Describe the solution you'd like
I would like to be able to use pydantic v2 and fastapi-utils together. Can we build the support for pydantic v2?

Same issue here.

ERROR: Cannot install -r requirements.txt (line 1), -r requirements.txt (line 2) and pydantic==2.0.2 because these package versions have conflicting dependencies.
The conflict is caused by:
    The user requested pydantic==2.0.2
    fastapi 0.100.0 depends on pydantic!=1.8, !=1.8.1, !=2.0.0, !=2.0.1, <3.0.0 and >=1.7.4
    fastapi-utils 0.2.1 depends on pydantic<2.0 and >=1.0

Hi @dmontagu,
Are there any plans to release it in near future? Pydyantic v2 provides many fixes.

https://github.com/yuval9313/FastApi-RESTful is a fork of fastapi-utils that is more active and already has support for pydantic 2. Feel free to check it out.

https://github.com/priyanshu-panwar/fastapi-utilities is based on this project and has support for it.
