underwriting_preferences

Delete the caller's saved preferences for one Underwriting screen.

Code
The screen opens on its default from then on. Deleting when nothing is
saved succeeds.

Parameters
----------
scope : str
    The screen. One of: ``workbench.task_queue``.

Returns
-------
dict
    ``scope``, with ``preferences`` and ``date_updated`` null.

Return the caller's saved preferences for one Underwriting screen.

Code
Parameters
----------
scope : str
    The screen. One of: ``workbench.task_queue``.

Returns
-------
dict
    ``scope``; ``preferences``, or null when nothing is saved; and
    ``date_updated``. Saved values that are no longer valid, or that the
    caller may no longer use (for example the Triage view after a role
    change), are left out, and the screen uses its default for them.

Replace the caller's saved preferences for one Underwriting screen.

Code
Parameters
----------
scope : str
    The screen. One of: ``workbench.task_queue``.
preferences : dict
    The whole set to keep; anything left out reverts to the screen's
    default. Keys the scope does not define are ignored, and an invalid
    value fails the request. For ``workbench.task_queue``, the Task Queue's
    saved filters; the queue always opens on My Tasks, and a tab's saved
    filters apply whenever it is opened. Every key is optional:

    * ``bucket``: ``active``, ``on_hold`` or ``archived``, shared by every
      tab. Kept only for users who may choose a lifecycle bucket.
    * ``views``: one entry per tab, keyed ``my_tasks``, ``all_tasks``,
      ``submissions`` or ``triage``, each with:

      * ``status_filter``: ``all``, ``overdue``, ``due_today``,
        ``blocked`` or ``unassigned``.
      * ``list_mode``: ``by_task`` or ``by_policy``.
      * ``filters``: lists of up to 200 values of up to 255 characters each, as ``retrieve_tasks``
        takes them: ``task_types``, ``statuses``, ``transaction_types``,
        ``lobs``, ``stages``, ``priorities``.
      * ``due_date``: the picked day, ``YYYY-MM-DD``, kept as picked.
      * ``sort``: ``sort_by`` (a ``retrieve_tasks`` sort key) and
        ``sort_order`` (``asc`` or ``desc``).

Returns
-------
dict
    The saved preferences in the shape ``retrieve_underwriting_preferences``
    returns, after the values the caller may not use are dropped.
