This patch adds an "AsString" converter: 415a418,431 > class AsString(ValidatorConverter): > """ > > Converts things to string, but treats empty things as the empty > string. I'm quite sure it doesn't handle every degenerate case. > > """ > > def convert(self, value): > if value: return str(value) > if value == 0: return str(value) > return "" > > Good for things like TextField, where you may want the empty string instead of None (then again, you may want None.) |
