Bases: AssignmentDriverBase

add_role_to_user_and_project(user_id, project_id, role_id)

Add a role to a user within given project.

Raises:

keystone.exception.Conflict – If a duplicate role assignment exists.

check_grant_role_id(role_id, user_id=None, group_id=None, domain_id=None, project_id=None, inherited_to_projects=False)

Check an assignment/grant role id.

Raises:

keystone.exception.RoleAssignmentNotFound – If the role assignment doesn’t exist.

Returns:

None or raises an exception if grant not found

check_system_grant(role_id, actor_id, target_id, inherited)

Check if a user or group has a specific role on the system.

Parameters:

• role_id – the unique ID of the role to grant to the user

• actor_id – the unique ID of the user or group

• target_id – the unique ID or string representing the target

• inherited – a boolean denoting if the assignment is inherited or not

create_grant(role_id, user_id=None, group_id=None, domain_id=None, project_id=None, inherited_to_projects=False)

Create a new assignment/grant.

If the assignment is to a domain, then optionally it may be specified as inherited to owned projects (this requires the OS-INHERIT extension to be enabled).

create_system_grant(role_id, actor_id, target_id, assignment_type, inherited)

Grant a user or group a role on the system.

Parameters:

• role_id – the unique ID of the role to grant to the user

• actor_id – the unique ID of the user or group

• target_id – the unique ID or string representing the target

• assignment_type – a string describing the relationship of the assignment

• inherited – a boolean denoting if the assignment is inherited or not

classmethod default_role_driver()

delete_domain_assignments(domain_id)

Delete all assignments for a domain.

delete_grant(role_id, user_id=None, group_id=None, domain_id=None, project_id=None, inherited_to_projects=False)

Delete assignments/grants.

Raises:

keystone.exception.RoleAssignmentNotFound – If the role assignment doesn’t exist.

delete_group_assignments(group_id)

Delete all assignments for a group.

Raises:

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

delete_project_assignments(project_id)

Delete all assignments for a project.

Raises:

keystone.exception.ProjectNotFound – If the project doesn’t exist.

delete_role_assignments(role_id)

Delete all assignments for a role.

delete_system_grant(role_id, actor_id, target_id, inherited)

Remove a system assignment from a user or group.

Parameters:

• role_id – the unique ID of the role to grant to the user

• actor_id – the unique ID of the user or group

• target_id – the unique ID or string representing the target

• inherited – a boolean denoting if the assignment is inherited or not

delete_user_assignments(user_id)

Delete all assignments for a user.

Raises:

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

list_grant_role_ids(user_id=None, group_id=None, domain_id=None, project_id=None, inherited_to_projects=False)

List role ids for assignments/grants.

list_role_assignments(role_id=None, user_id=None, group_ids=None, domain_id=None, project_ids=None, inherited_to_projects=None)

Return a list of role assignments for actors on targets.

Available parameters represent values in which the returned role assignments attributes need to be filtered on.

list_system_grants(actor_id, target_id, assignment_type)

Return a list of all system assignments for a specific entity.

Parameters:

• actor_id – the unique ID of the actor

• target_id – the unique ID of the target

• assignment_type – the type of assignment to return

list_system_grants_by_role(role_id)

Return a list of system assignments associated to a role.

Override parent method with a simpler implementation.

RoleAssignment doesn’t have non-indexed ‘extra’ attributes, so the parent implementation is not applicable.
