No, "fields" is an argument of SQLFORM:
form = SQLFORM.factory(..., fields=['field1', 'field2', ...])
Anyway, setting the _readonly attribute of the input widget and setting
writable=False in the Field() definition do two different things. The
former makes the input element read-only in the UI but is less secure
because it does not prevent writes on the server. The latter does not use
an input element to display the data in the UI, and it also prevents writes
on the server.
