Hello,
I have several forms that I subclass from a subclass of newforms:
# newforms is aliased as forms
class StrippedFieldsForm(forms.Form)
def strip_field(self, field, error_message):
if (self.clean_data.get(field)):
data = self.clean_data[field].strip()
if (0 == len(data)):
raise forms.ValidationError(error_message)
else:
return data
else:
return ''
class DerivedForm(StrippedFieldsForm):
# ... fields go here ...
# ... for each field I have to do ...
def clean_field1(self):
return self.strip_field('field1', 'Field 1 contains only whitespace.')
def clean_field2(self):
return self.strip_field('field2', 'Field 2 contains only whitespace.')
This gets tedious as there are forms with 10 or more fields.
My question is, is there another way to apply strip_field to *all* or
a select list of fields automatically? My last resort is to override
form.clean() for StrippedFieldsForm.
