From: Radek Czajka Date: Mon, 14 Jun 2010 11:11:55 +0000 (+0200) Subject: Allow tags with identical names. X-Git-Url: https://git.mdrn.pl/wolnelektury.git/commitdiff_plain/d95d8a5fe401479b8adaa10cb77012c130525efd Allow tags with identical names. Tags are now unique based on slug+category, instead of just slug. Category-qualified tag URL-s introduced. --- diff --git a/apps/catalogue/migrations/0008_unique_tag_category_slug.py b/apps/catalogue/migrations/0008_unique_tag_category_slug.py new file mode 100644
