[docs]def upload_commit_order_sorter(x: Table) -> Tuple[bool, bool, bool, str]: """ Function to sort tables for the commit phase of the upload. - "patient" must come before "patient_idnum", since ID number indexing looks at the associated Patient. - All of "patient", "blobs", and all ancillary tables must come before task tables, because task indexes depend on tasks correctly retrieving their subsidiary information to determine their :meth:`camcops_server.cc_modules.cc_task.Task.is_complete` status. (However, even though ancillary tables can refer to BLOBs, as long as both are complete before the task tables are examined, their relative order doesn't matter.) - Task tables come last. Args: x: an SQLAlchemy :class:`Table` Returns: a tuple suitable for use as the key to a ``sort()`` or ``sorted()`` operation Note that ``False`` sorts before ``True``, and see """ # noqa return ( != Patient.__tablename__, != PatientIdNum.__tablename__, not in NONTASK_CLIENT_TABLENAMES,, )
