Subject: Only run archivalook migration if the tables aren't there.
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=c527242841e7c7408d4307cac0ef049a6db80930;p=mediagoblin.git

Only run archivalook migration if the tables aren't there.

Standard for anything existing before the Alembic move-over, but I
forgot this one.

* mediagoblin/plugins/archivalook/migrations/b10b5f822789_archivalook_plugin_initial_migration.py
  (upgrade): Add has_table check, skip if such a table already exists.
