The current project I'm working has at the time of writing 20 different forms (90% model forms) instantiated in different scenarios. Django doesn't automatically strip whitespace in text based fields. So instead of doing this:
class ContactMarketingForm(forms.ModelForm):
class Meta:
model = ContactMarketing
exclude = ('contact',)
def clean_notes(self):
return self.cleaned_data['notes'].strip()
def clean_name(self):
return self.cleaned_data['name'].strip()Instead I wrote a common class for all of my form classes to use:
class _BaseForm(object):
def clean(self):
for field in self.cleaned_data:
if isinstance(self.cleaned_data[field], basestring):
self.cleaned_data[field] = self.cleaned_data[field].strip()
return self.cleaned_data
class BaseModelForm(_BaseForm, forms.ModelForm):
pass
class ContactMarketingForm(BaseModelForm):
class Meta:
model = ContactMarketing
exclude = ('contact',)Now all text inputs and textareas are automatically whitespace stripped. Perhaps useful for other Djangonauts.
