Title:
GET details REST API next link missing 'details'
Status in Cinder:
Fix Released
Status in Cinder icehouse series:
Fix Released
Status in OpenStack Compute (nova):
Fix Released
Bug description:
When executing a pagination query a "next" link is included in the API
reply when there are more items then the specified limit.
See pagination documentation for more information:
http://docs.openstack.org/api/openstack-compute/2/content
/Paginated_Collections-d1e664.html
The caller should be able to invoke the "next" link (without having to
re-format it) in order to get the next page of data. The
documentation states "Subsequent links will honor the initial page
size. Thus, a client may follow links to traverse a paginated
collection without having to input the marker parameter."
The problem is that the "next" link is always scoped to the non-
detailed query. For example, if you execute
"/v2/<tenant>/servers/detail?limit=1", the "next" link does not have
the URL for a detailed query and is formatted as
"/v2/<tenant>/servers?limit=1&marker=<marker>". In this case the
"next" link needs to be scoped to "/v2/<tenant>/servers/detail".
This bug is caused because the "next" link is always generated by the
_collection_name value in the ViewBuilder -- this name is always
"servers".
