• rev_number – The revision_number that the resource should be at.

class neutron_lib.context.ContextBase(user_id=None, tenant_id=None, is_admin=None, timestamp=None, tenant_name=None, user_name=None, is_advsvc=None, **kwargs)

Bases: RequestContext

Security context and request information.

Represents the user taking a given action within the system.

elevated()

Return a version of this context with admin flag set.

classmethod from_dict(values)

property is_advsvc

property is_service_role

property tenant_id

property tenant_name

to_dict()

Return a dictionary of context attributes.

to_policy_values()

A dictionary of context attributes to enforce policy with.

oslo.policy enforcement requires a dictionary of attributes representing the current logged in user on which it applies policy enforcement. This dictionary defines a standard list of attributes that should be available for enforcement across services.

It is expected that services will often have to override this method with either deprecated values or additional attributes used by that service specific policy.
