class keystone.assignment.role_backends.base.RoleDriverBase[source]¶

Bases: object

create_implied_role(prior_role_id, implied_role_id)[source]¶

Create a role inference rule.

Raises:	keystone.exception.RoleNotFound: If the role doesn’t exist.

create_role(role_id, role)[source]¶

Create a new role.

Raises:	keystone.exception.Conflict – If a duplicate role exists.

delete_implied_role(prior_role_id, implied_role_id)[source]¶

Delete a role inference rule.

Raises:	keystone.exception.ImpliedRoleNotFound – If the implied role doesn’t exist.

delete_role(role_id)[source]¶

Delete an existing role.

Raises:	keystone.exception.RoleNotFound – If the role doesn’t exist.

get_implied_role(prior_role_id, implied_role_id)[source]¶

Get a role inference rule.

Raises:	keystone.exception.ImpliedRoleNotFound – If the implied role doesn’t exist.

get_role(role_id)[source]¶

Get a role by ID.

Returns:	role_ref
Raises:	keystone.exception.RoleNotFound – If the role doesn’t exist.

list_implied_roles(prior_role_id)[source]¶

List roles implied from the prior role ID.

list_role_inference_rules()[source]¶

List all the rules used to imply one role from another.

list_roles(hints)[source]¶

List roles in the system.

Parameters:	hints – filter hints which the driver should implement if at all possible.
Returns:	a list of role_refs or an empty list.

list_roles_from_ids(role_ids)[source]¶

List roles for the provided list of ids.

Parameters:	role_ids – list of ids
Returns:	a list of role_refs.

This method is used internally by the assignment manager to bulk read a set of roles given their ids.

update_role(role_id, role)[source]¶

Update an existing role.

Raises:	keystone.exception.RoleNotFound – If the role doesn’t exist. keystone.exception.Conflict – If a duplicate role exists.
