Fixes

Fixes #4344 by @AetherUnbound

Description

This PR modifies the Django Admin registrations for various media report related views in order to prevent exposing access to the primary media tables in production. Queries that are made to these tables are often naive and, for such a large table, cause significant issues. However, they're extremely useful to have when running the application locally in order to easily create/reference media while we build out the content safety reporting features.

This will necessarily reduce our available features in production, but because of the nature of the failure which caused this, we couldn't have used those features anyway!

Testing Instructions

Tests should pass. You can also verify this locally by:

  1. just api/init
  2. Visit http://localhost:50280/admin/ and observe that Image Decision shows up in the list of available models for site administration
  3. Add ENVIRONMENT=production and DJANGO_SECRET_KEY=blahblahblah to api/.env
  4. Run just down && just a to restart the API stack
  5. Visit http://localhost:50280/admin/ and observe that the decision views are no longer present

It's unfortunate that these models have to be removed from the admin but also understandable. Thanks for fixing this so quickly, LGTM!

Agreed, but only for prod! Hopefully we'll have the official features for actually handling this well available soon 😄

I don't understand why this is the solution? Is the problem not the media object identifier auto-complete query on the Django admin page?

https://docs.djangoproject.com/en/5.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.autocomplete_fields

There's no way we need to entirely remove these pages from Django admin, that's just not how this kind of thing works. There is something about the admin configuration causing it to make the query, it isn't an inherent feature of those page, but something we can change.

Was this meant as a temporary solution? I'm confused about what the long-term intention is here. @AetherUnbound can you clarify on this? This seems a fine stop-gap if we don't know what is causing it, but it's under no circumstances an acceptable long-term solution.

This is indeed a temporary solution. The <Media>Decision admin views were added in a very naive way by me in #4254 as a means of creating these records locally easily. The naivete of the implementation led to, I believe, some bad queries in production when trying to render the page. In my mind, it's fine to disable those views in production until we have the actual decision-creation mechanism appropriately set up, since the current exposure of those tables was for testing anyway. My assumption was that future tasks in the moderation basic functionality milestone would actually expose the necessary views there in a more appropriate way.

The problem is also the media object identifier auto-complete query, which is why those were production deferred on the other models. I also deferred the search fields because those are used by the auto-complete query and (again, my assumption) cause unoptimized queries as well.
