[Bug 2011998] Re: [SRU] Flavor: Not Available on Instance View

[Heitor Alves de Siqueira]

Thanks for the patches, Rodrigo! Your debdiff has some cruft in it, but
the actual patches look good. Given Focal is almost EOL, it'd be great
if we could get this tested as soon as it hits proposed.

Bug description:
  ************* SRU TEMPLATE AT THE BOTTOM ************

  OpenStack/Horizon: Yoga

  After creating an instance

  # openstack server show test2 | egrep 'flavor| id '
  | flavor                              | gen.medium (gen.medium)
  | id                                  | 95ce0962-64b2-4e38-9af7-af2932c9f192
  # openstack flavor show gen.medium | grep flavor-access
  | os-flavor-access:is_public | True

  In Horizon:
  This flavor is shown on (Instances) view for the project as both Admin/User correctly (/project/instances/):

  Instance Name	Image Name	     IP Address	   Flavor	Key Pair	Status		Availability Zone
  test2	        Ubuntu 22.04 (Jammy) 192.168.0.237 gen.medium	key1	        Active		nova	None	Running	22 minutes

  However when going to the Instance detail view (/project/instances/95ce0962-64b2-4e38-9af7-af2932c9f192/)
  The Specs category shows:

  Specs
  Flavor Not available

  Let me know if any additional info can be provided to assist with troubleshooting.
  Patches from https://bugs.launchpad.net/horizon/+bug/1940834 appear to already be present.
  This appears to be mainly a visual/cosmetic issue in Instance detail view.

  ===============
  SRU DESCRIPTION
  ===============

  [Impact]

  The instance detail page will not display flavor information about a
  specific instance. This issue affects the user experience when trying
  to see the flavor information of an instance through the dashboard.
  The flavor name can still be seen in the instance list though.

  [Test case]

  1. Deploy openstack with dashboard

  2. login and create an instance

  3. check that the instance is displayed in the list and the correct
  flavor is displayed

  4. click the instance to open the instance detail page, and check that
  the flavor field says "not available"

  5. install the fixed package

  6. reload the dashboard and navigate to the instance detail page
  again, the flavor field should show the correct flavor now

  [Where problems could occur]

  The code only modifies the instance detail page, so if there is any
  problem with the modification, the instance page detail page will fail
  to load. The package will have to be reverted to restore the previous
  functionality.

  [Other Info]

  None
