using models as fastAPI response_model freezes fastAPI docs

[JoshDLane]

Bug description

When i try to use a model from prisma.models as a response_model on a fastAPI endpoint, the fastAPI docs freeze when I try to open that endpoint to see the response type. I have tried to use partials to resolve this. I can only get it to work when i have no relational fields in the partial. I find it hard to believe its completely freezing just because the type is large. Anyone have experience with this?

• is there a way to control the depth of the relation generated for partials like we can do when querying?

How to reproduce

Here is a simple partial im generating to test this and its failing. pillar model also has some relations.

from prisma.models import Bot
ChatOverview = Bot.create_partial("ChatOverview", include={"pillar"})

and in fastAPI endpoint...

response_model=ChatOverview,

I haven't encountered this myself, what FastAPI version are you using?

I'd currently recommend searching the FastAPI repository to see if anyone else is running into this if you haven't already & if you can reproduce this without using Prisma then open an issue with FastAPI.
