Hi Guys,
I am quite new to Django, I'm having few problems with validation
forms in Admin module, more specifically with raising exception in the
ModelForm. I can validate and manipulate data in clean methods but
cannot seem to raise any errors. Whenever I include any raise
statement I get this error "'NoneType' object has no attribute
'ValidationError'". When I remove the raise part everything works
fine. Any tips or suggestions on doing such a thing properly ?
Here's an example of what I'm doing in Admin.py:
###admin.py####
class FontAdminForm(forms.ModelForm):
# Import form from a model
class Meta:
model = Font
def clean_name(self):
return self.cleaned_data["name"].upper()
# clean description.
def clean_description(self):
desc = self.cleaned_data['description']
if desc and if len(desc) < 10:
raise forms.ValidationError('Description is too short.')
return desc
class FontAdmin(admin.ModelAdmin):
form = FontAdminForm
list_display = ['name', 'description']
admin.site.register(Font, FontAdmin)

Thanks,
Adnan
