Bases: object

create_implied_role(prior_role_id, implied_role_id)

Create a role inference rule.

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

create_role(role_id, role)

Create a new role.

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

delete_implied_role(prior_role_id, implied_role_id)

Delete a role inference rule.

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

delete_role(role_id)

Delete an existing role.

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

get_implied_role(prior_role_id, implied_role_id)

Get a role inference rule.

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

get_role(role_id)

Get a role by ID.

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

list_implied_roles(prior_role_id)

List roles implied from the prior role ID.

list_role_inference_rules()

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

list_roles(hints)

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)

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)

Update an existing role.

Raises:

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