosGW for Glance images.

radosgw is an optional component of a ceph cluster, quite a number of installations don't use radosgw at all
(they use ceph mainly via rbd to provide the storage for VMs). Therefore whatever deploys Ironic should explicitly enable radosgw (and adjust settings according to Ironic requirements)

As a work around one can manually enable radosgw (in Fuel UI: Settings -> Storage -> Ceph RadosGW for objects (Swift API))

The following restriction doesn't work on UI. Please have look at the attachment.

Please clarify if you need some work done on the Ironic side, it's not quite obvious at first glance.

Vasyl, thank you for the video recording. It perfectly demonstrates the bug.

The issue is that user is able to turn on Ironic in the wizard when Ceph for objects (Rados GW) is off: http://s32.postimg.org/h4y4vyttx/wizard_storage.png and http://s32.postimg.org/94xmcph1h/wizard_services.png

If user does not enable Ironic from the wizard, it is impossible to do on Settings tab: http://s32.postimg.org/6u00rwn7p/storage_tab.png and http://s32.postimg.org/jph765h8l/services_tab.png
That's an expected behaviour.

So, we need to fix restrictions for Ironic in wizard to require Ceph for objects (Rados GW) to be enabled.

Fix proposed to branch: master

Let me explain how wizard tab working. It operates in terms of compatible/incompatible not restrictions and hasn't condition operator for now (some improvements will be in 10.0 https://blueprints.launchpad.net/fuel/+spec/component-registry-improvements). Settings page has more deep level of validation and it's expected behavior to raise validation message for restriction. As was written above possible workaround is just enable one option on settings tab. I agree that wizard should more smart but currently I don't see it as critical blocker for deployment so change priority to medium.

This was opened over a year ago, and after reading the comments, it isn't clear to me that this is an ironic issue, so I'm going to invalidate it. If you have more information, please comment and update the status. Thanks.
