# This migration was to add a constraint that we lost in the Django
|
|
# 1.4->1.8 upgrade. But since the constraint used to be created, production
|
|
# would already have the constraint even before running the migration, and
|
|
# running the migration would fail. We needed to make the migration
|
|
# idempotent. Instead of reverting this migration while we did that, we
|
|
# edited it to be a SQL no-op, so that people who had already applied it
|
|
# wouldn't end up with a ghost migration.

# It had been:

|

# migrations.RunSQL(

# "create unique index email on auth_user (email);",
|
|
# "drop index email on auth_user;"
