I would say that it depends on what result you want to accieve:
1. You don't want results with no values for the field in object, in
that case it's better to cat out them with an adequate query (i.e.:
...&(myfield!=None));
2. You want to see "" (empty string) instead of "None" for the records
that has no value for the field in object, in that case you can fix the
represent function of the field with something like field.represent =
lambda v: "" if v is None else v;
I hope it could help.
Cheers
