It sounds like you want to use Django/Postgres for the backend and then run a static site from Spaces Object Storage. Spaces isn’t setup to automatically treat directories and files there as a “website” which is why it isn’t coming up the way you expect.

However, we have released our new App Platform which has a fully built out solution for hosting static sites and can also be directly integrated with your code on Github, so I would recommend that you use that instead.

You can find more information on that here:
