ironic.objects.trait module¶

service None

Bases: ironic.objects.base.IronicObject

Trait.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.

classmethod Trait.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 Trait.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.

service None

classmethod TraitList.create(context, node_id, traits)[source]¶

Replace all existing traits with the specified list.

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. 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.

classmethod TraitList.destroy(context, node_id)[source]¶

Delete all traits for the specified node.

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.
Raises:	NodeNotFound if the node no longer appears in the database.

classmethod TraitList.get_by_node_id(context, node_id)[source]¶

Return all traits for the specified node.

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.
Raises:	NodeNotFound if the node no longer appears in the database.

TraitList.get_trait_names()[source]¶

Return a list of names of the traits in this list.
