property group_snapshot
property group_snapshot_id
property host

All cleanable VO must have a host property/attribute.

property id
property metadata
model

alias of Snapshot

property name
obj_extra_fields = ['name', 'volume_name']
obj_load_attr(attrname)

Load an additional attribute from the real object.

This should load self.$attrname and cache any data that might be useful for future load operations.

obj_make_compatible(primitive, target_version)

Make a Snapshot representation compatible with a target version.

obj_reset_changes(fields=None)

Reset the list of fields that have been changed.

Parameters:
  • fields – List of fields to reset, or “all” if None.

  • recursive – Call obj_reset_changes(recursive=True) on any sub-objects within the list of fields being reset.

This is NOT “revert to previous values”.

Specifying fields on recursive resets will only be honored at the top level. Everything below the top will reset all.

obj_what_changed()

Returns a set of fields that have been modified.

property progress
property project_id
property provider_auth
property provider_id
property provider_location
save()

Save the changed fields back to the store.

This is optional for subclasses, but is presented here in the base class for consistency among those that do.

class SnapshotList(*args, **kwargs)

classmethod get_all(context, filters, marker=None, limit=None, sort_keys=None, sort_dirs=None, offset=None)

Get all snapshot given some search_opts (filters).

Special filters accepted are host and cluster_name, that refer to the volume’s fields.
