registration: Enforce realm is None only if realm_creation. Commit d4ee3023 and its parent have the history behind this code. Since d4ee3023^, all new PreregistrationUser objects, except those for realm creation, have a non-None `realm`. Since d4ee3023, any legacy PreregistrationUsers, with a `realm` of None despite not being for realm creation, are treated as expired. Now, we ignore them completely, and remove any that exist from the database. The user-visible effect is to change the error message for registration (or invitation) links created before d4ee3023^ to be "link does not exist", rather than "link expired". This change will at most affect users upgrading straight from 1.7 or earlier to 1.8 (rather than from 1.7.1), but I think that's not much of a concern (such installations are probably long-running installations, without many live registration or invitation links).

migrations: Remove unused imports. Signed-off-by: Anders Kaseorg <andersk@mit.edu> 2019-02-02 23:53:20 +01:00			`from django.db import migrations`
migrations: Use django.db.backends.postgresql.schema. This replaces django.db.backends.postgresql_psycopg2, which has been an alias to django.db.backends.postgresql since Django 1.9. 2020-04-27 07:19:08 +02:00			`from django.db.backends.postgresql.schema import DatabaseSchemaEditor`

python: Sort migrations/management command imports with isort. This is a preparatory commit for using isort for sorting all of our imports, merging changes to files where we can easily review the changes as something we're happy with. These are also files with relatively little active development, which means we don't expect much merge conflict risk from these changes. 2020-01-14 21:59:46 +01:00
