hi,
im thinking about how to make my slug generation a bit more functional.
I dont want my users to think or write their slugs so they have to be
generated by a field in the model. usually this is the title field.
Now the problem is that there is the possibility that a slug could be
the same as one of another object in my app.
Of couse because i dont want the users to edit or write their slugfields
a 'unique=True' doesnt help because it would invalidate the form
and the user wouldnt understand why.
i was thinking to put a bit of logic in the models save or use the
pre_save signal.
def save(self):
if not self.slug:
genslug = slugify(self.title)
obj = MyModel.objects.filter(slug=genslug)
if not obj:
self.slug = slug
else:
#do something to generate an unique slug
super(MyModel, self).save()
would something like this work?
when does the field validation happen?
