From a842c554e699174fdcc3a771c968ac978c4135a8 Mon Sep 17 00:00:00 2001 From: Aleks Chirko Date: Fri, 24 Jan 2014 15:59:29 +0200 Subject: [PATCH] Change manila DB to have working unique constraint Because Manila DB uses 'soft delete', we can't use unique constaints properly. Solution is to change 'deleted' column from Boolean to the type of 'id' column and write value of 'id' to 'delete' on delete operation. To apply unique constr only to not deleted records we will be adding 'deleted' column to every uc from now on.
