[davidnemec]

This should fix import error in strawberry.ext.mypy_plugin for users who don't use pydantic introduced in latest version. Hopefully the new location of the import is fine.

Ah good catch! Can you add a release file for this?

[patrick91]

also I think it is safe to add a default to false 😊

so

IS_PYDANTIC_V1 = False

[davidnemec]

IS_PYDANTIC_V1 is used in if-else. Should I update it to if-elif and also set (and check in elif) IS_PYDANTIC_V2=False? 🤔

[patrick91]

I meant only in the expect except ImportError: if we can't import pydantic it means we don't have it installed, so the default for IS_PYDANTIC_V1 doesn't matter that much :)

Thank you!
