Looks like you want the "unique_together" Meta option: http://www.djangoproject.com/documentation/model-api/#unique-together rather than specifying the slug as unique. > The other problem is in those cases where there will be a duplicate > slug.

This is a bit more work (meaning, Django doesn't do this one for you with one line of code :) To prevent nettlesome race conditions, likely the best thing to do is intercept the POST in a transaction, check to see if the slug already exists for the given user, and then formulaicly find the next unused one. You might do something like existing = Foo.objects.filter(user_id=request.user.id) # new_slug = the proposed slug from the user existing = existing.filter(slug__startswith = new_slug) i = 0 # to keep track of the highest index we've come across offset = len(new_slug) for foo in existing: s = foo.slug[offset:] # strip off the matching slug part if i == 0 and not s: # if we already have an exact match, # we need an index if we don't # already have one i = 1 elif s.isdigit(): x = int(s) if x > i: i = x + 1 if i > 0: new_slug = "%s%i % (new_slug, i) NB: This code is 100% untested and may only work in my head ;) This does have odd behavior if they have two slugs like "elvis2000" and "elvis" and then try to add "elvis" a second time...it will result in "elvis2001" instead of "elvis1". Once you've modified it, make sure you redirect to the corrected slug URL too. :) -tim --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
