- new setting to enable user exports defaults to False
- add setting to enable and disable user exports
- do not allow user exports when using s3 storage
- do not serve non-image files from /images/ (requires update to nginx settings)
- increase default file upload limit to 100MB to enable user exports to be imported (can be changed in .env)
I had the bright idea of creating this update script but it doesn't work
and hasn't been maintained, so it's just sitting there causing confusing
and requiring weird things to exist in other places.
Now, the unused `version` field can be removed and I can scrap the
management command for getting versions.
If a theme is uploaded incorrectly or has errors in it, users can still
select the theme but it will cause a 500 error on every page, making the
app unusable and also making it impossible for them to switch to a
functional theme.
A better fix would be to fail gracefully, but in lieu of that, this will
at least let admins confirm if a theme is broken safely.
- makes user_import_time_limit a site setting rather than a value in settings.py (note this applies to exports as well as imports)
- admins can change user_import_time_limit from UI
- admins can cancel stuck user imports
- disabling new imports also disables user imports
The migration uses `RESTRICT` instead of `PROTECT`, which is both more
correct, but also those values need to be identical, otherwise Django
thinks that there's a migration missing and will refuse to apply any
new migrations.
