Without having tested the code, it looks good upon reading and I'd be happy to merge it, as you've said it all works and it aligns with all the stuff we've discussed as a group to this point.

My only question is about how we could potentially quarantine the user_profile stuff? Or whether we want to keep it there for now as scaffolding.

[Archer-Key]

As for the user_profile stuff I think we could either just remove it as it's a separate app, or we could leave it for our own use such as if we want to allow the user to have a profile.

I don't think its of enough importance to require a decision to be made at the current moment.

How did you test your code? I'm running my own version now, but just wanted to make sure mine does everything yours does.

So far I've just used the admin endpoint to create items and then the api endpoints (api/planner/[task/topic/time]/) to view the data and ensure its what's expected.

Ok, I haven't tested with data but I've tested the paths and it seemed to work. I'll accept the PR now.
