Submodules¶

keystone.resource.backends.base module¶

class keystone.resource.backends.base.ResourceDriverBase[source]¶

Bases: object

create_project(project_id, project)[source]¶

Create a new project.

Parameters:	project_id – This parameter can be ignored. project (dict) – The new project

Project schema:

type: object
properties:
    id:
        type: string
    name:
        type: string
    domain_id:
        type: [string, null]
    description:
        type: string
    enabled:
        type: boolean
    parent_id:
        type: string
    is_domain:
        type: boolean
required: [id, name, domain_id]
additionalProperties: true

If the project doesn’t match the schema the behavior is undefined.

The driver can impose requirements such as the maximum length of a field. If these requirements are not met the behavior is undefined.

Raises:	keystone.exception.Conflict – if the project id already exists or the name already exists for the domain_id.

delete_project(project_id)[source]¶

Delete an existing project.

Raises:	keystone.exception.ProjectNotFound – if project_id does not exist

delete_projects_from_ids(project_ids)[source]¶

Delete a given list of projects.

Deletes a list of projects. Ensures no project on the list exists after it is successfully called. If an empty list is provided, the it is silently ignored. In addition, if a project ID in the list of project_ids is not found in the backend, no exception is raised, but a message is logged.

get_project(project_id)[source]¶

Get a project by ID.

Returns:	project_ref
Raises:	keystone.exception.ProjectNotFound – if project_id does not exist

get_project_by_name(project_name, domain_id)[source]¶

Get a project by name.

Returns:	project_ref
Raises:	keystone.exception.ProjectNotFound – if a project with the project_name does not exist within the domain

is_leaf_project(project_id)[source]¶

Check if a project is a leaf in the hierarchy.

Parameters:	project_id – the driver will check if this project is a leaf in the hierarchy.
Raises:	keystone.exception.ProjectNotFound – if project_id does not exist

list_project_ids_from_domain_ids(domain_ids)[source]¶

List project ids for the provided list of domain ids.

Parameters:	domain_ids – list of domain ids
Returns:	a list of project ids owned by the specified domain ids.

This method is used internally by the assignment manager to bulk read a set of project ids given a list of domain ids.

list_project_parents(project_id)[source]¶

List all parents from a project by its ID.

Parameters:	project_id – the driver will list the parents of this project.
Returns:	a list of project_refs or an empty list.
Raises:	keystone.exception.ProjectNotFound – if project_id does not exist

list_projects(hints)[source]¶

List projects in the system.

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

list_projects_acting_as_domain(hints)[source]¶

List all projects acting as domains.

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

list_projects_from_ids(project_ids)[source]¶

List projects for the provided list of ids.

Parameters:	project_ids – list of ids
Returns:	a list of project_refs.

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

list_projects_in_domain(domain_id)[source]¶

List projects in the domain.

Parameters:	domain_id – the driver MUST only return projects within this domain.
Returns:	a list of project_refs or an empty list.

list_projects_in_subtree(project_id)[source]¶

List all projects in the subtree of a given project.

Parameters:	project_id – the driver will get the subtree under this project.
Returns:	a list of project_refs or an empty list
Raises:	keystone.exception.ProjectNotFound – if project_id does not exist

update_project(project_id, project)[source]¶

Update an existing project.

Raises:	keystone.exception.ProjectNotFound – if project_id does not exist keystone.exception.Conflict – if project name already exists

keystone.resource.backends.base.get_project_from_domain(domain_ref)[source]¶

Create a project ref from the provided domain ref.
