http://code.google.com/p/web2py/issues/detail?id=980 Now it was closed with status fixed, but: -AFAIK, fileld.writable still has no effect in computed fields. You cannot set a computed field as writable with crud so it shows the widget. You can with SQLFORM (by using the fields argument), however, entering blank inputs don't trigger the compute function server side. -There's no modification of SQLFORM to process empty form fields as computable (in replacement of a previous or new record value)* -SQLFORM doesn't set computed fields as empty on form creation (I think this should be the default behavior)* * Perhaps it would be necessary to add different checks by field type and a standard way of detecting a blank input in each case. Of course, it's possible to show a given widget and do further record processing in the controller without depending on the computed field facility, but with this changes, it would save that extra code and give a more clean and web2py like interface. --
