Support pydantic >= 2 about prisma-client-py HOT 9 CLOSED

Completely agree, we want to migrate to the prisma client but this is currently a dealbreaker as we use pydantic 2 in the rest of our application :/

from prisma-client-py.

fastapi==0.100.0 still supports pydantic v1. However, it'd be nice if prisma-client-py supported pydantic v2. FastAPI will deprecate pydantic v1 in the future.

Hey all, sorry for the delay here. I unfortunately haven't been able to spend much time working on Prisma Python recently.

However this is the highest priority item for me, I'll try and get support out as soon as possible. Please note that this will take a lot of work as we use Pydantic extensively throughout the library & rely on features that have been changed fundamentally in v2. You can track my progress in #763.

The auto-migration tool is sadly not very helpful as I want to maintain support for Pydantic v1 & it doesn't help with that.

Understood, thanks for all the effort you're putting into this in the first place! You've made a very useful tool.

Support for v2 has been released in v0.10.0, please give it a try and let me know if you run into any issues!

from prisma-client-py.

Wow, this was fast! I'll see if it works out of the box for our tests.

Indeed, this is a big issue for us too. @RobertCraigie if you get a moment to think about this, how much work do you think it will take? Plz let us know also what priority this has for you.

Some points from the migration guide:

• They published a code transformation tool (beta)
• Pydantic v2 seems to still offer all pydantic v1 classes under a new package. Not sure if the code transformation tool would work if we use this fallback though.

We also need this, as langchain will deprecate support for pydantic v1 on 25th of august
