ironic.objects.trait module

class ironic.objects.trait.Trait(context=None, **kwargs)

Bases: IronicObject

VERSION = '1.0'

create(context=None)

Create a Trait record in the DB.

Parameters:

context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Trait(context).

Raises:

InvalidParameterValue if adding the trait would exceed the per-node traits limit.

Raises:

NodeNotFound if the node no longer appears in the database.

property created_at

dbapi = <oslo_db.api.DBAPI object>

classmethod destroy(context, node_id, trait)

Delete the Trait from the DB.

Parameters:

• context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Trait(context).

• node_id – The id of a node.

• trait – A trait string.

Raises:

NodeNotFound if the node no longer appears in the database.

Raises:

NodeTraitNotFound if the trait is not found.

classmethod exists(context, node_id, trait)

Check whether a Trait exists in the DB.

Parameters:

• context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Trait(context).

• node_id – The id of a node.

• trait – A trait string.

Returns:

True if the trait exists otherwise False.

Raises:

NodeNotFound if the node no longer appears in the database.

class ironic.objects.trait.TraitList(*args, **kwargs)

Bases: IronicObjectListBase, IronicObject

VERSION = '1.0'

classmethod create(context, node_id, traits)

Replace all existing traits with the specified list.

Parameters:

• node_id – The id of a node.

• traits – List of Strings; traits to set.

Raises:

InvalidParameterValue if adding the trait would exceed the per-node traits limit.

Raises:

NodeNotFound if the node no longer appears in the database.

property created_at

dbapi = <oslo_db.api.DBAPI object>

classmethod destroy(context, node_id)
