141 | # Okay, problem being: | |
142 | # Migration #4 forgot to add the uniqueconstraint for the | |
143 | # new tables. While creating the tables from scratch had | |
144 | # the constraint enabled. | |
145 | # | |
a64abbb1 | 146 | # So we have four situations that should end up at the same |
ea91c183 E |
147 | # db layout: |
148 | # | |
149 | # 1. Fresh install. | |
150 | # Well, easy. Just uses the tables in models.py | |
151 | # 2. Fresh install using a git version just before this migration | |
152 | # The tables are all there, the unique constraint is also there. | |
153 | # This migration should do nothing. | |
154 | # But as we can't detect the uniqueconstraint easily, | |
155 | # this migration just adds the constraint again. | |
156 | # And possibly fails very loud. But ignores the failure. | |
157 | # 3. old install, not using git, just releases. | |
158 | # This one will get the new tables in #4 (now with constraint!) | |
159 | # And this migration is just skipped silently. | |
160 | # 4. old install, always on latest git. | |
161 | # This one has the tables, but lacks the constraint. | |
a64abbb1 | 162 | # So this migration adds the constraint. |
