When creating a record from scratch, the client should call this with an

default values to ``values``, computes the remaining fields, applies
onchange methods to them, and return all the fields in ``fields_spec``.
The result is a dictionary with two optional keys. The key ``"value"``
is used to return field values that should be modified on the caller.
The corresponding value is a dict mapping field names to their value,
in the format of :meth:`web_read`, except for x2many fields, where the
value is a list of commands to be applied on the caller's field value.
The key ``"warning"`` provides a warning message to the caller. The
corresponding value is a dictionary like::
{
"title": "Be careful!", # subject of message
"message": "Blah blah blah.", # full warning message
"type": "dialog", # how to display the warning
