class airflow.providers.fab.auth_manager.fab_auth_manager.FabAuthManager(appbuilder)[source]

Bases: airflow.auth.managers.base_auth_manager.BaseAuthManager

Flask-AppBuilder auth manager.

This auth manager is responsible for providing a backward compatible user management experience to users.

static get_cli_commands()[source]

Vends CLI commands to be included in Airflow CLI.

get_api_endpoints()[source]

Return API endpoint(s) definition for the auth manager.

get_user_display_name()[source]

Return the user’s display name associated to the user in session.

get_user()[source]

Return the user associated to the user in session.

init()[source]

Run operations when Airflow is initializing.

is_logged_in()[source]

Return whether the user is logged in.

is_authorized_configuration(*, method, details=None, user=None)[source]

Return whether the user is authorized to perform a given action on configuration.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – the method to perform

  • details (airflow.auth.managers.models.resource_details.ConfigurationDetails | None) – optional details about the configuration

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_connection(*, method, details=None, user=None)[source]

Return whether the user is authorized to perform a given action on a connection.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – the method to perform

  • details (airflow.auth.managers.models.resource_details.ConnectionDetails | None) – optional details about the connection

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_dag(*, method, access_entity=None, details=None, user=None)[source]

Return whether the user is authorized to access the dag.

There are multiple scenarios:

1. dag_access is not provided which means the user wants to access the DAG itself and not a sub entity (e.g. DAG runs). 2. dag_access is provided which means the user wants to access a sub entity of the DAG (e.g. DAG runs).

  1. If method is GET, then check the user has READ permissions on the DAG and the sub entity.

  2. Else, check the user has EDIT permissions on the DAG and method on the sub entity. However,

    if no specific DAG is targeted, just check the sub entity.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – The method to authorize.

  • access_entity (airflow.auth.managers.models.resource_details.DagAccessEntity | None) – The dag access entity.

  • details (airflow.auth.managers.models.resource_details.DagDetails | None) – The dag details.

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – The user.

is_authorized_dataset(*, method, details=None, user=None)[source]

Return whether the user is authorized to perform a given action on a dataset.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – the method to perform

  • details (airflow.auth.managers.models.resource_details.DatasetDetails | None) – optional details about the dataset

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_pool(*, method, details=None, user=None)[source]

Return whether the user is authorized to perform a given action on a pool.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – the method to perform

  • details (airflow.auth.managers.models.resource_details.PoolDetails | None) – optional details about the pool

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_variable(*, method, details=None, user=None)[source]

Return whether the user is authorized to perform a given action on a variable.

Parameters

  • method (airflow.auth.managers.base_auth_manager.ResourceMethod) – the method to perform

  • details (airflow.auth.managers.models.resource_details.VariableDetails | None) – optional details about the variable

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_view(*, access_view, user=None)[source]

Return whether the user is authorized to access a read-only state of the installation.

Parameters

  • access_view (airflow.auth.managers.models.resource_details.AccessView) – the specific read-only view/state the authorization request is about.

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

is_authorized_custom_view(*, fab_action_name, fab_resource_name, user=None)[source]

Return whether the user is authorized to perform a given action on a custom view.

A custom view is a view defined as part of the auth manager. This view is then only available when the auth manager is used as part of the environment.

By default, it throws an exception because auth managers do not define custom views by default. If an auth manager defines some custom views, it needs to override this method.

Parameters

  • fab_action_name (str) – the name of the FAB action defined in the view in base_permissions

  • fab_resource_name (str) – the name of the FAB resource defined in the view in class_permission_name

  • user (airflow.auth.managers.models.base_user.BaseUser | None) – the user to perform the action on. If not provided (or None), it uses the current user

get_permitted_dag_ids(*, methods=None, user=None, session=NEW_SESSION)[source]

Get readable or writable DAGs for user.

By default, reads all the DAGs and check individually if the user has permissions to access the DAG. Can lead to some poor performance. It is recommended to override this method in the auth manager implementation to provide a more efficient implementation.

security_manager()[source]

Return the security manager specific to FAB.

get_url_login(**kwargs)[source]

Return the login page url.

get_url_logout()[source]

Return the logout page url.

get_url_user_profile()[source]

Return the url to a page displaying info about the current user.
