I upgraded this morning from Django 1.1.1 (r11312, I think) to the
most recent HEAD revision (r11794) and it appears that some changes
have been made to the form validation scheme again. I have a blog app
wherein I want the application to be able to automatically generate
slugs from post titles. Previously, I had used something like this in
the "add blog post" view:
if request.method=='POST':
form = AddArticleForm(request.POST)
if form.is_valid():
article = form.save(commit=False)
if not form.cleaned_data['slug']:
article.slug = slugify(form.cleaned_data['title'])[:
25].rstrip('-')
article.save()
And this worked pretty nicely. Now, however, when I try to submit a
form with a blank "slug" field, I get redirected back to the form with
a notice that I need to fill in that field.
I tried overriding the Article model's clean() function like so:
def clean(self):
if not self.slug:
self.slug = slugify(self.title)[:25].rstrip('-')
That didn't help the problem. So, where's the right place to put this
code? New custom validate() function in the form class?
