Title:
  Horizon crashed when parsing volume list including a volume without
  name

Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in OpenStack Dashboard (Horizon) juno series:
  In Progress

Bug description:
  This bug can be re-produced as follows:
   - 1. Use Nova or Cinder CLI to create a volume without name that can be used to boot a new VM:

  nova boot some_name --flavor 1 --image some_img_id --nic net-
  id=some_nic_id  --block-device
  source=image,id=some_img_id,dest=volume,size=1,bootindex=1"

         Note that: in the "--block-device", we don't specify volume
  name

  
  cinder create 1 --image-id some_img_id

         Note that: we don't specify name for the volume to be created

  
   - 2. After that, if we try to retrieve the volume list by clicking the tab "Volumes" on Horizon, then Horizon will always be crashed. Note that, the crash does not occur when using CLI "cinder list" to list all available volumes.

  140421861299968] KeyError: 'device'

  Root cause: from the above Traceback, it's easy to see that the crash
  root cause is because Horizon tries to get the value of a non-existing
  key.

  Proposal for fixing this bug: secure the accessing the key "device" as follows:
         "dev": html.escape(attachment.get("device", ""))}
