alias of cinder.db.sqlalchemy.models.VolumeType

property 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 an object representation compatible with a target version.

This is responsible for taking the primitive representation of an object and making it suitable for the given target_version. This may mean converting the format of object attributes, removing attributes that have been added since the target version, etc. In general:

  • If a new version of an object adds a field, this routine should remove it for older versions.

  • If a new version changed or restricted the format of a field, this should convert it back to something a client knowing only of the older version will tolerate.

  • If an object that this object depends on is bumped, then this object should also take a version bump. Then, this routine should backlevel the dependent object (by calling its obj_make_compatible()) if the requested version of this object is older than the version where the new dependent object was added.

Parameters

  • primitive – The result of obj_to_primitive()

  • target_version – The version string requested by the recipient of the object

Raises

oslo_versionedobjects.exception.UnsupportedObjectError if conversion is not possible for some reason

property projects
property qos_specs
property qos_specs_id
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.
