From 2b332c3b9ab12ceee1e94fdef01c1eb3cb06c77a Mon Sep 17 00:00:00 2001 From: Griatch Date: Thu, 11 Jul 2013 09:51:52 +0200 Subject: [PATCH] Attribute cache is working, lots of other updates, but still not a cleanly updatable system. It seems the Attribute-migrations are not coming through properly. Fixed a misnamed table in the comm app. --- ev.py | 3 +- src/commands/default/building.py | 8 +- .../0011_renaming_channles_to_channels.py | 135 ++++++++++++++++++ src/comms/models.py | 2 +-
