 In an effort to support out-of-date installations of our app, I had to keep a JSON column in our database. The column is obsolete, as are the values within it; but these installations continue to use it. So, knowing this, I decided to put the proper values into the column. I didn't want to pollute the code of our services to do so, though. So I made it into a `GENERATED` column.

 I still saw requests coming in through an old Cloudflare-Worker-based proxy I had set up, before I released the current one, which rewrites `m3u8` files on-the-fly, besides proxying the segment files themselves (among other features). I updated our website and app to use the new proxy; where were these requests coming from? I inspected some requests as they came in using the Cloudflare interface, and I found that the User Agent was always one of our apps; and different versions of it at that. We still had un-updated versions of our app out in the wild, but I also saw requests from the latest version! How could this be?

 React-admin is a wonderful framework, and is quite flexible; but if you need something that it doesn't offer, it's very difficult to dig through the docs to find out how to do it.
