🐛 Add update_forward_refs with local models

[Kludex]

Hi there! 👋

Let me start with: I don't know exactly how this start failing. 😅

Maybe you'll understand better looking at the explanation: pydantic/pydantic#2678 (comment)

The solution I proposed is the one presented in the link above. An alternative could be:

ArgModel.update_forward_refs(**globals())

(but you'll get more than you need... and I'm not sure it works in all cases)

Omg, thanks! 🙏🎉 (Also, I feel kinda stupid for not seeing this... I even vaguely remember thinking "hmm, I wish there was a way to just tell it what the modules are 🤔" hahaha)

So I'm assuming the reason it doesn't work out-of-the-box, even with the imports in the top scope of util.py, is because the actual forward refs are defined outside of that scope? And that's what actually matters, not the scope updating the forward refs?

I'll add some small comments for our team that are mostly about how we want to structure the call to update_forward_refs, now that we know it's possible to just pass in the refs like this.

I wonder if we should just pass in all the **types here? Because in theory, there are more types that the forward functions could use. And using the globals() is more vague, and makes it less obvious that the imports in util.py matter.

[ines]

Okay, it can't be **types because that's a module, but you get the idea 😅

I see. I guess it's fine now? 😗

[ines]

Yeah, I think the solution I came up with works and does what we want 🎉 Thanks again!
