I'd implement it as a clean_fieldname method. The fact that in the above
you're having to mess around with errors dictionary manually for
something this simple is a bad smell to watch out for.
form
----
def ClubForm(forms.Form):
name = forms.CharField(...)
...
def clean_name(self):
slug = slugify(self.cleaned_data['name'])
if Club.objects.filter(slug=slug).count():
raise forms.ValidationError(u'Club is already in database')
return self.cleaned_data['name']
view
----
if request.method == 'POST':
form = ClubForm(data=request.POST)
if form.is_valid():
club = form.save() # Do the slugify() in your save method
return HttpResponseRedirect(club.get_absolute_url())
else:
form = ClubForm()
